History of Hydraulic Jacks

2008-08-22T02:45:00.003-07:00

Hydraulic jacks are widely used all across the globe. They have a lot of relevance in the present era, as they have made an incredible contribution in making our life much more comfortable than it was before. These jacks have outweighed conventional screw jacks that were in use at some point of time. They consist of two cylinders joined together. It works on the principle of Pascal's law which suggests that when there is an increase in pressure at any point in a container of fluid, there is an equal increase in pressure at every other point in the container.

History

The origin of hydraulic jacks can be dated several years ago when Richard Dudgeon, the owner and inventor of hydraulic jacks, started a machine shop. In the year 1851, he was granted a patent for his hydraulic jack. In the year 1855, he literally amazed onlookers in New York when he drove from his abode to his place of work in a steam carriage. It produced a very weird noise that disturbed the horses and so its usage was limited to a single street. Richard made a claim that his invention had the power to carry near about 10 people on a single barrel of anthracite coal at a speed of 14 m.p.h. Dudgeon deserves a special credit for his innumerable inventions including the roller boiler tube expanders, filter press jacks, pulling jacks, heavy plate hydraulic hole punches and various kinds of lifting jacks.

Common Types

Floor Jacks: These jacks are primarily used to lift heavy equipments from the surface of the floor. It is more often used to change the tyres of vehicles. Floor jack is known by different names such as garage jack and car jack. Nowadays, you can find more powerful jacks in the market that use hydraulic power for maximum lift.

Hydraulic Bottle Jacks: Hydraulic bottle are versatile since they can be placed in tight spots and provides good leverage. They have a longer handle as compared to rest of the hydraulic jacks and push up against a lever that gives a lift to the main lift arm. With their use, it is possible to give a greater lift per stroke. They are extensively used in the construction of buildings and repairing the foundation of houses. It has also been found to be very useful in search and rescue operations.

Long Ram Jacks: In simple terms, it is a hydraulic jack with a long size ram. Its lever handle is quite easy to use. It is primarily used for performing various types of repairing work.

Shop Press jacks: They are of great use in press jobs where there arises a need to generate tremendous pressure with minimum effort.

Another popular form of jack that enjoys high demand in the market is the Porta Power Jack.

Hydraulic Pumps

2008-08-22T02:45:00.002-07:00

Hydraulic pumps convert mechanical energy and motion into hydraulic fluid power and are usually powered by gas or electricity. However, hand and air driven pumps are also utilized. There are three main types of hydraulic pumps used in the fluid power industry, namely vane pumps, gear pumps, and piston pumps. These are all positive displacement pumps, meaning that they transfer a calculated quantity of pressurized hydraulic fluid into a hydraulic system. This fluid progresses to the necessary component and its pressure is reconverted to mechanical force.

A general hydraulic pump design can be further categorized into specific groups. For example, piston pumps can be radial, axial, in-line reciprocating, or axial bent-axis piston pumps. Vane pumps are either cam or sliding vane pumps. Pumps can be further subcategorized according to the modifications made for special applications. These pumps show a great variety in design. Irrespective of the design, all hydraulic pumps are to be used with fluids of definite viscosity. Changes in fluid viscosity will cause altered performance, often lowering the efficiency. Most pumps get damaged by any solid particles in hydraulic fluid, and, hence, require a filtration system.

A hydraulic pump is a very important component of construction, manufacturing, and machining equipment. It is responsible for a machine's precision, its efficiency, and overall performance of an entire system. Various materials are used in hydraulic pumps to minimize wear and provide consistent performance. The type of material used varies according to pressures and temperatures that a hydraulic system will undergo. A number of plastics, synthetic rubbers, and steel alloys are used in the manufacturing of hydraulic pumps. High-strength alloys and polymers are used in high-pressure systems.

When choosing a pump, it is recommended to consider factors like operating pressure, temperature, and frequency. For applications requiring minimal pressures, less expensive, low-pressure pumps are available. Some examples of hydraulic pump manufacturers are Lifco Hydraulics, Inc., Flint Hydraulics, Inc., HYSECO, Inc., and Craft Fluid Systems.

Hydraulic Boat Lifts

2008-08-22T02:45:00.001-07:00

Among a variety of technologically advanced and mechanically upgraded boatlifts, hydraulic boatlifts deserve special mention. In the search for protection that's tough on waves - but easy on the environment and community aesthetics - many have found a solution in floating wave attenuators.

Most hydraulic boatlifts are standard with non-corrosive stainless steel bolts, stainless cable and brass nuts, giving you many years of service while maintaining a clean appearance. Thick urethane sheaves are used to maximize cable life and to ensure lasting performance under heavy use. Most of the hydraulic vertical lifts offer rigid diagonal V-bracing on both sides, giving uncompromised strength on demand when your boat is raised to maximum height. There are a number of companies who offer a variety of hydraulic boats ready to give these pleasures and advantages. Certain characteristics and features of hydraulic should be highlighted:

The hydraulic cylinder is enclosed in a beam assembly. Stainless bolts, pins, and brass nuts are used on all lifts and accessories to provide years of reliable service. The hydraulic pump, motor, and battery are enclosed in a poly box that can be locked to protect your investment.

The hydraulic lift comes standard with a two-button remote for raising and lowering the lift. Additional remotes are available and are easy to program to each specific unit.

No matter which kind of hydraulic boatlift you choose, see if you can get a one-year warranty, or an even longer one if possible. That way, if it ever breaks down, you won't end up throwing away even more money than you spent in the first place. A boatlift is meant to save you money on repairing your boat; it should never become an ongoing expense unto itself.

New DISCMAN Manufacturing Software from DISC based on BASIS International's BBx

2008-02-14T02:53:00.001-08:00

Columbia Pictures' "Anaconda" Wouldn't Make A Move Without Them

The giant Anaconda snake that slithered its way across theater screens early this year wasn't given "star" billing and won't be considered for an Academy Award. If it could win the "best actor" title, however, it might include Distributed Information Systems Corporation, DISC(R), and extended Business Basic, BBx(R), in its long list of on-camera "thank you's." This particular Hollywood snake is one of many hydraulically operated devices found in everything from the Dumbo ride in Disneyland to the trash compactor in the average garbage truck. DISC is a software supplier to distributors who serve the behind-the-scenes world of hydraulics and pneumatics -- including those specifically involved in making the "Anaconda" and its audiences squirm. The company's DISC software has been used for years in running distribution and manufacturers' rep businesses on IBM RS/6000 platforms.

DISC's new DISC*MAN(TM) has been developed to support manufacturing firms in general, and those in fluid control systems in particular. DISC*MAN provides them with facilities for scheduling, inventory management, opening new jobs, partial shipment accounting, drill-down cost inquiry, and unlimited levels of bills of material, to name a few. The new system borrows heavily from the 2,500-program suite for distributors, but adds and modifies hundreds of modules. DISC*MAN, like DISC, is implemented in BASIS International's version of extended Business Basic, BBx, and runs on the IBM RS/6000. "BBx made production of the new system much easier," says Ray Hrdy, DISC's vice president of technology. "Because it's an interpreted language, coding and checkout was much quicker. Our developers could stop, fix, and restart an operation without first going back to recompile. That saves a lot of time.

"Its CALL program capabilities allowed us to access common procedures from any part of the program without having multiple copies compiled in. That's a very powerful feature," added Hrdy. "And our ODBC program for database access is directly based on the BASIS ODBC Driver(TM). Having that made it possible to import a bill of materials directly from a CAD/CAM system, automatically generating a customer order and job.

"In fact, I'd say that BBx was one of the reasons that the first release of DISC*MAN had fewer bugs than any new large-scale development this company has ever been involved with."

DISC*MAN is available directly from Distributor Information Systems Corporation, 135 South Road, Farmington, CT 06032-2556. The company is an IBM Premier Business Partner and has twice been awarded IBM's "Mark of Quality" award. DISC can be reached by phone at 800/PIC-DISC or 860/674-0550, by fax at 860/678-8601, or at its e-mail or web addresses mktg@discmail.com and www.disclink.com .

What You Should know Before Shelling Out The Big Bucks To Buy A Boxflex Treadclimber

2008-02-02T02:37:00.000-08:00

Lately there has been a lot of dispute in the fitness world over a particular piece of exercise equipment called the bowflex treadclimber. Supposedly, you can get fantastic results using this machine without having to resort to grueling exercise like running due to the fact that the TreadClimber's unique use of a combination of a combination of movements.

To date there are 5 treadclimber models available. This article will attempt to sort these machines out for you and let you the good, bad, and the ugly about the treadclimber line.

All of the Boxflex treadclimbers combine the forward action of a treadmill, upward action of a stair climber, and low-impact motion of an elliptical trainer. It would seem that this is the ultimate workout machine. And it would be if it weren't for a minor "glitch" that we have discovered on the lower end models.

What we have found is that with the base models is that there is not a smooth resistance transition. So what the heck does that mean?!

Resistance is what makes the treadclimber adjust from easy to hard to actually tread on. Contrary to what people think, it has nothing to do with making the machine go fast or slow. Generally speaking, most machines that have resistance ability have little arrows on the center console to let the user change the resistance. The Bowflex Treadclimber however does not include these arrows. Instead it has a hydraulic system with knobs above each piston. It is nearly impossible to change these resistance levers while in motion using the machine. As a matter of fact Bowflex actually strongly suggest that you get off the machine when changing the resistance.

If you can get past this little gripe, then this IS actually a great machine that can lead to rapid weight loss. Overall this machine has a customer satisfaction rate of over 90 percent, which is good.

The bottom line is that if you don't expect to change the resistance during your workout plan and if you are looking at the treadclimber1000, for only $15 additional per month you get increased speed, additional bells and whistles and a much better user console. If you have cash to buy the 5000 or if you can afford the payments, then this is simply the best of the lot.

Why Replace Your Struts and Shocks?

2008-02-02T02:36:00.001-08:00

You would need new shocks, and or struts if you are currently experiencing one or more of the indications to follow. Worn out, damaged, or leaking. Leaking is the easiest to determine, this is by basically checking for decrease in the fluid level in the reservoir. If the reservoir is not full, look for oil, or wetness on the shocks and struts. While you are at it, check for apparent broken mounts, and dented housing.

If you are not experiencing any of the indications, and did not see any visual leaking signs, however, still unsatisfied with the handling of your car when towing a trailer, or hauling an overload, you may want to consider upgrading the original factory shocks and struts. The upgrade would provide you with improved handling, and a smother drive, given that the new shocks are stronger, and stiffer.

Most people choose to replace the factory shocks and struts on older cars to strictly improve the overall quality of the drive. This eliminates the bouncing and rocking on rough roads. Furthermore, you may decide to upgrade your shocks and struts if you are interested in performance handling. This is archived by upgrading to gas charged shocks and struts. This type is charged with high pressure of nitrogen gas, which minimizes the hydraulic fluid foaming inside the shocks. This essentially reduces fading on rough roads, and assists in maintaining control at sharp turns.

Moreover, there are shocks and struts that fall into a different category. Heavy duty shocks and struts distinguished itself over the factory shocks and struts by a larger diameter pistons. This provides an increased control and improved resistance. Heavy duty shocks and struts are considered by experts to be too harsh for everyday driving. Last but not least, the air-assisted shocks. You would want to consider this type if you are constantly towing a trailer, or hauling extra cargo. It is also known as the overload, surrounded by a coil spring to help increase the loading capacity of the suspension. It may be useful to mention that the overload type dedicates a stiffer ride than the standard shocks, however, is equipped with an adjustable air bladder to assist in carrying extra weight.

Injection Molding Machines

2008-02-01T02:22:00.000-08:00

The injection molding process was invented in 1872. Since then, the injection molding business and the plastic industry has ballooned into a multi billion dollar business venture. In fact, thirty two percent of plastics by weight are processed through injection molding. Injection molding has greatly helped in making the US economy boom because through it, cheap and durable consumer and industrial items essential to almost all industries is made possible.

Components of the injection molding machine

The injection molding machine converts granular or pelleted raw plastic into final molded parts through the use of a melt, inject, pack and cool cycle for thermoplastics.

A basic injection molding machine is typically composed of the following: injection system, hydraulic system, mold system, clamping system and control system. The clamping tonnage and shot size are both used in identifying the dimensions of the injection molding machine for thermoplastics, which is the main factor in the whole process. Other consideration include rate of injection, pressure, design of screw, thickness of the mold and distance between tie bars.

Functions of the machine

The injection molding machine can be classified into three categories, namely: general purpose machines, precision/tight-tolerance machines and high-speed thin-wall machines. All three types require auxiliary equipment to function. These support equipment includes dryers (resin), material handling equipment, granulators, mold temperature controllers and chillers, part-handling equipment and part-removal robots.

There are a lot of companies specializing in quality injection molding, but they are not all the same. The best ones fast, flexible and customer driven both for large and small quantities. These companies usually have state-of-the-art facility with full scale thermoplastic and thermoset capabilities, computer-aided manufacturing, skilled machine operators and quality assurance team.

The Benefits of Electric Wheelchair Lifts

2008-02-01T02:20:00.000-08:00

Electric wheelchair lifts help to move the wheelchair to various places at multiple levels. Electric wheelchair lifts are less expensive than hydraulic wheelchair lifts and are easy to maintain. They contain an emergency, battery-lowering device which makes them ideal for use during power outages. Electric lifts can be fitted with automatic door openers or telephone jacks as per requirements.

Electric wheelchair lifts come in many different types, including home stair lifts and automobile lifts, as well as van ramps.

Home Stair lifts can be installed anywhere inside or outside the house. They are designed to take up less space and to be quiet and comfortable. Home stair lifts can rise up to 23 feet and can lift up to 350 pounds. Some custom designed lifts can even handle more weight. The price of home lifts ranges between $2,500 and $4,000.

Automobile lifts can be fitted into automobiles to accommodate electric wheelchairs. They are very easy to operate and can be operated by one person. They can also be assembled and disassembled easily. Automotive lifts can be fitted onto most vans and cars. The price of automobile wheelchair lifts can range from $700 to $3,000.

Wheelchair van ramps help to lift the wheelchair into a van. Van ramps are much more affordable and easy to use as they are spring-loaded for easy lifting. They are also easy to maintain, as they are not mechanical. Van ramps can be folded in half and stored vertically, thus minimizing storage space. The price of wheelchair van ramps usually ranges between $500 and $1,100.

Electric wheelchair lifts are made of strong materials for durability. They are permanently lubricated and contain steel-hardened gears for resisting corrosion. Electric wheelchair lifts are available with a number of options like rocker switches in the hand-held control, manual back-up systems (in case of power failure), an emergency crank through handle, and limited wiring.

Water Rower -- Just Like a Cruise Down the River Without Getting Wet

2008-01-31T03:39:00.001-08:00

I used to row competitively in my youth, but since then, my rowing exercise had been limited to occasional workouts on an aging hydraulic machine.

I had no idea how much technology had advanced in this area, until I was offered a trial of a new WaterRower exercise machine.

The first obvious difference that I noticed was the use of a flywheel which used paddles to connect to a moving mass of water. Just like rowing on water, the connection was fluid, with none of the jerkiness and jarring typical of other rowing machines.

The WaterRower’s flywheel has been designed to emulate the dynamics of a boat moving through water. When rowing, the workout is generated by overcoming the effect of drag as the boat moves through the water… So with the Water Flywheel the workout is generated by overcoming the effect of drag as the water moves past the tank.

Many rowing machines imitate the action of rowing, but they do so mechanically and often lack the natural dynamics experienced when a boat and crew glide down a river. When a crew row down a river they work to overcome the effect of drag which acts against the hull of the boat. The faster the boat is propelled the greater the drag and the harder the crew must work.

The flywheel reproduces these same natural dynamics.

Like other naturally performed aerobic pursuits such as swimming, running and cycling, to increase your intensity you don’t increase resistance, you simply swim, run, cycle or row harder. The faster you go the higher your intensity.

When each crew member on a boat pulls a stroke, he or she works to accelerate the mass of the boat and crew. The effort is applied evenly throughout the whole stroke, utilizing the muscles of the legs, torso and upper body in unison, exercising the whole body uniformly.

Similarly, the rowers flywheel responds to the work applied, allowing constant effort through the whole stroke. This is unlike resistance based machines where effort is high at the beginning of the stroke and fades as the resistance is overcome.

My old hydraulic rower replicates the rowing action mechanically. This harsh action (as most rowing machine users will be aware) creates a mechanical fatigue, generating soreness and aching which are not experienced when actually rowing on water. The WaterRower replicates the action naturally, and hence is free from this mechanical fatigue.

This makes the exercise as pleasant as a row down the river. When rowing, an oarsperson works to overcome the effect of drag acting on the boat. The faster the boat moves, the more drag is created the harder the oarsperson must work to maintain that speed. The limit to how much work can be done is the oarsperson, their physiology, their ability to do work. The WaterRower’s flywheel replicates this self paced dynamic.

Ask most fitness equipment users to work harder and they will immediately reach for the knob or button designed to increase resistance. Naturally performed aerobic exercises such as rowing, swimming, running and cycling dont have knobs to turn or a buttons to push, so how do you work harder?

In naturally performed aerobic exercises you increase or decrease your exercise intensity simply by going faster or slower. You do not increase an imposed resistance on yourself, you simply choose the intensity at which you wish to exercise and go at a speed which relates to that intensity.

The equipment seemed to exercise all muscles evenly, and even a brief workout should burn calories and tone your body whether you are young or old, fit or unfit, ( like me!)

Just like a cruise down the river and I did not even get wet!

Massage Tables

2008-01-30T01:38:00.001-08:00

Massage tables are essential equipment for all massage therapists. However there are different tables you can have depending on the type of massage treatment the client needs. If you travel to your clients, you will need a portable massage table, which is the same size as a regular table, but considerably lighter and easier to carry. If you combine a range of therapies in your office, then you could benefit from an hydraulic or electrically adjustable table.

For those therapists who do a lot of sport massage treatments, a table with an extra strong top, lightweight foam and durable vinyl is a necessity. If you engage in Reiki or Reflexology, you will need a table with end panels that make it comfortable for you to work on the clients. Shiatsu massage requires a table that can fold so you have a padded surface when you are kneeling. The massage table needs to have a cradle for the head so that clients have a firm soft base for their neck and head when lying on the table. This cradle also needs to be open, so that when clients are lying facedown, they can breathe normally.

Some of the factors you need to consider when buying a massage table include:
* Strength
* Density of the foam
* Durability of the vinyl covering
* Versatility
* Price
* Warranty

You might want to look at some of the accessories you can attach to the table, such as:
* Pregnancy table option
* Arm rests
* Table extenders
* Foot rests
* Carrying case

There are also many different brand names of tables and each of these carry different price tags. If you are just setting up your clinic, remember that the cheapest table is not necessarily the best one for your needs

Auto VIN Decoder - What Do Those Letters & Numbers Mean?

2008-01-30T01:37:00.000-08:00

An Auto VIN Decoder breaks down the unique alphanumeric sequence known as a Vehicle Identification Number, which is a car's fingerprint. Each and every automobile on the road has its own 17-character VIN, and it is this identification number that is used to generate a Vehicle History Report, also known as a VIN check.

The VIN check taps into millions of DMV records and reveals all of the available history for a particular vehicle, including any hidden problems, odometer readings, ownership transfers and more. It is an absolute must for used car buyers, as it tells you everything you need to know about the vehicle.

The Auto VIN Decoder can help you understand what these letters and numbers mean, which is the first step towards ensuring that a vehicle you are considering is right for you.

Let's break down the Vehicle Identification Number, starting with the first character. (Please note the letter "I" as in indigo, the letter "O" as in orange, and the letter "Q" as in queen are NOT found in any VIN Numbers.)

(We will use the following VIN as an example: 2FTRX18W1XCA01212)

The first character represents the country of manufacture, and can be a letter or a number, each signifying a different country. The most common ones are as follows:

(1 = USA, 2 = Canada, 3 = Mexico, J = Japan, K = Korea, W = Germany, Y = Finland, Sweden)

So using the Auto VIN Decoder in the above example, this particular car was made in Canada.

The second/third characters represent the manufacturer, also known as the make. The most common are:

(A = Alfa Romeo, B = Dodge, C = Chrysler, D = Daihatsu, E = Eagle, F= Ford/Eagle, G = All General Motors vehicles (Buick, Cadillac, Chevrolet, Oldsmobile, Pontiac, Saturn) H = Honda/Acura, J= Jeep, L = Lincoln, M = Mitsubishi, N = Nissan/Infiniti, P = Plymouth, S = Subaru, T = Toyota/Lexus, V = Volkswagen)

So using the Auto VIN Decoder in the above example, this car is a Ford or an Eagle..since Eagle is no longer made, it is most likely a Ford.

Other popular makes use a 3-character initial sequence:

(TRU/WAU = Audi, 4US/WBA/WBS = BMW, 2HM/KMH = Hyundai, SAJ = Jaguar, SAL = Land Rover, 1YV/JM1 = Mazda, WDB = Mercedes-Benz, VF3 = Peugeot, WP0 = Porsche, YK1/YS3 = Saab, YV1=Volvo)

The fourth character is the type of restraint system.

In the above example, "R" represents hydraulic breaks using the VIN Decoder.

The fifth, sixth & seventh characters are the vehicle line, series and body style. This will obviously be different across makes and models.

In the above example, characters 5, 6 & 7 are X18: X18 is a Ford F150 Pickup 4WD Super Cab

The eighth character is the engine type.

With the Auto VIN Decoder, W represents a 4.6 liter V-8 engine.

The tenth character represents the year of the car. Pay close attention to this one:

B = 1981 F = 1985 K = 1989 P = 1993 V = 1997 1 = 2001
C = 1982 G = 1986 L = 1990 R = 1994 W = 1998 2 = 2002
D = 1983 H = 1987 M = 1991 S = 1995 X = 1999 3 = 2003
E = 1984 J = 1988 N = 1992 T = 1996 Y = 2000 4 = 2004

For the most recent used model year, 5 = 2005

In the above example, the "X" indicates that this car was made in 1999.

The eleventh character indicates the assembly plant.

In the above example, the C indicates Ontario, Canada

Characters 12-17 represent the vehicle's unique fingerprint. It is these six digits which make every single vehicle in the world different.

So using the Auto VIN Decoder one last time, the Vehicle Identification Number: 2FTRX18W1XCA01212 represents a 1999 Ford F150 Pickup 4WD Super Cab manufactured in Ontario, Canada with hydraulic brakes and a 4.6-liter V-8 engine.

So there you have it, the Auto VIN Decoder. If you are in the market for a used vehicle, use this decoder to make sure that it is indeed the exact model that the seller is claiming it is. Once you have verified the Vehicle Identification Number is accurate, you can proceed with your VIN check and learn everything you need to know about that particular car.

History Of The Lighting Tower

2008-01-07T05:33:00.000-08:00

Who invented the first portable lighting tower?

This depends largely on your definition of a lighting tower. A broad definition could include something as simple as a candle or primitive torch placed on a tall mast to cast light over a large area, such a device has probably been in use since the Stone Age.

In more recent history it’s un-clear as to when the modern lighting tower was invented. Researching patent applications indicates that machines not dissimilar to today’s lighting towers were being designed in the 1930s.

A patent from 1932 shows what might be the first machine of its kind filed in US patent 1934576 and is named as a “Portable floodlighting unit for airports”.

The patent describes a chassis with 4 wheels at each corner (allowing the machine to be towed), a generator powered by an engine and one large electric lamp at each end of the vehicle. The machine is designed to be used to provide on-demand lighting of alternative landing sites at airports on occasions when the main landing areas are out of use because of adverse weather conditions.

More recently in 1980 a US patent 4181929 was filed for a Portable illuminating tower that illustrates a much closer resemblance to modern day lighting towers.

The US patent 4181929 describes a portable lighting tower consisting of a base frame (which contains an engine and generator) and a vertical, extending, hydraulic mast with two electric lamps at the upper end. The unit does not permit towing but instead is lightweight and compact enough to be easily transported. The design also includes jack legs that are now common place on all lighting towers to ensure stability in high winds.

This is quite a significant development in the history of the lighting tower as this patent largely forms the basis of most modern day lighting towers which contain similar elements such as a base that stores the engine and generator along with an extending hydraulic mast that supports the luminaries.

The next patent was filed later in the same year of 1980 but was for a solution to provide more extensive illumination. The US patent 4220981 describes a chassis with 4 wheels to hold the generator and engine and two folding telescopic masts at opposite corners of the chassis that each hold a cluster of electric lamps. The design also allows for the masts to be rotated enabling finer control of the area of illumination. By offering two masts the light tower also allows for illumination over nearly all sides of the machine. This is unlike previous light towers which generally offer illumination on only one side of the machine.

Since 1980 considerable progress has been made by lighting tower manufacturers. Although the overall design has varied little from those seen in the 1980s many improvements have been made to make lighting towers easier to use and more environmentally friendly.

Boat Lift Motors

2008-01-07T05:32:00.000-08:00

Technical support and efficiency are important when purchasing a boatlift, but the most crucial part of a boatlift is the motor. Rather than manually spinning the wheel of a boatlift in order to get the boat on and off the water, a motor makes the job easy on you, and they are not hard to operate. Boatlift motors play a crucial role in saving effort for when you are actually in the water enjoying the boat itself. It is very important to have a good boatlift motor.

Most of the boatlift manufacturers are top providers of quality boatlift motors. Electricity is one of the prime requirements for using motors to enhance one’s job of launching a boat. All one has to do is flip a lever, throw a switch, and let the rechargeable power of the boat's battery or AC power from the shore raise your boat into its storage position. AC or DC, the units are both compact, easily assembled and can be disengaged for manual operation of the lift wheel. Why would you want to disengage and do it yourself? Why, in case of a long-standing power outage, of course.

Boatlift motors are readily available and replaceable for all kinds of pontoon, hydraulic and floating boat lifts. Most of the motors on the market are reasonably priced and fit almost all boatlifts made. They are simple to operate with low maintenance, and they have simple installation procedures. Most motors available on the market give a one-year warranty, but your boatlift should probably last many more years than that.

Angle Roll Bending Machine Information for Buyers

2007-12-19T22:23:00.000-08:00

When it comes to metal fabrication equipment, you may have heard of an angle roll bending machine. Some may refer to it as a section bending machine, but its purpose is still the same - form raw pieces of metal into desired shapes and sizes.

If you have ever seen an angle roll bending machine, you would agree that most are constructed in a vertical steel frame. It is common that the bending portion of the machine is located on one side, with the power and drive of the machine on the opposite side.

This writing is intended to educate and help the purchaser of Angle Bending Machines to ask the right questions when considering a purchase.

Power source:

Small units are powered by an electric motor with a reducer. The power transmission is accomplished by gear trains and or chains / sprockets combinations. These are units used in small job shops and rod iron fabricating establishments. The new generation of the section bending machines is powered by hydraulic systems. These are used for bending from the smallest bars to very large wide flanged structural beams.

The large hydraulic units have a double pump hydraulic system, with one providing the flow for the rotation of the rolls and the other for the extension and retraction of hydraulic cylinders attached to arms carrying the bending rolls.

Some designs use one main hydraulic motor, usually mounted to an epicyclical in-line reduction gear, which imparts rotation to all three rolls. Another variation is each roll having its individual hydraulic motor/ reduction box combination directly driving it.

The Bending Process:

There are some terms used in the industry describing the capacities of Section Bending Machines and the process used, which the purchaser should become familiar with.

Square and rectangular rods, round rods, square and rectangular tubing, round tubing, standard pipe, equal leg and unequal leg angles, "C" and "MC" channel, "S" and "WF" beams, "T" bars …these are sections which can be rolled on section bending machines.

"Leg out" means the leg of a section, like in angles will stick outward from the ring formed in a radial direction. "Leg in" means the leg of a section, like in angles will stick inward from the ring formed in a radial direction toward the center of the ring. "Leg out" is also known as "Easy way" and "Leg in "Hard way" There are exceptions to this terminology when it comes to channels, whereby one can bend a channel leg in, leg out and the hard way when bent on its side.

Bending of round sections, pipes and round tubing require special tooling other than what is usually provided standard with section bending machines. In special cases with square and rectangular tubing where the wall thickness is low…the manufacturer should be consulted as to whether special all section enveloping tooling is required to avoid the section from collapsing under the bending forces.

Bending Channels, S beams and WF beams the hard way, present a special challenge because the force of bending would sometimes collapse the web connecting the flanges. Most manufacturers of heavy section bending machines offer what is called a "Traction Tool", which holds the section back and supports the web so as to avoid collapse.

Machine Capacity:

Each section has what is known as a "Section Modulus". This value is a measure of the resistance a section displays to bending. It is the quotient of the sections Moment of Inertia about the axis passing through its center of gravity, which coincides with the neutral axis of the section and the furthest distance on the section from that neutral axis. In symmetric sections bending about the neutral axis both ways will give the same section modulus, however in non symmetric sections, the section moduli are different for calculations of leg in and leg out bending.

Depending on the design of the machine, each machine will have a certain capacity of bending. Thus the pressure exerted on the machine members will dictate the limit, before rendering the deflections the members sustain unacceptable or the wear and tear caused on the machine would be excessive. This limit is what is specified as W or S (Section Modulus Capacity) in in3 or cm3.

In general catalogs and brochures describing section bending machines would give the maximum section sizes a machine can bend of each type of structural or bar section. With a minimum diameter the machine can bend them to. By rule of thumb and practice it has been established that the minimum diameter of bars, tubes and pipes is ten times the height of the leg or the dimension taken in the radial direction. For the rest of the sections it is approximately 11 to 12 times the height of the section or the leg.

When a section dimension and thickness is not mentioned on the capacity charts, the user either needs to calculate the section modulus of the section and if this is less than the Section modulus capacity of the machine, he/ she will be in the safe zone and no damage will come to the machine. If in doubt it would behoove the user to contact the manufacturer for professional advice.

Controls:

Section bending machines have become sophisticated and are using NC and CNC to bend complicated forms. These controls have canned programs for standard sections and they use teach mode where by the operator can produce the part manually and the machine keeps track of all the steps he/ she uses to accomplish the job. Then the program is memorized and archived for continuous use.

The new controls can even collect their own section characteristic data, by bending a piece of the section at different settings. The radius produced at a certain setting is input into the program and by taking three readings, the program surmises the reaction of the section to bending forces; then uses the information when the program parameters are entered and the part is run…at first trial the machine would produce a near perfect part. With small adjustments, what used to take hours of testing, experimenting and developing is cut down drastically.

Controllers have large memory capacity and many job programs are stored and recalled easily. Most units have RS232 communication capability and lately USB ports have been appearing on most of them. There are many operating systems used on these controllers…some are still using DOS, some use Windows and even Linux, while some have proprietary operating systems.

Observation:

With each passing day, technology is improving, and this is no different for angle roll bending machines. Computers and engineers are largely responsible for section bending machine construction, and this allows for more precise equipment. Some inexperienced shoppers may jump at a machine with greater horsepower or even one that weighs more. Do not be fooled; instead consider these things when buying: reliability and durability of materials used in the machine's construction, solid design, and of course ease of maintenance.

Making a mark in hydraulic cylinders: Parker Hannifin's Intellinder technology designed to bring enhanced precision to hydraulic cylinders in mobile e

2007-07-04T03:14:00.000-07:00

With the integration of electronics and advanced CAN-Bus controls, mobile hydraulic systems and components have gotten a lot more intelligent. But one of the areas that has lagged a bit has been hydraulic cylinders. One of the "muscle groups" of hydraulics, cylinders are used for a variety of functions on a machine, including steering, lifting and lowering, etc.

A key factor in the successful adaptation of advanced controls is understanding where a specific component is at a given time. To precisely control a cylinder, step one is understanding where that cylinder is in its stroke at a given time. There are ways to do that--LVDTs or magnostrictive probes, for example--but these can have some significant drawbacks in mobile machinery. In an effort to overcome some of those drawbacks and add some intelligence to cylinders, Parker Hannifin is working on a photo-optical position feedback system that can be incorporated into hydraulic and pneumatic cylinders, as well as other linear actuators. A prototype of the Intellinder technology has been adapted to a telehandler that will be on display at the company's booth at the ICUEE show in Louisville, Ky.

The Intellinder system is designed to be part of a fully functional electrohydraulic circuit controlled by Parker's IQAN CAN-Bus control systems. Unlike conventional position sensing systems, no movement is required to acquire the precise position of the actuator. Instead, the system is able to sense the position optically, through a combination of an innovative marking system and the use of an external fiberoptic sensor.

"The more commonly used technology for position sensing is to have a probe-mounted device," said Ulrich Neumann, chief engineer, product development at Parker's Mobile Cylinder Division. "Using a probe-mounted device means that the cylinder rod or the piston rod has to be gun drilled. That's not really practical in the mobile hydraulics industry.

"There are other devices that have been used, flexible probes and things like that, but the difficulty is you always end up with an additional leak path. If your probe is mounted internally, you need to get cables in or out, either to get the information or to power the probe.

"The idea we had was to come up with something different. Rather than add something to the cylinder, what we wanted to do is try to make part of the cylinder the scale itself. The rod lends itself wonderfully to that."

The key to the technology is a proprietary marking system that discolors the chrome rod surface. "Our process does not disturb the surface of the rod," said Neumann. It's basically imprinting markings on the road and if you feel it, there are no surface undulations."

In the rod used in the telehandler's steering system, the surface marking appears as a series of dark rings, which are read by a fiberoptic sensor mounted on the side of the cylinder.

The technology is scalable and can be used in cylinders with strokes as long as 23 ft., and multiple sensors can be mounted around the rod to provide double or triple redundancy. The resolution of the optical system is well within mobile equipment industry standards and there is no deadband on either end of the sensing range, the company said, along with no measurable hysterisis. It is also fully ruggedized for application in mobile equipment, according to Parker.

The Intellinder system is in the initial phases of commercialization of the technology, having completed lab testing under a variety of conditions such as temperature, vibration, shock, contamination, EMF and EMP. The system is currently in selected prototype machine applications.

The prototype telehandler provides a good glimpse of what the future might hold, however, as the Intellinder system is used to provide a steer-by-wire system, as well as provide programmable lifting functions.

"In a forklift or telehandler, a vertical lift is a combination of raising the boom and moving the boom out in order to keep the load on a vertical path," noted Neumann. "You have to superimpose the two motions and the rate constantly changes. It takes a lot of skill to do it.

"With this system, you can write a simple lifting program that will tell the machine to lift a load vertically from the ground to however high the machine goes and the controller would literally meter out and perform a perfect vertical lift.

Durst introduces all-new hydraulic pump drive line; newly designed range consolidates three lines into one; modular design commonality throughout; foc

2007-06-19T00:56:00.003-07:00

The Durst Division of Regal-Beloit Corp. is introducing a completely new line of hydraulic pump drives intended for a wide range of mobile off-highway applications. The company has built hydraulic pump drives under the Regal, Federal and Terrell brand names, a range that over the years through development and acquisition, had grown to 22 models and myriad part numbers and configurations.

This completely new line, which will be sold under the Durst brand urine, is comprised of nine models covering horsepower ratings from 495 hp to 1025 hp.

There are four product groups within the new Durst line. The smallest, rated 495 hp at 2500 rpm, includes one-, two- and three pad drives with 6 in. and 6.5 in. gear centers. Above that is a family of 8 in. gear centers, two-, three- and four-pad models rated 725 hp at 2500 rpm. Next is a two- and three-pad family with 10.5 in. centers rated 950 hp at 2500 rpm. The largest pump drive in the new family is a 11.33 in., four-pad modal rated 1025 hp at 2500 rpm. An accompanying table includes more complete details, including ratios.

Durst is retaining a pair of smaller 460 hp direct-drive single-pump drives and a large six-pump drive model rated 600 hp. All of the new models and the existing models will be built at Durst's Shopiere, Wis., manufacturing operations which have recently been redesigned and expanded to manufacture the new pump drives.

The 6/6.5 in and 8 in. center drives will be available on April 1, with the 10.5 in. and 11.33 in. center models due by July 1. The other existing models will be phased out as the new models are introduced.

All are targeted at a wide range of global off-highway machines. In the construction markets this includes paving and compaction equipment, and hydraulic cranes; municipal applications such as sweepers, snow removal machines, in forestry, timber harvesting and processing equipment, as well as chippers and shredders.

Other potential applications include railway maintenance equipment, specialty ag equipment, ag sprayers, oilfield drilling and exploration equipment, including offshore, as well as workboats.

Overall this redesign program led to reducing 22 models to 12 modular drives, with simplicity being the key to the project from day one.

"This is an incredibly standardized product; gears, bearings, seals; the output groups, the input groups are all common in every model," said John Phillips, sales and marketing manager at Durst. "This is design for manufactability taken to the fullest extent possible." Further, the footprint of the new drives is interchangeable with Durst's former lines as well as competitive models.

"Cost and availability were the keys as we looked towards creating this new pump drive line," said Sam Finocchio, Durst's engineering project manager. "We wanted to come up with something that created common geometry across the different models, so we could have fewer parts and provide volume opportunities for manufacturing.

"That led us towards spur gears, ball bearings, all of which eliminate the time required for shimming, which at one time accounted for 50-60% of our assembly labor, especially on the larger models."

What resulted is an impressive new line that starts with modular design in which the bearings and gears are self contained within cast iron split housings. Input and output adapters are not required to retain the bearings, Finocchio said, and input and output adapters can be added or changed any time prior to installing the unit.

This, Phillips and Finocchio said, leads to greater flexibility for both distributors and equipment manufacturers. "We can sell these to a distributor as a module; housing and gears," Phillips said. "The distributor can stock pump adapters, engine adapters and drive plates and assemble a unit as a specific application dictates. If an OEM changes pumps or pump specs, the manufacturer or the distributor, now has more flexibility to make those changes."

The new Durst hydraulic pump drives all me AGMA Class 10 gears throughout, which Finocchio said are as quiet as helical gears. The drives include a solid-on-shaft, one-piece gear/shaft design that Finocchio said provides consistent and uniform alignment with bearings pressed on the gears, simplifying assembly. There are 31 gears that are totally interchangeable across the different models.

Torque Transducers suit aerospace hydraulic pumps/motors

2007-06-18T23:17:00.002-07:00

September 9, 2005, Depew, NY, USA - Rotating torque transducers from the Force/Torque Division of PCB Piezotronics, Inc. (PCB[R]), utilize non-contact, rotary transformers for sending excitation voltage to, and receiving measurement signals from, the strain gage instrumented rotating sensor element. The rotary transformer design eliminates the need for replacing worn brushes, as is the case with conventional slip ring type rotating torque sensors.

Because of their unique flange and splined shaft design (conforms to AND 10262 & 20002), the units are an ideal choice for use in torque studies on cantilevered aerospace hydraulic motors and pumps. Other applications include dynamometers for combustion engines, drive shafts, transmissions, fans, and electric motors.

In addition to the torque output signal, an optional pickup provides an output proportional to speed and an optional K type thermal couple to monitor internal bearing temperature. The units feature high torsional stiffness and low rotating inertia. Custom designed units are available for alternate measurement ranges and speeds.

The evolution of Parker's hydraulic fan drive systems

2007-06-07T03:01:00.001-07:00

There are also several additional complications. Engines must operate in a relatively narrow temperature range to meet the emissions levels, yet off-highway engines typically operate in the broadest range of climates imaginable, from desert heat to arctic cold. Along with basic engine cooling, there is also a growing number of other cooling loads to be dealt with--engine and hydraulic oil cooling, air conditioning refrigerant, charge-air cooling, transmission cooling, etc. These increased cooling loads must be accommodated in the same, or often less, space in the engine compartment. Finally, there are the traditional requirements of cost and reliability that must at the very least be maintained.

To address this list of challenges, one technology that has received increasing attention has been hydraulic fan drive systems. An alternative to traditional engine-mounted, belt-driven fans, hydraulic fan drive systems have evolved over the last decade from relatively simple on/off systems into sophisticated, digitally controlled units that provide several operating and packing advantages.

Perhaps the primary benefit of hydraulic cooling systems is their ability to control fan speed independent of engine speed, which allows the fan to be operated at the precise rpm needed to accommodate the thermal load at any given part of the operating cycle. This is critical in terms of overall cooling efficiency and engine fuel economy, as typical belt-drive systems can consume as much as 10% of engine horsepower.

Mature Colombian field improved with dual stimulation: a combination of acid and propped fracturing technologies generated a significant increase in p

2007-06-07T03:00:00.000-07:00

olombia's Orito field has operated for more than 35 years. By this decade, it had seen production decline to less than 3,500 bopd from a one-time peak of 66,000 bopd. Recently, Petrominerales achieved a significant increase in production and recoverable reserves by using a dual stimulation service that combines acid and propped fracturing technologies.

The treatment was successfully used in a reservoir that has frequently failed to respond to hydraulic fracturing, and where a 2002 third-party reservoir study concluded that the wells "indicate higher skin factors following the fracture treatment and lower production ratios, regardless of the fluid used." The service is designed to remove fracture face skin and optimize fracture conductivity.

ORITO FIELD AND CABALLOS FORMATION

Orito field, almost 17 [mi.sup.2] (43 [km.sup.2]) in area, is in Colombia's Putumayo basin, Fig. 1. As the basin's largest field, it originally contained more than 1 billion bbl of oil-in-place, in three primary reservoirs. The most significant is the Cretaceous Caballos formation, a complex series of fluvial/deltaic and marginal marine sands that originally contained more than 700 million bbl of oil-in-place, Fig. 2. The Caballos zone, alone, has produced 186.7 million bbl since the field was discovered in 1963. By 2005, the reservoirs had cumulatively produced 226 million bbl, or about 22% of original

The evolution of Parker's hydraulic fan drive systems

2007-06-02T03:07:00.001-07:00

One of the more challenging side effects of today's engine emissions technology is that the new engines generate more heat than their predecessors. That trend will accelerate in Tier 3 and later Tier 4.

There are also several additional complications. Engines must operate in a relatively narrow temperature range to meet the emissions levels, yet off-highway engines typically operate in the broadest range of climates imaginable, from desert heat to arctic cold. Along with basic engine cooling, there is also a growing number of other cooling loads to be dealt with--engine and hydraulic oil cooling, air conditioning refrigerant, charge-air cooling, transmission cooling, etc. These increased cooling loads must be accommodated in the same, or often less, space in the engine compartment. Finally, there are the traditional requirements of cost and reliability that must at the very least be maintained.

To address this list of challenges, one technology that has received increasing attention has been hydraulic fan drive systems. An alternative to traditional engine-mounted, belt-driven fans, hydraulic fan drive systems have evolved over the last decade from relatively simple on/off systems into sophisticated, digitally controlled units that provide several operating and packing advantages.

Perhaps the primary benefit of hydraulic cooling systems is their ability to control fan speed independent of engine speed, which allows the fan to be operated at the precise rpm needed to accommodate the thermal load at any given part of the operating cycle. This is critical in terms of overall cooling efficiency and engine fuel economy, as typical belt-drive systems can consume as much as 10% of engine horsepower.

"Cooling system designers are beginning to recognize that the major advantage of de-coupling the cooling fan from the engine shaft or pulley system is not the ability to place the radiator virtually anywhere, or move the cooling pack away from the engine to gain easy access," said Gary Gotting, global industry market manager, fan drives for Parker Hannifin's Mobile Division. "The critical facts are that a de-coupled system is the only way to achieve higher cooling rates at low engine speeds and the only practical way to achieve cooling on demand which, during 'ram air' operation saves fuel, cuts both emissions and noise generation and flees up engine horsepower to increase productivity.

"We are seeing today that a single multi-path radiator very often is used to cool multiple fluids," Gotting added. "A traditional direct-drive fan system lacks the flexibility and controllability to accomplish all of these tasks efficiently, because its performance is almost entirely determined by engine speed. And with the traditional approach, engine speed and cooling load are not generally well coordinated, with the result that a lot of fuel is wasted turning a fan at much higher speeds than necessary.

"For example, if more cooling is required at idle due to high ambient temperatures, the only way to obtain it is to increase engine speed. But, running the engine faster only adds to the thermal load on the system while increasing fuel consumption and exhaust emissions. At the other end of the spectrum, no fan-induced airflow may be needed when a vehicle is in motion, but the direct-drive fan will continue to consume engine power and waste fuel.'

The fan drive systems produced by Parker Hannifin's Mobile Division for large and midsize diesels used in both on- and off-highway applications utilize a digital controller to monitor system conditions and adjust fan speed accordingly. At the heart of the system is a Parker IQAN controller in one of two basic configurations.

Depending on application requirements, an IQAN TOCB may be used to communicate with other on-board systems via an industry standard J1939 communications Bus and integrate multiple functions such as engine and transmission temperature control. Or a simpler IQAN MDM or MDL model may be used to monitor inputs from temperature sensors in the various cooling loops and intelligently adjust fan speed as necessary to keep all systems within programmable limits.

Parker also offers other controllers, both digital and simple analog, designed to give users flexibility for retrofit or vehicle upgrades. Some of these can be directly connected to engine electronic control units and provide options including purge or fan reverse and visual diagnostics with data logging. These controllers are encapsulated in a flameproof epoxy block and ruggedized for mounting within the engine compartment or other exposed location. They are EMC compliant to EN-12895-2000 (Industrial Truck) and EN-50081-1 and EN-50082-2 (Heavy Industrial) standards, fully electrically isolated, and protected against damage from I/O shorts, opens and reverse connections, the company said.

Because fan operation is now fully programmable, a broad range of features intended to improve efficiency can be included. Examples are accelerated warm-up with the fan deactivated; "on delays," which remove tan load during hot starts; and automated and/or on-demand purge or reverse airflow through the radiator to blow out dirt and debris.

Rotary actuators deliver uniform torque

2007-05-01T02:49:00.000-07:00

The hydraulic cylinder Division of Parker Hannifin has launched its latest range of HTR rack and pinion rotary actuators. The latest HTR actuators are designed to improve the performance and operational flexibility of a wide variety of loading and handling systems in the factory automation, process, construction and marine sectors.

The robust HTR actuators use proven tie rod cylinder technology, with cylinder pistons mounted on each end of a hardened steel toothed rack which engages with a rotary pinion shaft set at 90 degrees to the direction of piston stroke.

The complete unit is durable, with a housing manufactured from hardened alloy steel.

Just as importantly, all mechanical components are completely enclosed, making it safe to use and, unlike competing cylinder and crank arrangements, free of potential pinch points.

The standard range of HTR actuators can be supplied with pinion shafts capable of rotating through 90, 180, and 360-degree angles, while custom versions are available for any range of movement up to five full revolutions.

All models deliver uniform torque in both directions, ensuring high levels of motion control and performance.

Simple yet robust, the rack can be pre-loaded to eliminate the effects of backlash, providing excellent positional accuracy and repeatability.

Internal cushions are available to provide progressive deceleration, protecting machinery and materials from end of stroke impacts and reducing noise.

The cylinder piston is protected by polyurethane seals and PTFE O-rings, providing excellent sealing properties with minimal friction to reduce stiction and break away forces.

All HTR rotary actuators feature a drive pinion which is supported by large-capacity roller bearings, enabling each unit to accommodate high external radial and thrust loads, often avoiding the need for separate support bearings with corresponding cost and space savings.

The latest HTR rotary actuators are also available in double-rack versions, for high-torque applications up to 68,000Nm.

Seal kit repairs - will

2007-05-01T02:48:00.000-07:00

Many people believe if they just fit a seal kit in their unit it will solve all their hydraulic downtime problems. Although there are some occasions where a seal kit only repair is required, usually you will find there is another reason for your seal kit failure. The most common reasons for your seal kit to harden is purely age and heat - this causes the modular strands to vulcanise, leading to a hard inflexible seal.

Some other common reasons include: high case pressure, bearing failure and excessive heat to the unit.

Any of these faults can cause damage to the rest of your unit and can end up being very costly if not resolved.

As above the main reason to avoid a seal kit only repair is the fact that nine times out of ten there will be an underlying cause for the leak and avoiding getting your unit properly inspected and repaired will only end up costing you more in the long run.

As you may or may not know if you do send a unit in to your hydraulics company for a reseal it is not uncommon for other components found to be damaged in the process and these will need replacing, the most common item found to be damaged in this process is the bearings as they fit so closely to the seal kit.

A pump develops a leak - but why?.

At Hydraulic Pumps (UK) we get many phone calls from customers requesting a reseal as their unit is leaking.

Through experience we have learned this is usually not just caused by the seal kit.

Over 90% of seals in pumps and motors are static, in that neither face they seal to move.

Shaft seals are the most obvious exception is the shaft seal.

If an old seal will still do its job there must be another reason for it to leak - the most likely reason is an increase in case pressure.

So what can cause this increase in pressure?.

The simple answer is internal wear leading to a loss of performance and high internal leakage: fitting new seals may seal the leak in the short term but it will soon return.

Another contributing factor is a restricted case line: this will cause a high case pressure, not only will the seals be damaged but further damage may be done to the main rotating parts of the pump leading to a major failure.

What can I class as a major failure?.

If your unit has suffered catastrophic failure oil will pulse into the case creating a pressure spike that cannot be accommodated by the drain line.

The next weakest point will often give way, usually a body seal or shaft seal.

So what if my shaft seal fails?.

A hard shaft seal will wear the metal of a rotating shaft producing a grove which, due to the loss of flexibility cannot be taken up by the seal.

In this case a replacement seal will only be damaged by the worn shaft, only lasting a short time.

In all the cases above a leak is only due to a further deeper problem developing.

A quick reseal should only be seen as a short term stop gap solution, while the underlying problem often remains.

Only a full service by qualified personnel will return the unit to its original condition.

So why do old seal kits still seal?.

Even as they harden seals retain the form into which they were originally squeezed when the pump/motor/valve was assembled.

Our experience is that seals of a great age (the shelf life of the average seal kit is 12-15 years) can still function as long as they remain undisturbed.

It is only in removing them that the problems begin.

Having hardened they are inflexible process of removal and refitting if hard enough they will often fracture on removal.

Even softer seals are prone to damage on removal.

It is recommended that if a hydraulic unit is dismantled a new seal if fitted It is advisable to get your unit checked out for any faults after roughly 3000 - 5000 hours of use.

So when is it advisable to reseal only?.

It has been advised that a professional hydraulics company would only advice just a reseal in the following circumstances.

If the rest of the unit looks new and unmarked or if other components can be recovered solely by machining/lapping.

Please note: when deciding if just a quick fix if really worth it you should also be aware most reputable hydraulics company will not offer a warranty on a reseal.

So to seal or not to seal - you decide.

System monitors oil tanks

2007-05-01T02:47:00.002-07:00

Parker Hannifin has introduced an innovative monitoring system for use with hydraulic and lubricating oil tanks. The SensoControl OilTankController (SCOTC) is believed to be the first of its kind to offer multiple sensing and monitoring options in a single, compact device, which is quick and simple to install, use and maintain, and is available at a competitive cost.

To date, oil tank monitoring has generally required separate temperature and level controllers, plus independent filler nozzles and air filters.

Installing and maintaining individual units is both time consuming and relatively costly; additionally, multiple entry points and extra connections are required for each tank, with individual units also taking up considerable space on the side or top of the tank.

By comparison, the latest SCOTC combines temperature and level controllers with a standard filler coupling and a standard venting filter in a single, integrated device.

This requires just one DIN standard entry port to be made in the tank and can typically be fitted and connected in less time than is required for traditional units.

The SCOTC has a robust aluminium construction, with the head unit integrating the venting filter, filler coupling and, depending on specification, either single or twin LCD displays; these can be configured on-site and also incorporate analogue output connections for remote control or monitoring.

In addition, the SCOTC has a built-in sensor probe and filling tube, with the latter featuring an anti-swirl device to prevent excess disturbance to the tank contents during refilling.

The pre-installed temperature, level or pressure sensors use proven technology and are reliable and accurate, producing consistent results under a wide range of operating conditions.

Reputable repair company

2007-05-01T02:47:00.001-07:00

Repairing hydraulics can be a costly business but getting it wrong can be extremely frustrating, time wasting and expensive. There are six key questions to consider: Are they registered to an industry body? Do they provide a good warranty? Are there any hidden extras and costs? Can they provide 3rd party referrals?

Are they an authorised repair centre?

Do you receive a test certificate?.

The BFPA/BFPDA is a body in our industry that encourages quality assurance within the hydraulics industry as a whole.It ensures that other members conform to a published code of professional conduct.

Other registered bodies that may help you as the customer are industry specific ones such as: Link Up, Apex, EEF etc.

With a new unit you can expect to receive a 6-12 month warranty.

A reputable repair company will give you that on a repair too.

Ensure you have a minimum 6 month warranty or even better; go with a company that provides a 12 month warranty with a shelf life included.

Make sure you are clear what this warranty covers beforehand.

A common phrase is 'free collect, inspect and quote service', but what if you don't want your unit repaired?.

What if the unit is beyond economical repair?.

It is always good to find out what the hidden charges are and to make sure you don't have to commit to a repair just because the quote was free.

A reputable repair company will tell you of the costs involved from the beginning and will not shy away from this.

You should be able to view or ask to view referrals from previous customers on their experience with the repair company.

A good indication of a reputable company is one that has a distributorship/authorised repair centre for a leading manufacturer.

If a company does not boast distributorship then make sure it uses genuine spares in its repairs: that way you know it is trustworthy and you are likely to get a long lasting repair.

Not all customers want a test certificate: however; it is worth knowing if you can have a test certificate if you want one.

You will then be able to see that your unit has been tested thoroughly.

Generally you can trust your instincts on this topic but it's always good to go in with a few questions before sending your unit off.

If you are going to pay for a repair you might as well ensure it's with a trustworthy and reputable company.

Knowing your gear pump

2007-05-01T02:46:00.001-07:00

Making an informed decision can be so much easier when you understand the basics of what a gear pumps is and how it works. A gear pump uses gears to pump fluid by displacement. They are one of the most common types of pumps used for hydraulic applications. Gear pumps however are also used in chemical installations to pump fluid with a certain viscosity.

There are two main types: external gear pumps, which use two external spur gears; and internal gear pumps, which use an external and an internal spur gear.

Gear pumps are fixed displacement, meaning they pump a constant amount of fluid.

Some gear pumps can be made to use either as a pump or a motor.

Powell to put her feet up
Hydraulic Pumps (UK) says farewell and a happy retirement to its Business Development Manager

Hydraulic cylinders rebuilt to original specs
Many hydraulic cylinders are economically repairable, offering the customer significant savings on purchasing a new replacement product from the original manufacturer

The gears inside your pump rotate and separate, on the intake side of the pump, creating a suction which is filled by oil.

The oil is carried by the gears to the discharge side of the pump, where the gears displace the oil.

The mechanical clearances are small, on the order of a thousandth of an inch.

The tight clearances, along with the speed of the rotation, effectively prevent the oil from leaking backwards.

The rigid design of the gears and housing allow for very large range of pressure and the ability to pump highly vicious fluids.

Although anything can be repaired, thanks to the high price of OEM spares and competitive pricing of pumps, gear pumps and motors are not repairable in a cost effective manner.

This can be the same for some obsolete pumps if a cheap replacement can be found.

Any reputable hydraulics company will advise you of this on first contact.

The information most companies will ask you for is as follows: make, model number and serial number.

However, if you do not know this information do not panic - there is a way you can spec up your own gear pump, here is a rough guide to what you will need to know: the shaft type and size (eg splined or keyed, how many splines); the mounting flange type and dimensions (bolt hole diameter and spigot dimensions); the port type and dimensions (eg pitch centre diameter of port fittings PCDs); the flow requirement at 1450rev/min; the working pressure; whether you need a multiple or single pump; and the port inlets and outlets.

If you are unable to measure these data yourself a reputable hydraulics company should be able to do this for you.

Powell to put her feet up

2007-05-01T02:45:00.000-07:00

Moe Powell, Business development manager of Hydraulic Pumps (UK), has reached the ripe old age of 60 and after 12 years with the company has decided to 'put her feet up' and enjoy her retirement. All her colleagues reckon Powell has been a great asset to the company over the years and will be greatly missed but she has promised to stay in touch.

However, all is not lost: the company still has Pam Sharp as General Manager, John Dunn as National Sales Manager and Candice Link as Marketing Manager who will be only too pleased to discuss future requirements with customers.

Hydraulic applications are complex

2007-04-16T22:44:00.001-07:00

Enerpac has come to the aid of the Beijing Olympics with hydraulic solutions contributing to the raising of the stadium roof.

After two years of construction, the main venue for the 2008 Beijing Olympic Games came to a final and most important part of the construction of its steel structure: the dismantling of the temporary support towers. When presenting their stadium design to the Chinese jury, the Swiss architects Herzog and Meuron used the analogy of a bird's nest. Everyone loved the idea of a bird's nest and so they won.

Perhaps because of the culinary association; in China, a bird's nest is very expensive and believed to be extremely healthy, something you eat on very special occasions.

During construction, the crisscrossed interwoven steel roof construction of the bird's nest roof was supported by 78 temporary steel columns.

For additional stability, the huge 'twigs' were welded onto the supports.

After completion of the bird's nets construction the 'twigs' had to be cut off the support piers, before dismantling of the piers could start In most western countries, cranes would have been hired to do the lifting job while welders would cut off the welds off the 78 supports laid during construction.

However, due to the extreme high cost of hiring a number of 800-ton cranes for several days in China, a smarter and less expensive solution needed to be found.

Key pre-requisites to the entire cutting-operation were safety, control, stability and cost.

Enerpac, known from many complex hydraulic applications around the globe and in the Chinese market especially for their hydraulic solutions for moving roofs (NanTong stadium) and moving structures (Shanghai concert hall) was consulted.

Basically the disconnecting and dismantling process of the temporary supports comes down to synchronically and fully controlled lifting the structure of its supports, cutting the welds, followed by controlled and synchronized stage-lowering to allow the removal of the 50mm think leveling plates that were used during construction.

Computer-controlled hydraulics is the perfect match for jobs like this, and Enerpac was granted the contract to perform the stage lifting and lowering of the roof.

The entire configuration including the central computer, satellite computer-controllers, 156 double-acting high-pressure hydraulic cylinders and 55 electronically controlled hydraulic power units was specified and custom designed by Enerpac.

For added safety, control and accuracy, multi-functional valves, load sensors, stroke sensors, shift detection and a digital feedback system were integrated.

The design of the bird's nest is based on three construction circles; an outer circle, a central circle and an inner circle.

Each circle has a specific number of supporting piers, varying from 24 for the outer and central circles and 30 for the inner circle.

For load, control and accuracy reasons the 78 support points including their hydraulic systems are divided into 10 regions, each of which with its own satellite controller.

For the actual stage lifting and lowering process each support pier is equipped with two 150-ton double-acting cylinders.

At the central computer all load and stroke data are pre-programmed for a fully controlled lifting and lowering process.

During the stage lowering process the bird's nest is alternatively supported by the hydraulic cylinders and the leveling plates on the temporary supports.

After successful disconnecting the 45.000 ton steel structure from its temporary support piers, last year November, the bird's nest stood on its own 'feet' for the first time.

Stadium key facts: Start of construction - Dec 2003, Roof completion - Oct 2006, Stadium completion - End of 2007, Gross floor area - 258.000 square meters, Seat capacity - 80.000 (11.000 temporary seats will be added after the 2008 Olympics, Structure - 36km of unwrapped steel length, Height - 69,2m above pitch levels.

Heavy duty tie rod cylinders in catalogue

2007-04-16T22:34:00.000-07:00

Parker Hannifin, supplier of motion and control technology, has released a catalogue detailing the features and specifications of its 2H Series hydraulic cylinders. The heavy duty cylinders incorporate a number of features such as tie rod construction enabling them to offer outstandingly long and efficient service life under high working pressures. Parker hydraulic cylinders offer a compact and cost effective method of moving, positioning or clamping tools or work-pieces in a variety of industrial applications, ranging from automation and machine tool systems, to presses, injection moulding and die casting machines.

The heavy duty 2H Series incorporates a number of innovative features, designed to improve overall performance and reliability, while extending operating life.

The cylinders' piston rods are manufactured from precision ground, high tensile carbon alloy steel, hard chrome plated and polished, to eliminate the problems caused by impact damage, scratches and abrasions which result in shortened gland seal life.

Similarly, the steel cylinder body tube is surface finished to minimise internal friction and wear, prolonging the life of piston seals.

The cylinders feature pressure-energised body seals to ensure that leakage is prevented even under pressure shock conditions.

As well as lipseals manufactured from an enhanced polyurethane, with a life of up to five times that of traditional materials, the piston rods also feature a double lip wiperseal that prevents the ingress of dirt into the cylinder and as a result extends the life of gland and seals.

2H tie rod cylinders are available in a range of bore sizes and stroke lengths, and are able to withstand working pressures of up to 210 bar.

Optional features include end-of-stroke cushioning for controlled piston deceleration, bespoke rod and port sizes, stroke limiters for use where absolute precision in stroke length is required, and rod locking devices providing fail-safe operation.

The 2H Series catalogue is now available, detailing these features in depth and listing the properties (including dimensions, and mass and nominal force) of the entire product range.

Suction and return filter reduces disposal cost

2007-04-16T22:33:00.001-07:00

The SRL1 suction and return filter from Parker Hannifin is available with Parker's patented LEIF elements, which reduce disposal costs by over 50% due to their environmentally-friendly design.

The SRL1 suction and return filter from the Hydraulic Filtration Division Europe of Parker Hannifin, manufacturer of motion and control technology, is available with Parker's patented LEIF (Low Environmental Impact Filter) elements, which reduces disposal costs by over 50% due to their environmentally-friendly design. The SR1 is the most compact suction and return filter in its class, developed for mobile hydraulic applications where space restrictions apply. Parker's SR1 filter is a tank top mounted return filter capable of feeding filtered oil under positive pressure to the suction side of the boost pump, thereby filtering both open and closed loop oil systems through one filter.

This, together with the filter's compact dimensions, makes it a cost effective option for use with mobile equipment requiring both open and closed loop hydraulic circuits, from road sweepers to fork lift trucks.

By incorporating Parker's LEIF elements, the filter is made even more cost effective, as the elements' metal sleeves can be re-used leaving just the contaminated filter media to be disposed of as chemical waste.

The media is small and lightweight, and oil can be simply removed from the element, resulting in an even lower weight and volume, reducing disposal costs further.

Because the LEIF element is a patented design, the quality of filtration is guaranteed, avoiding the problems associated with pirate type products with unknown quality filter media.

The SR1 filter is capable of handling a return line flow capacity of up to 130 l/min and also includes a number of innovative features designed to increase efficiency and enable the problems associated with some suction and return filters from other brands to be avoided.

These features include a bypass valve in series with a back-pressure valve to minimise the risk of cavitation, an improved flow capacity emergency suction valve fitted as standard, and no direct bypass in the tank to remove the problem of oil foaming.

Software control of mobile hydraulic equipment

2007-04-16T22:32:00.000-07:00

The IQAN-MD3 master module is the latest addition to Parker Hannifin's IQAN integrated software-based control system, for more effective design and control of mobile hydraulic equipment.

Parker Hannifin, supplier of motion and control technology, has launched the IQAN-MD3 master module, the latest addition to its IQAN integrated software-based control system, which makes more effective design and control of mobile hydraulic equipment both simple and cost effective. The IQAN-MD3 master module incorporates powerful computing capacity with high processing speeds and dual CAN bus interfaces, which make the unit extremely flexible, able to be used in a variety of applications and with a range of hydraulic components and input devices such as joysticks, pedals and sensors. The unit is extremely robust, able to withstand aggressive conditions during outdoor use and installation, including EMI, vibrations and a wide temperature range, and features a compact ergonomic design making it ideal for use where space is limited.

The 3.5' transflective colour display is an intuitive interface that is easy to customise, making it possible to reduce costs by minimising the need for external instrumentation.

The IQAN-MD3 is programmed using the latest 32-bit software platform IQANdesign, a user friendly tool that allows system level engineers quickly and easily to write machine functionalities and display tools without any specialised programming skills.

This offers manufacturers significant savings in development costs by reducing the time and skills needed to programme the system, and ultimately resulting in a quick return on investment.

In addition to IQANdesign, the IQAN-MD3 also interfaces with IQANrun software, which allows field service technicians to diagnose problems and carry out maintenance using an easy to use graphical interface.

Zinc-nickel coating offers less corrosion

2007-04-16T22:31:00.000-07:00

Stauff has abandoned traditional Zinc and yellow chromating (A3C) plating in favour of the more environmentally-friendly alternative Zinc-Nickel coating and passivation.

Walter Stauffenberg (Stauff) - manufacturers of hydraulic components and accessories, has made the decision to abandon the use of the traditional plating method of Zinc and yellow chromating (A3C) in favour of the alternative Zinc-Nickel coating and passivation. It has been known for some years that the yellow chromating of the surface contains hexavalent chromium. Hexavalent chromium, or chromium (VI) for short, is classed as carcinogenic and can cause allergies in case of direct contact.

The reason behind this development that is still ongoing to this day is the EU Directive on End-of-Life-Vehicles and the RoHS Directive.

These directives govern the disposal and recycling and, as such, the use of hexavalent chromium.

A part of these bans has already been imposed in recent years; the exception applying to the use of chromium (VI) in anticorrosive coatings being due to expire on 1 July 2007.

Whilst Stauff products are not directly affected by this situation, the decision was made to pursue use of the alternative for both environmental reasons and also importantly to provide real additional corrosion protection.

The performance of Zinc Nickel coating + passivation is far superior to the current and common alternatives.

Testing to DIN EN ISO 9227 Salt Spray shows significant improvements : White rust resistance X 4 Red rust resistance X 3.

The customer benefits of this more expensive manufacturing option have been an important part in the decision for Stauff to adopt Zinc Nickel + passivation and sealing for all products.

Hydraulic and pneumatic components for Michelin

2007-03-27T04:26:00.001-07:00

Parker Hannifin products were specified as a single source of hydraulic and pneumatic components by Michelin for its tyre plant in Olsztyn, Poland.

With international demand for vehicle tyres heading towards one billion euro mark per annum, competition is tough, and companies such as Michelin are constantly striving to improve productivity and efficiency and respond to the expectations of vehicle manufacturers and consumers in terms of safety, respect for the environment, price, comfort, and ergonomics. When new investment was planned for their plant in Olsztyn, Poland, Michelin wanted to ensure that all materials, machinery (and components therein) would contribute to these objectives, which meant reliability, quality, low maintenance and cost-effective running. As part of this programme machine builder Harburg Freudenberg Maschinenbau was chosen to provide tyre curing presses on a multi year period, and in turn, Parker Hannifin products were specified as a single source of hydraulic and pneumatic components because of their expertise, and proven record of accomplishment within previous projects with both Michelin and Harburg Freudenberg.

The curing process is where tyres get their final shape and tread pattern.

Hot moulds shape and vulcanize the tyre.

The moulds are engraved with the tread pattern, the sidewall markings of the manufacturer, and others required by law.

Tyres are cured at about 300 degF for 12 to 25 minutes, depending on their size, and are then 'popped' from their moulds, taken to final finish and inspection.

The demanding specification for the curing presses and the hydraulic and pneumatic components therein was drawn up by Michelin, and was exact, calling for quick start-up, precise positioning, cost savings, high efficiency, low maintenance, and, with future projects in mind, world-wide service support.

Working alongside other Parker European divisions (France and Germany) Parker Poland co-ordinated all specifications, drawing up the project plan and liaising with all parties concerned, proving the benefits of local support, service (and availability of parts), and have been on-call during the development, production and commissioning stages, even providing tailor-made components, via Parker manufacturing plants in Germany.

Products include hydraulic control units, power units, hydraulic cylinders, sensor, and valves, together with pneumatic connectors, hoses, and couplings.

The column type presses incorporated customised hydraulic roundline cylinders from Parker.

The rod and piston assemblies being fatigue free at full rated pressure, and seals housed in corrosion-resistant steel glands which provide retention of pressurised fluid while preventing the ingress of contaminants.

The heavy duty polymer bearing rings resist side loadings, and the wide separation of these rings reduces bearing stresses, extending the service life of the bearing itself.

Together with a high surface finish to the high density wall steel tubing to minimise internal friction and prolong seal life; cushions at the head and cap provide controlled deceleration reducing noise and shock loading extending machine life; these cylinders will give exceptional service in any rugged, tough, high demanding environment.

Maintenance is simple and easy with the rod bearing and rod seal being replaceable without completely dismantling the cylinder - and in the event of an emergency the flanges are spaced away from the head and cap to allow the bolts to be sawn through quickly.

Hydraulic proportional valves (and modular manifold system - NG16 and NG6) for direction, flow and pressure, give high performance, comprising two stage pilot operated solenoids with electronic spool position feedback, and integrated control electronics.

Performance is characterised by high resolution flow control and repeatability giving precise and reproducible control of actuator speed in rapid/slow modes, together with smooth acceleration/deceleration.

The NG6 version included, for the squeeze cylinder function, a pressure driven intensifier which allowed 220 bar holding pressure during curing, without the requirement of a high pressure pump.

For control, monitoring and regulating, a mini pressure sensor (SCP) has been employed for rapid pressure dependent analogue signals, using a zero point measuring cell with long term stability eliminating the need for calibration.

The compact unit is robust and the electronics are resistant to the effects of electromagnetic interference, and are protected from vibration and moisture.

The standard G1/4 BSPP thread is made of corrosion resistant stainless steel.

In addition, the power units, made to the customer's specification, meet all international standards, have low noise and filtration to guarantee a long life; the hydraulic piston pumps PV+ have low noise pressure, SensoControl, while the soft-seal (EO-2 Chrome Free) leak-free hoses and no-skive fittings have a three year leakage free guarantee.

Delivery of the first presses took place in the last quarter of 2005, with further deliveries through 2006, and 2007 when the programme will be complete.

A key member of the Parker team is Gunther Eberhardt, Account Manager, who says 'With Parker Hannifin being a global player, we are in prime position to handle sales/service around the world.' He continues, 'We have met all customer objectives, and in some instances have manufactured special versions of components specifically for this project.' 'This project has been proof of Parker's commitment to listening and working closely, not only with the machine builder, but also with the end user and considering the unique requirements of their particular industry - true teamwork.' Another key team member , Dominique Marceau, Key Account Manager dedicated to Michelin, echoes these sentiments, 'Parker has worked with Michelin for more than 30 years, is a highly valued supplier partner.

Michelin needed worldwide duplicable equipment to meets its demanding technical specifications, and our wide range, knowledge and worldwide implantation enabled us to meet their expectations completely'.

He continues, 'This Michelin Olsztyn Poland project has been realised thanks to a team: Parker Poland, Parker Germany and Parker France have been fully involved and worked together to achieve a common goal for our customer and we are very proud.

Modular air preparation increases reliability

2007-03-27T04:25:00.003-07:00

Parker Hannifin, the world's largest manufacturer of motion and control technologies, has supplied its Moduflex air preparation system to Hi-Force, the international supplier of high performance hydraulic tools, for use in its air driven pump units that complement its hydraulic torque wrenches. Parker's modular filtration system combines high performance with compact design and ease of installation. Hi-Force has been a leading manufacturer and distributor of high pressure hydraulic tools for over 20 years.

The company's extensive product range includes bolting tools and hydraulic torque wrenches specifically designed for accurately tightening and loosening threaded fasteners.

The wrenches require the use of hydraulic pump units, available from Hi-Force as electric and air driven versions.

As the products are used widely in the oil and gas, refinery and petrochemical industries, air driven tools are often preferred over electric.

Kevin Brown, Managing Director of Hi-Force, explained, 'In many cases hydraulic torque wrenches are required to operate continuously, sometimes 24 hours a day, especially during plant maintenance shutdowns, making reliability of performance absolutely essential.

The reliability of air driven hydraulic tools is entirely dependent on a regular supply of clean, lubricated compressed air, making it necessary to include an integrated air line filter, regulator, lubricator and pressure gauge alongside the pump motor.

Conventionally, these elements are bulky, poor quality, difficult to repair and replace, and require additional bowls.' To resolve these problems, the engineering, purchasing, sales and operations team leaders at the Hi-Force head office in Daventry were tasked with finding a more efficient and less problematic solution.

Parker was invited to submit samples of its filter, regulator, and lubricator units to Hi-Force for test and assessment.

Kevin Brown continued, 'The Parker Moduflex system was chosen for a number of unique benefits that it could offer over competing products.

The unit's compact dimensions and modular construction greatly simplifies pipework connection systems, with cast aluminium protection for both filter and lubricator bowls making the product extremely robust.

An integral shut off valve for the air motor was also available which previously had to be sourced and fitted separately.

While price was important, quality of the filters was the key requirement in order to maintain the strength of our global brand and to ensure that there would be no negative impact on sales.' The Moduflex modular system enables combinations of air preparation units to be built in a fraction of the time taken by more traditional systems, thanks to unique 'Cliplok' technology.

Combinations may be assembled quickly and easily, with the individual units combining face to face with no intermediate block and no increase in overall dimension.

Units can be fitted together without the use of pipe connectors, saving space while providing constant mounting centres.

The Cliploks slide into the units from the front and rear and can be locked into place, while Cliploks with integral wall brackets are also available for wall mounting.

Rotary transfer machines large volumes or batches

2007-03-23T00:49:00.003-07:00

A flexible changeover, rotary transfer machine enables higher levels of accuracy to be met and combines production sequences into a 'single-hit' cycle for large volume or batcgh production.

Developed to meet the future demands of automotive, medical, high pressure systems, and mechanical and electronic sectors of industry, the Mikron NRG-50 rotary transfer machine from Mikron Machining Technology Agno, Switzerland enables higher levels of accuracy to be met with the combination of a multitude of production sequences into a 'single-hit' cycle. Unlike traditional transfer machine technology, the Mikron NRG-50 is equally at home working on continuous production, as well as medium batches of family type components due to its highly flexible changeover capability and modular construction. A pre-requisite of the 12-station rotary transfer machine design was the establishment of high orders of mechanical accuracy, performance and flexibility achieved from the up to 140 CNC axes and 30 NC controlled machining heads able to provide up to five axes of movement.

It is capable of four-axis interpolation for milling cycles and is able to carry up to 96 tools with automatic tool changing if required.

Due to the construction and incorporation of thermal stabilisation techniques the Mikron NRG-50 has an accuracy capability of +/-4 micron and a deviation tolerance of +/-1.5 micron at a measuring diameter on the rotary table of 1400mm.

Up to three NC heads can be operated simultaneously at each machining station and the machine is able to turn by rotating the workholding collets at up to 6,000 rev/min.

It is also able to deep-hole drill, mill, thread cut, deburr and even carry out measurement, subassembly and testing sequences under its 'one-hit' production strategy, while meeting high levels of process security.

The machine will accept cubic parts with an edge length of 50mm or be fed from bar up to 35mm diameter with a part length of 70mm.

Control is through Bosch Indramotion MTX with an option of Fanuc 30i.

Software includes 3D simulation and CAM technology with unlimited program size.

Rotary transfer machine has more tools

2007-03-23T00:48:00.001-07:00

A machining spindle unit that can change up to four tools automatically within a production cycle has expanded the number of tools carried on a 12 station rotary transfer machine.

By developing a machining spindle unit with the flexibility to change up to four tools automatically within a production cycle, Mikron Machining Technology of Agno, Switzerland, has expanded the number of tools carried on its latest 12 station Mikron NRG-50, claimed to be one of the most advanced rotary transfer machines in the world. As a result the capability of the machine, which can perform both high volume and medium batch production involving up to five-axis simultaneous machining, deep hole drilling, milling, turning and even assembly cycles. It has up to 30 tools available as standard that can be applied to produce features on all six faces of a component in a single cycle.

With the ability to toolchange, the new unit head can now carry sister tooling to extend uninterrupted production, additional tools to produce complex features of a component or provide a quick-changeover solution, for instance to support family of parts production.

The innovative development by Mikron Machining Technology's engineers enables up to four tools to be carried around the spindle of the unit head.

The spindle has through tool coolant supply at up to 80 bar and an integrated air blast to clear the HSK 40-F taper shank of swarf or debris during the tool change.

Rapid tapping can also be programmed from the CNC control of the machine.

The stroke of the unit head is 70mm, the maximum spindle speed 10,500 rev/min and spindle torque is 0.9Nm.

The unit can be mounted in any position around the rotary table of the machine in the vertical plane, above or below the table, or horizontally.

And such is the power of the CNC control that up to 22 automatic toolchange units - each holding four tools, can be accommodated on the 12 stations of the machine.

In comparison with other indexing toolhead designs that usually utilise a 'revolver' style unit the Mikron system provides high stability due to a greater length of bearing support and therefore tool life and accuracy is improved and machining consistency more apparent.

To perform the toolchange which is a simple operation under CNC control taking just 2.5s chip to chip, the spindle stops and the unit head withdraws.

Using a hydraulic release, the magazine unit indexes 90 deg and the unit feeds forward to simply pick up on the taper of the new tool ready for production to continue.

Flexible machining system is user-friendly

2007-03-23T00:47:00.002-07:00

A simple, user-friendly machining cell has five machining modules mounted on the same frame, which combines the high productivity of parts within a 300mm3 cube with excellent flexibility.

The Vertiflex 300 machine is a simple and user friendly Flexible Machining Cell, suitable for the production of medium volume parts which can fit into a 300mm cube with minimum set-up times and reduced cost per piece. The machine is the result of the combination of more machining modules, horizontal (up to five) and vertical (up to three), mounted on a single frame; parts with five and more faces and of any shape or material are machined completely in one chucking to assure high quality finished products. Vertiflex is a reliable machine, manufactured in more than 100 pieces, installed all over the word.

Vertiflex 300 modular design allows for the investment flexibility; it offers the users the possibility to start with a basic configuration of three machining modules and expand at a later time with production growth.

Vertiflex 300's major features are as follows.

* Machining modules equipped with 7,5kW electro-spindles running at 6.000 rev/min, with linear roller guides on X and Y axes to grant high rapid speed, with optimum rigidity and precision.

* CNC rotary table for maximum reliability and minimum indexing time.

Independent CNC satellite worktables, available with indexing of 360 or 360,000 positions.

* automatic tool change with CNC operated six-spindle turret head with 1s chip-to-chip time.

* Hermetically enclosed work-area that allows for use of a large quantity of coolant, reduces noise level, avoids pollution of outside environment.

* Compact construction minimizing floor space requirement, without special foundations.

* Ergonomic loading/unloading station with automatic door.

Flexible production cell has 5-axis machining

2007-03-23T00:47:00.001-07:00

A flexible production cell with two independent single-spindle/twin-spindle machining centers and a four-position pallet changer, has been up-graded with a 5-axis version with faster tool change.

MC4 is a flexible production Cell with two independent single-spindle/twin-spindle machining centers and a four-position pallet changer, now up-graded with a 5-axis version. The machine can operate with two independent working stations, each one with five interpolating axes, with a chip-to-chip time lower than 1s. While one spindle is cutting, the other one changes the tool in concealed time and moves into position for the next operation.

Five-sided machinings can be therefore done in one chucking and simultaneously performed in the two working stations, without loosing the possibility to use the machine as twin-spindle (when A-axis is positioned at = 0 deg).

Overall machine design has taken operator ergonomic into consideration: in fact, it offers wide visibility and easy access to the machining area, as well as to the operator 's workstation.

The coolant and chips fall freely into the chip conveyor, thus avoiding overheating the table and the entire supporting structure, that would consequently affect machine performance in terms of accuracy.

* Machine frame - Riello Sistemi designed and engineered a monolithic frame with reticulated ribs to contain the machine weight and at the same time maximize static rigidity.

Positioning on few location points, no need for foundations and minimum floor space requirement allow for the machine to be transported fully assembled, quickly installed and easily moved in the workshop.

* Rotary tables - the two pallet-holder rotary tables are built with two rotating axes, perpendicular one each other (A- and B-axis) with a continuous CNC controlled motion.

The 'direct drive' motor assures excellent dynamics and high accuracy, thanks to the total absence of backlash and to the high resolution direct read-out of the position.

The pallets are positioned and clamped on four tapers, so assuring great stability and rigidity during machining operations.

* pallet changer - the four position high speed pallet changer allows for automated loading/unloading operations.

It can rotate of 180 deg or 90 deg so to run the two stations in parallel or in sequence.

* tool changer - the electro-mechanically driven tool changer grants high reliability combined with minimum changeover time; during the tool change, spindle and tool tapers are automatically cleaned.

* Guarding - overall guarding has doors allowing easy access, no telescopic covers, totally sealed and simple guards designed to preserve throughout time sliding guide-ways, motors, transmission elements and at the same time permitting easy access for maintenance.

Machining system support restructured

2007-03-23T00:46:00.000-07:00

Mikron Machining Technology has restructured its international customer support operations around its new Global Service Solution operation which has four discrete levels: Business Support, Product Support, Xchange Service and a Spare Parts Service. Customers are able to select service options from each level and create individual specific service solutions to achieve optimised productivity throughout the entire lifecycle of any Mikron machining system installation. The machining solutions based company, headquartered in Agno near Lake Lugano in Switzerland, has some 6,000 machines installed around the world and employs 65 people in its international customer support operations and service centres.

These provide a 24h global service line for problem notification.

The Business Support operation has been developed to help optimise the use of a Mikron system investment and provides a specialised consultancy service for re-tooling of rotary transfer and the highly flexible Multistep XS linear transfer machines.

Rotary transfer machines upgraded

2007-03-23T00:44:00.001-07:00

Manufacturer of rotary transfer machining systems has set up a department to source used Mikron rotary transfer machines for upgrading and re-sale.

A re-engineering technology department, Mikron Respeed Systems, has been set up by Mikron Machining Technology in Agno, Switzerland that is able to source a used Mikron rotary transfer machine from the 7,000 or so installations worldwide and supply a range of services and upgrades in technology according to customer requirements and budget available. As a result, an 'as new' Mikron rotary transfer machine can be purchased with application and project engineering support as a turnkey solution for a price around 50% of a new machine cost with a one year warranty and full support from the original manufacturer. Said Carmine Ruotolo, manager of Mikron Respeed Systems: 'We can offer an important advantage against second-hand dealers because of our historic files of previous machine installations around the world.

Also, our in-house team has the expertise and detailed knowledge of machine tool building and application engineering relative to special purpose technology.' The new department is complementary to the new machine business of Mikron Machining Technology and offers a range of options.

These include: to source and supply a machine from an existing Mikron user as it stands and provide whatever installation or modification, such as electric or safety upgrade the customer requires.

Machines can be re-tooled if required, or key elements partially or completely replaced, or a machine can be completely re-engineered, retooled and passed-off under customer acceptance procedures with a 12 month warranty exactly as a new machine.

Explained Ruotolo: 'We have often been requested to provide different levels of machine capability and technology at a reasonable investment, when customers need additional capacity, are setting up an operation in another facility or country or require backup for a key production process.

For customers that have extensive experience of our machines we can provide just the basic machine and equipment they need to enable them to complete a project themselves.' He then added an important factor is that a previously owned customer machine can be sourced and completely re-engineered and tooled using Mikron's skill and internal knowledge in four to six months - significantly shorter than a new machine build.

As a result, price structuring tends to be between 40 and 60% of a new machine purchase depending on the complexity of the project.

In re-tooling and re-engineering, Respeed Systems can add various degrees of automation, build in the flexibility of CNC axes to a previously mechanical driven machine frame and provide the full resource of Mikron Machining Technology departments for support when required.

Added Ruotolo: 'Important in all Mikron machine development is the original design criteria, modularity, construction and the accuracy that is built into the table, the indexing mechanism and the ability to use standard machine elements to quickly and simply re-tool.' He and his team of eight people and two apprentices understand the machines they are working on.

Ruotolo started in Mikron's service department at Agno as an apprentice in 1968 and progressed to become a service engineer and later technical consultant.

When Mikron Service was established in 1992 he was put in charge of the Multifactor rotary transfer machine product range and in 2004 charged with developing and structuring the Respeed Systems project.

Consequently, he has lived and breathed special purpose rotary transfer machines for almost 40 years.

To secure order entry and continuous work flow, a minimum stock of 15 machines have been sourced.

These have all been stripped down, the castings checked and any refurbish work carried out.

Tables, unit heads, electrics and electronics, coolant and hydraulic systems have been inspected and upgraded when needed, with new bearings, bushes, seals, and relays fitted.

He said: 'These machines are not cannibalised, they are used as a source of sound raw materials to which we can inspect and bring to 'as new' standard.' With up to eight machines now being re-engineered in the current factory area, one particular project involving a Mikron Multifactor 12-station rotary transfer machine is part of a two machine project for China.

The re-engineered Multifactor has a new autoloading system to produce qualifying operations on a compressor component and will work in conjunction with a new 15-station Mikron Multifactor machine being built to machine the remaining four faces of the component in a single cycle.

Machine tool maintenance scheme optimised

2007-03-23T00:43:00.000-07:00

Swiss machining systems builder has introduced an optimised maintenance scheme against a fixed price, checklist based contract that includes labour, spare and wear parts, and travelling.

Mikron Machining Technology of Agno, Switzerland has created a cost-effective method for European customers to forward plan servicing and ensure their installed Mikron machines are maintained in prime production condition. The Optimised Maintenance Scheme is not age related to the machine and has been devised to be proactive and driven by Mikron Machining Technology against a fixed price, checklist based contract that includes labour, spare and wear parts, and travelling. According to Axel Warth, global service solutions marketing and sales: 'Most Mikron rotary and inline transfer machines tend to be key production units, due to their high output capability and flexibility to combine several operations into a single automatic cycle.

This means preventative maintenance is of major importance to avoid unscheduled production stoppages due to breakdown.

However, because these machines are so important, production departments are always reluctant to release machines for service, especially by internal maintenance crews.

With our specialist knowledge we are able to independently drive the maintenance programme, minimise downtime and provide a cost-effective solution.' The Mikron scheme is priced and structured against the number of shifts the machines are run, the machine type, material and process requirements.

The service is structured to cover mechanical, electrical and electronics which includes the CNC units as well as safety, alignment checks and customer reporting.

This enables the Mikron service team to recognise and eliminate, in conjunction with the customer, any weakness, defect or problem at an early stage that prevents further deterioration leading to more serious damage, production delay and a higher cost to repair.

The scheme would be tailored to suit each machine and application with invoicing for the maintenance scheme following the first service visit.

Machining systems builder has 3D measuring

2007-03-23T00:42:00.000-07:00

Machining systems company may be the only one able to combine into a single measuring cycle touch-trigger probing with laser scanning and non-contact video measurement.

With the installation of the latest OGP SmartScope 650 Vantage 3D measuring centre with a full five-axis positioning capability, Mikron Machining Technology is able to combine into a single measuring cycle touch-trigger probing with Renishaw SP-25, laser scanning and non-contact video measurement. Mikron Machining Technology is believed to be the only company with such a modern laboratory providing a wide range of measuring equipment at the disposal of customers. Working closely with the Mikron service department it also provides qualified support when process checks are required by customers on their production machines.

In addition to the OGP SmartScope 650, equipment available in the laboratory includes three Mitutoyo CNC driven co-ordinate measuring machines, a SmartScope ZIP non-contact 3D measuring machine, Formtester surface measurement, a Profiletracer and Formtracer machines.

Following the latest installation, fully integrated measurement processes can now be incorporated using five-axis positioning of customer components in order to automatically carry out precise process capability evaluation of sample and machining trial components at the Agno, Switzerland machine tool build facility.

Explained Alan Franzoni, responsible for the measurement and quality laboratory at Agno, Switzerland: 'The quality laboratory is a key part of the whole machine tool operation.

We can check and verify in a single automated cycle, independent of the machine tool, all size and geometrical relationships of widely varying component features that tend to be combined into the typical parts that customers have purchased our machines to produce.' The SmartScope 650 measuring machine, with linear drives and a 500mm by 660mm by 300mm working envelope, has a resolution of 0.1 microns and is able to magnify, display and record elements of a component being inspected at up to 400 times magnification.

The ability of the SmartScope 650 to independently replicate five-axis positioning, remote from the machine tool, is very important as many components produced on the Mikron range of machines involve compound angle holes or features.

These are machined to meet key target areas for start and breakthrough positions to provide oil and fuel feeds, such as in fuel injection, hydraulic and pneumatic valves and pumps.

Indeed, in line with the type of components being produced, extremely close tolerances tend to be applied to size, geometry and surface finish specifications produced by the Mikron range of rotary and in-line transfer machine tools.

So, included in the measuring machine installation is a specialist 0.1mm diameter Apollo probe and Renishaw probe autochange that is able to accommodate automatic measuring cycles to check batches of machined samples.

One important advantage for Mikron's inspection team is that with the programmable integration of video, laser scanning and contact measurement, precise data of chamfers, forms and radii plus monitoring and visual display of edge definition and burrs on the intersection of internal hole breakthroughs, can be made.

In addition, full and detailed process control analysis of collated measurement data can be performed in 'real-time' using the Mitutoyo StatPAK statistical process control software and QC-CALC software that is fully networked with other CNC controlled measuring equipment in the laboratory.

The capability of Mikron machines spans small batchwork to high volume production.

The highly flexible Mikron Multistep and latest development, the 140-axis Mikron NRG-50 rotary transfer machine, cover small to medium batch production while MultifactorTM and MultistarTM, the fastest transfer machine in the world, is capable of producing up to 480 parts/min.

With such demanding component complexity and production requirements, the measurement and quality laboratory is very closely involved with the original application engineering and machine quotation team at the initial project appraisal.

As a result, parameters can be set for measurement and process control to ensure the production solution will fully accommodate the often complex design requirements of the customer.

When the project turns into an order, the department creates an initial measurement protocol for the various features of the component.

This is agreed with the customer and as key structural and moving elements of the machine tool are manufactured such as the rotary table, Hirth indexing ring, fixture locations and datums, these are inspected by the quality laboratory and appropriate data recorded in the project file.

Once the machine is built, alignment checks are performed on the machine and initial 'first chip' parts are measured to establish that the precise geometric, size and surface finish achieved matches the customer specification and order requirements.

When 'first chip' processed parts are accepted by the project team, the next stage is to take a minimum number of five parts from each fixture of the machine to ensure the process is repeatable.

Said Franzoni: 'Bearing in mind a Mikron transfer machine can have up to 24 stations it is here the Mikron measurement and quality laboratory will play an important part.

Only when the machining criteria is established is a four hour production run initiated during which time further parts per fixture of the machine are collected and catalogued every five minutes to determine internal acceptance of the process.

This is performed prior to the customer being called for its own acceptance trials when the Mikron laboratory is put at the service of the customer.'

Wheel loader optimises performance with hydraulics

2007-03-15T00:36:00.000-07:00

Parker Hannifin has supplied a complete set of hydraulic products and components to Ljungby Maskin

By offering an integrated solution from a single supplier, Parker is helping the Swedish wheel loader manufacturer to obtain optimum performance from its machines while reducing costs, and proving one point of contact for around the clock local support. Ljungby Maskin manufactures approximately 130 machines a year, with its high performance wheel loaders ranging from nine to 30 tonnes in weight, and capable of moving earth, logs, building debris, and a diverse variety of other heavy materials. When the company wanted to redesign this range, it was decided that it would attempt to identify a single supplier capable of providing a total hydraulic solution including gear pumps, piston pumps, valves and accumulators.

This was due to the company's preference for one point of contact for support, as opposed to several suppliers which would make access to advice and technical knowledge overly complex and increase the costs associated with ordering and replacing components and equipment.

When Ljungy Maskin explained the requirement to a small number of carefully selected potential suppliers, Parker formed a project group involving its Swedish sales and technical service, the Boras hydraulic application centre, and the European mobile hydraulic team to focus specifically on Ljungby Maskin's needs.

Six Parker experts visited the company and after listening to the specifics of what was required, offered them a solution which involved complete integration, making support issues as simple as possible and also keeping costs at a minimum.

Prototype systems were designed, built and implemented for the Swedish manufacturer before a solution was chosen based around Parker's dedicated set of hydraulic products and components, ideally suited to wheel loading equipment.

The product set to be used with the machines included the high performance, self priming, P3 piston pump and M-series directional control valve, together offering consistent levels of high power to the machines' load arms, steering and brakes offering the wheel loaders the ideal combination of power and speed.

A system for good control, leak proof operation in a harsh working environment in which the machines would be operating.

A variety of ergonomic controls such linear levers and multi function joystick were also chosen for easy operation and manoeuvring.

This extensive product range gave Ljungby Maskin the opportunity to rethink the hydraulic architecture of its machines, improving the performance and efficiency of products such as the L30 wheel loader even further.

Ljungby Maskin Technician, Bengt Johansson, is certain that they made the right choice, 'As well as offering us the most robust and high performance products available, Parker's worldwide support network offered added benefits'.

'It is so much easier to have one company to work with, there is only one person to call when you need support, and with Parker's support centre just 150km away, under two hours drive, the infrastructure was there to provide us with the help we needed to continue to develop the high performance machines that we're known for, and lower costs in the process'.

Hydraulic systems help bring smack back to life

2007-03-15T00:23:00.009-07:00

Hydraulic motors, modular load sensing hydraulic valves and hydraulic proportional remote controls feature in a unique marine restoration project.

Parker Hannifin has supplied its hydraulic motors, modular load sensing hydraulic valves and hydraulic proportional remote controls to a unique marine restoration project commissioned by the Pioneer Sailing Trust. The restored vessel's twin propeller design, made possible by hydraulic transmission system specialist Anglian Diesels, using Parker Hannifin's products, is enabling a combination of outstanding manoeuvrability and impressive cruising speeds. The Pioneer Sailing Trust was established in 1999 by Rupert Marks, Brain Kennell and Shaun White, with the purpose of restoring back to sailing condition the last remaining first class Essex skillinger smack, named Pioneer.

The 21m-long smack, originally built in 1864, was an abandoned wreck lying in the mud at West Mersea when the trust took on the project; after 4 years of careful restoration, the boat was successfully relaunched at Brightlingsea.

Rupert Marks, one of the founders of the trust, said of the project: 'It was important to us that Pioneer's restoration be carried out with the greatest respect to the original design, using the highest quality materials and suppliers, while making it a modern vessel in terms of performance and functionality'.

Unlike its original incarnation, which was powered by wind, the restored Pioneer is powered by a single diesel engine with a hydraulic transmission system, supplied by marine specialists ARS Anglian Diesels, driving the vessel's twin propellers.

The system incorporates two pump powered Parker F12-80 hydraulic motors fitted to the top of sonic legs, creating the effect of a hydraulic outboard motor system.

The F12 motors are extremely lightweight and compact with just a 40-degree angle between shaft and cylinder barrel.

Despite this lightweight design, their heavy duty roller bearings permit substantial external shaft loads and combine with the motors' limited number of parts to result in an extremely robust design with long service life and proven reliability.

Powering the Parker motors can require less fuel than conventional products because of their high overall efficiency and the use of only one engine to drive two propellers.

The fixed displacement F12-60 pump is used in conjunction with a small 22 litre oil reservoir and Parker's BLA6 250 boost unit.

The BLA6 boost unit is a non mechanical device which enables the engine to use its full power without allowing the pump to 'cavitate' and it creates a 'semi-closed-loop system' which allows the use of a much smaller oil reservoir.

Pioneer's two hydraulic motors are controlled with Parker's PCL402 twin function friction braked control levers.

These are used in conjunction with a Parker L90LS modular hydraulic valve to control the power efficiently and proportionally from the pump to the two motors.

The valve only allows a maximum of 90 litres of oil to go to any one motor at any time, this irrespective of engine speed, which prevents the 'overspeed' of any one propeller.

The twin propeller system enables the power to be directed to one single propeller or both, in either direction of rotation, for easy manoeuvrability, allowing both propellers to be used for cruising, with the load sensing valve, ensuring that the correct amount of oil is pumped to each propeller, the system has an overall reduction ratio of 2.66:1.

The small dimensions of the PCL402 remote control unit made installing it into Pioneer easy, with its robust, simple design offering excellent reliability and performance.

The user friendly equipment enables smooth and easy control of the vessel, and greatly assist in its new purpose, as a training centre.

The smacks were originally working boats, dredging oysters or scallops from the coasts of the UK and northern Europe, but Pioneer has a very different purpose in its restored state, being used to train people in sailing, teamwork and leadership, able to accommodate three crew and 12 trainees.

Marks commented: 'The trust is making the boat available to those people who might best benefit, but who may not normally have access to such opportunities'.

'We are working with life development trusts, training agencies, councils, social services, schools and other organisations committed to social welfare'.

Hydraulic pump suits noise-sensitive applications

2007-03-15T00:23:00.008-07:00

Second-generation radial piston pump provides OEMs and end users with a number of important benefits.

Described as the ultimate in drive technology for stationary hydraulics applications, the new RKP-II second-generation radial piston pump from Moog provides OEMs and end users with a number of important benefits. Of particular interest are those related to noise, durability, efficiency and service life. An increased number of pistons, modified suction porting and redesigned stroke ring enhances fluid delivery, decreases flow pulsation, increases life and significantly lowers noise levels.

Initially available in 63, 80 and 100cm3 per revolution variants, its radial design offers many advantages compared with axial piston pumps such as low output pressure pulsation.

In most model sizes, an increase in the number of pistons from seven to nine reduces the piston diameter lowering the affect of dynamic transverse forces on the housing.

This means the RKP-II runs virtually stress free and is less subject to piston wear and detaching slipper pads.

Volume, flow and pressure pulsations on the high-pressure side are also noticeably lower.

The RKP-II with its completely re-engineered power train is ideally suited for integration into a wide variety of machines and installations.

According to Moog, these include those involved with tool production, plastic and metal forming, injection and pressure casting, rubber processing, test-bench construction and mining.

It is the pump's design that makes it the number one choice for these noise-sensitive stationary hydraulics applications the noise intensity for sizes 63 and 80 is less than 70dB at any working point allowing the RKP-II to support the implementation of the EU noise guideline 2003/10/EC.

It is designed to be highly resistant to wear and, as a result, is more tolerant of negative suction pressure.

This is due to all the parts associated with fluid flow dynamics being hardened eliminating pitting caused by cavitation.

Approved for a variety of operating fluids, the RKP-II has a number of control options to guarantee optimum flexibility no matter what the application.

It has significantly reduced maintenance requirements and its virtually unlimited storage life addresses many issues related to stocking spares especially important for manufacturing environments that are operating using modern lean principals.

The introduction of a larger suction port (SAE 2in - 207bar) together with an improved flow path in the housing and new porting in the journal means the RKP-II can offer extremely robust suction behaviour with optimum intake, less pressure loss along the suction path, lower flow noise and reduced risk of cavitation.

Teamwork is efficient solution for tyre presses

2007-03-15T00:23:00.007-07:00

With international demand for vehicle tyres heading towards Eur 1 billion per annum, competition is tough, and companies such as Michelin are constantly striving to improve productivity and efficiency and respond to the expectations of vehicle manufacturers and consumers in terms of safety, respect for the environment, price, comfort, and ergonomics. When new investment was planned for its plant in Olsztyn, Poland, Michelin wanted to ensure that all materials, machinery (and components therein) would contribute to these objectives, which meant reliability, quality, low maintenance and cost-effective running. As part of this programme machine builder Harburg Freudenberg Maschinenbau was chosen to provide tyre curing presses on a multi year period, and in turn, Parker Hannifin products were specified as a single source of hydraulic and pneumatic components because of the company's expertise and proven record of accomplishment within previous projects with both Michelin and Harburg Freudenberg.

The curing process is where tyres get their final shape and tread pattern.

Hot moulds shape and vulcanise the tyre.

The moulds are engraved with the tread pattern, the sidewall markings of the manufacturer, and others required by law.

Tyres are cured at about 150C for 12-25min, depending on their size, and are then 'popped' from their moulds, taken to final finish and inspection.

The demanding specification for the curing presses and the hydraulic and pneumatic components therein was drawn up by Michelin, and was exact, calling for quick startup, precise positioning, cost savings, high efficiency, low maintenance, and, with future projects in mind, worldwide service support.

Working alongside other Parker European divisions (France and Germany) Parker Poland co-ordinated all specifications, drawing up the project plan and liaising with all parties concerned, proving the benefits of local support, service (and availability of parts), and has been on-call during the development, production and commissioning stages, even providing tailor-made components, via Parker manufacturing plants in Germany.

Products include hydraulic control units, power units, hydraulic cylinders, sensor, and valves, together with pneumatic connectors, hoses and couplings.

The column type presses incorporated customised hydraulic roundline cylinders from Parker.

The rod and piston assemblies being fatigue free at full rated pressure, and seals housed in corrosion-resistant steel glands which provide retention of pressurised fluid while preventing the ingress of contaminants.

The heavy duty polymer bearing rings resist side loadings, and the wide separation of these rings reduces bearing stresses, extending the service life of the bearing itself.

Together with a high surface finish to the high density wall steel tubing to minimise internal friction and prolong seal life; cushions at the head and cap provide controlled deceleration reducing noise and shock loading extending machine life; these cylinders will give exceptional service in any rugged, tough, high demanding environment.

Maintenance is simple and easy with the rod bearing and rod seal being replaceable without completely dismantling the cylinder - and in the event of an emergency the flanges are spaced away from the head and cap to allow the bolts to be sawn through quickly.

Hydraulic proportional valves (and modular manifold system - NG16 and NG6) for direction, flow and pressure, give high performance, comprising two stage pilot operated solenoids with electronic spool position feedback, and integrated control electronics.

Performance is characterised by high resolution flow control and repeatability giving precise and reproducible control of actuator speed in rapid/slow modes, together with smooth acceleration/deceleration.

The NG6 version included, for the squeeze cylinder function, a pressure driven intensifier which allowed 220bar holding pressure during curing, without the requirement of a high pressure pump.

For control, monitoring and regulating, a mini pressure sensor (SCP) has been employed for rapid pressure dependent analogue signals, using a zero point measuring cell with long term stability eliminating the need for calibration.

The compact unit is robust and the electronics are resistant to the effects of electromagnetic interference, and are protected from vibration and moisture.

The standard G1/4 BSPP thread is made of corrosion resistant stainless steel.

In addition, the power units, made to the customer's specification, meet all international standards, have low noise and filtration to guarantee a long life; the hydraulic piston pumps PV+ have low noise pressure, SensoControl, and the soft-seal (EO-2 Chrome Free) leak-free hoses and no-skive fittings have a three year leakage free guarantee.

Delivery of the first presses took place in the last quarter of 2005, with further deliveries through 2006, and 2007 when the programme will be complete.

A key member of the Parker team is Gunther Eberhardt, Account Manager, who says: 'With Parker Hannifin being a global player, we are in prime position to handle sales/service around the world'.

He continues: 'We have met all customer objectives, and in some instances have manufactured special versions of components specifically for this project'.

'This project has been proof of Parker's commitment to listening and working closely, not only with the machine builder, but also with the end user and considering the unique requirements of their particular industry - true teamwork'.

Another key team member, Dominique Marceau, Key Account Manager dedicated to Michelin, echoes these sentiments: 'Parker has worked with Michelin for more than 30 years, is a highly valued supplier partner'.

'Michelin needed worldwide duplicable equipment to meets its demanding technical specifications, and our wide range, knowledge and worldwide implantation enabled us to meet their expectations completely'.

He continues: 'This Michelin Olsztyn Poland project has been realised thanks to a team: Parker Poland, Parker Germany and Parker France have been fully involved and worked together to achieve a common goal for our customer and we are very proud'

Hydraulic high pressure tools gain Indian agency

2007-03-15T00:23:00.006-07:00

Project Sales Corp has been appointed agent for Schaaf in India. Founded in Erkelenz in 1977, Schaaf develops and manufactures products in the field of hydraulic high pressure tools and high pressure generators. First use of this technology goes back to developments undertaken in the 1950s, by Martin Schaaf, the founder of the company.

At that time, he developed hydraulic bolt tensioners to avoid the irregularities when tightening bolt connections at valve heads of piston pumps by hand.

Further developments were brought to market maturity and lead to various patents in the area of axial pre-tensioning.

In 1990, Ralf Koellges, his colleague and assistant for many years, took over the company.

Today, a team of highly qualified technicians is continuously broadening the range of the companys' activities by improving existing equipment and turning new developments into innovative products.

Schaaf engineers and manufactures: bolt tensioners, high pressure cylinders, hydraulic mounting and dismounting devices, special devices, hydraulic high pressure accessories, hydraulic high pressure pumps, control units (manual, pneumatic, electric), the A-Loc roll ring locking system, hydraulic nuts, composite rolls for bar and rod mills, test stands, test bolts, washers, hydraulic clamping frames and other tools and equipments.

Pneumatic cylinders add intelligence to smelting

2007-03-15T00:23:00.005-07:00

Parker is helping the Elkem Aluminium plant in Mosjoen, Norway to streamline processes and significantly increase efficiency through the use of its intelligent pneumatic crust breaking cylinders. As well as being able to withstand the extreme conditions within an aluminium smelter, the cylinders feature leading edge closed loop control, to improve the performance of the feeders and enable the plant's cell operators and maintenance crew to respond to problems quickly, reducing the number of anode effects (and thereby greenhouse emissions) and also increasing productivity. The successful smelting of aluminium relies both on a controlled supply of aluminium oxide, also known as alumina, in order for production to be optimised and for anode effects to be prevented, to minimise greenhouse emissions and potline disturbances.

Prior to implementing the Parker technology, the Elkem plant was operating conventional crust breaking cylinders with fixed dwell times, regularly attempting to break the crust which forms on top of the alumina and cryolite mixture in a smelting pot, as a part of the alumina feed operation.

The dwell time selected was a compromise between having sufficient time to achieve enough plunger force, and a short enough time to avoid electrolyte deposits sticking to the plunger.

There was no feedback on whether the crust was successfully broken, often resulting in alumina being poured on top of the crust and not entering the mixture, resulting in anode effects.

In response to these problems, manual checks were frequently required, with process staff having to lift heavy covers from the pots in order to monitor their condition.

With 1100 feeders at the plant, needing one or two inspections every shift, this required a significant amount of man hours.

These spot inspections were also relatively inefficient as there can be an anode effect just 15min after a feeder stops working.

Roald Hvidsten, Process Control Manager at the Elkem plant, explained: 'Previous to integrating the Parker cylinders, we were experiencing 0.4 to 0.5 anode effects per pot-day'.

'As well as the resulting impact on production, these anode effects were causing the release of CF gases into the environment (CF4 and C2F6)'.

'They have a greenhouse equivalent of 6500-9500 times compared with CO2, and a lifetime in the atmosphere of 10,000 years'.

'We required a solution that could both solve our operational issues and reduce these emissions in line with government guidelines; Parker offered us the cylinder that is the key component in our closed-loop feeder control'.

He continued: 'Parker's experience as the leading supplier of pneumatics to the aluminium industry, made it clear that they were best suited to supplying us with the crust breakers'.

'Its products' proven ability to withstand the high temperatures, strong magnetic fields, electrical arcing, and abrasive environments typical of aluminium smelters, reassured us that we would end up with a robust solution that would last'.

'An important consideration in the project was to not introduce more critical components'.

'The 'intelligent' parts added to a standard cylinder would not be able to stop the feeding in case of a fault'.

In particular, Parker's intelligent crust breaking cylinders have been one of the key enablers for Elkem to reduce the rate of anode effects per pot from one every second day to approximately one every 10 days.

The chisel ended piston of each cylinder is lowered in order to break through the alumina crust and is given six seconds to do so successfully, as opposed to 2.4 seconds with the previous crust breaking solution.

The extended time allows a full air- pressure build-up and maximum chisel force when there is hard crust.

This keeps the feedhole open longer; otherwise, when the feed hole is open, the chisel retracts immediately before it gets overheated preventing the electrolyte sticking to it.

The whole feeder cycle is monitored by checking the two end switches for status and timing.

Any malfunction is alarmed, either to the process operators or to the mechanical maintenance group, depending on the type of failure.

Process alarms (such as stuck chisel, hard crust) are sent to the pot operators via PDAs in dedicated small crust-breaking vehicles, allowing them to go straight to the pot that is reporting a problem.

These alarms must be handled within 15-20min in order to avoid anode effects.

In case the feeder control identifies a technical fault (such as a stuck end switch), the control switches to a fall-back mode, operating as a 'dumb' feeder, while alarms are given to the maintenance group.

These problems can wait until next workday, as the feeder continues to work (although with reduced functionality).

Product development for the cylinders was carried out in an environment matched to the harsh conditions found inside the plant's reduction cells, with high temperatures, heavy abrasive dust, and strong magnetic fields present, resulting in cylinders that are able to operate continuously at 150C or intermittently at 200C, with no need for additional lubrication.

They are effectively sealed against dust (and in this case alumina) and offer a service life of 20 years, with maintenance-free operation for five years, delivering repeatability, accuracy, and rugged dependability for high volume production requirements.

Roald Hvidsten is clear about the benefits that the Parker cylinders are offering the Elkem plant: 'The intelligent crust breaking cylinders have greatly increased efficiency levels at the plant, significantly cutting the number of anode effects that occur'.

'The new feeders give a better mechanical performance, and also replace the earlier 3300 routine inspections per day with around 80 actions to feeder alarms on our 404 cells'.

'Through the automated closed loop control that they offer, we are able to utilise our resources much more effectively, and increase productivity as part of a complete solution'.

Hydraulic dampers produce consistent force

2007-03-15T00:23:00.004-07:00

Hydraulic dampers include an innovative balance chamber to produce a constant travel speed, resulting in a smoother and consistent damping force.

Catalogue simplifies hydraulic cylinder ordering

2007-03-15T00:23:00.001-07:00

Parker Hannifin has released a new catalogue detailing the features and specifications of its 2H series hydraulic cylinders. The heavy-duty cylinders incorporate a number of features such as tie rod construction enabling them to offer outstandingly long and efficient service life under high working pressures. Parker hydraulic cylinders offer a compact and cost-effective method of moving, positioning or clamping tools or work-pieces in a variety of industrial applications, ranging from automation and machine tool systems, to presses, injection moulding and die casting machines.

The heavy-duty 2H series incorporates a number of innovative features, designed to improve overall performance and reliability, while extending operating life.

The cylinders' piston rods are manufactured from precision ground, high tensile carbon alloy steel, hard chrome plated and polished, to eliminate the problems caused by impact damage, scratches and abrasions which result in shortened gland seal life.

Similarly, the steel cylinder body tube is surface finished to minimise internal friction and wear, prolonging the life of piston seals.

The cylinders feature pressure-energised body seals to ensure that leakage is prevented even under pressure shock conditions.

As well as lip seals manufactured from an enhanced polyurethane, with a life of up to five times that of traditional materials, the piston rods also feature a double lip wiper seal that prevents the ingress of dirt into the cylinder and as a result extends the life of gland and seals.

2H tie rod cylinders are available in a range of bore sizes and stroke lengths, and are able to withstand working pressures of up to 210 bar.

Optional features include end of stroke cushioning for controlled piston deceleration, bespoke rod and port sizes, stroke limiters for use where absolute precision in stroke length is required, and rod locking devices providing fail-safe operation.

The new 2H series catalogue is now available, detailing these features in depth and listing the properties (including dimensions, and mass and nominal force) of the entire product range.

Sections are included on cushioning, pressure limitations and ports, and seals and fluids, making the catalogue a useful reference guide, while a how to order section makes product selection refreshingly simple.

Hydraulic hoses fitted to Navy ship

2007-03-15T00:23:00.000-07:00

Rotec Hydraulics has recently completed a major contract to supply, configure and install hydraulic hoses as part of a refit programme for the Royal Navy's amphibious helicopter carrier, HMS Ocean. The latest DEF STD 47-2 Parker Defender hydraulic hoses and fittings were used throughout, providing a unique combination of flexibility, ease of installation and ability to function reliably under extreme operating conditions. With a maximum complement of 1275 and a displacement of 22,500 tonnes, HMS Ocean has been designed to provide amphibious assault capabilities anywhere in the world, with secondary roles including training, anti-submarine warfare and a base for anti-terrorist operations.

The ship is capable of carrying Sea King or Merlin medium support helicopters, Apaches, Gazelles or Lynx helicopters and landing craft, plus a wide range of support equipment for her complement of Royal Marines.

As part of a major refit undertaken recently at Devonport Dockyard, Rotec Hydraulics was commissioned to inspect and, where appropriate, replace many of the existing hydraulic hoses and fittings used throughout the vessel.

These are used extensively on boat davits, forward and aft aircraft lifts, stern and starboard quarter loading ramps and other hydraulically powered units.

Terry Light, Sales Director at Rotec Hydraulics, explains that, 'The key requirements for the new hoses and fittings were reliability and safety'.

'It is essential that the various on-board hydraulics systems function effectively even under the most arduous conditions'.

'For example, the hoses and fittings used on the boat davits are constantly exposed to extreme weather temperatures, strong sunlight and salt water yet have to withstand considerable hydraulic shock and mechanical stress'.

'Similarly, each aircraft lift imposes high dynamic and mechanical loads on the hydraulic systems quickly and smoothly from hangar to flight deck'.

The use of Parker's latest Defender Defstan hydraulic hoses, combined with Parker's stainless steel and passivated zinc fittings, enabled Rotec to produce hose assemblies that are quick and simple to fit yet provide an exceptional level of performance and reliability.

For example, the Defender hoses have a carefully designed three-layer construction, with an inner core manufactured from a seamless oil-resistant synthetic rubber, reinforced with one or more layers of braided or spiralled high tensile steel wire and covered with an outer layer of tough synthetic rubber.

Defender hoses can therefore be used at temperatures ranging from -40 to +100C, with working pressures of between 40 and 500 bar, and will withstand abrasion, weathering and ozone degradation.

In addition, the method of construction ensures low volumetric expansion for rapid, accurate hydraulic response and reduces both the weight of each hose and the bend radius, making hoses easier to install in confined areas.

Rotec and Parker worked closely with the Royal Navy technicians to ensure that the project was completed as quickly and efficiently as possible.

Terry Light adds that, 'Our engineering workshop and ParkerStore in Plymouth was used for all hose and fittings supply, plus assembly and testing, with our engineers completing the installation on-board while HMS Ocean was in Devonport Dockyard'.

What to do when hydraulic hose or couplings fail

2007-02-15T21:34:00.001-08:00

Choosing the right option for emergency replacement of hydraulic hoses and couplings is essential to minimise costly downtime in the case of leaks or system failure.

In this situation, plant engineers still have three options; use a local specialist, a mobile van service or install a DIY/self assembly facility. However, changes in working practices, developments in jointing technology and recent broadening of available equipment ranges have changed what might be the right choice both in terms of reliability and overall cost effectiveness.

One of the first things to consider is the size of a site and the average number of failures experienced in a month.

Many smaller manufacturers with relatively few failures (less than five per year) often rely on outside companies who specialise in hydraulic hose assembly as a quick and reasonably cost effective method.

However, this solution still relies on an in-house engineer physically taking the hose to a specialist and waiting for a new assembly to be produced, a process that can still take up valuable time even if the order is sent ahead of delivery.

It is worth noting that a plant operating 24hrs a day can incur extra costs when repairs have to be completed outside working hours.

For companies that have similar numbers of failures and have multi-site facilities or are in remote locations, the preferred solution is the mobile van service.

The mobile option is ideal for quarries and other processing industries as it is a speedy solution that does not rely on in-house engineers and supplies all the necessary stock and equipment.

Call out charges are substantial for the service however, and there is always a chance that the van is not immediately available, the correct components are not on board or the fitting requires more pressure than a mobile crimper can provide.

Larger companies with in-house tool shops have traditionally relied on their own engineers to complete the repair and therefore significantly reduce the downtime caused by hydraulic failure.

In the past, this option has been ignored by small to medium sized companies due to the high cost of crimping machines, stock carrying and training requirements.

However, companies are now realising that the amount of replenishable stock required to account for all eventualities, can in fact be relatively small and, the next generation of crimping machines include smaller and less costly models, making them a far more attractive proposition.

Despite large industrial suppliers providing both on and off site hydraulic repairs, many of these companies believe that self-assembly is the way forward and have responded by supplying a budget range of mobile manual crimping machines designed for maintenance operations and small production runs.

For as little as GBP 1200, companies can now purchase tailored self-assembly kits which consist of a manual crimper, a selection of couplings and up to six hose sizes that allows any employee to produce new hoses covering most applications.

By following the simple step by step instructions provided, staff can produce a factory-quality hose assembly in under five minutes, which is less time than it would take to order a new one from a third party supplier.

When compared to the cost of mobile suppliers, the complete set up can pay for itself in as little as five failures.

For medium volume production runs across the entire hose range, larger stationary crimpers are also available at more accessible prices, with models designed for hoses of a higher-pressure range and providing reliable operation in the toughest field applications.

In the past many companies have experienced failures after in-house repairs due to the fact that the range of hosing and couplings available were often not of a high enough quality.

In contrast, quick fit coupling designs are now available that avoid the need to remove the hose cover or lining (skiving) and are made from one cast piece of material rather than brazed construction, eliminating the common causes of failure.

The hose itself has also undergone price changes and offers an improved construction with the most recent designs providing higher resistance to external oil and grease and protection against abrasion, even where dirt is attracted to the lubricants.

To ensure that the correct stock is always at hand, accounts can be set up with the larger industrial suppliers such as Wyko who, thanks to their unique partnership with Gates can deliver their high quality replenishment hosing and couplings stock anywhere in the UK, 24 hours a day.

Wyko provide replenishment stock on a next day basis as standard, allowing companies to reduce inventory without the risk of extending downtime.

When combined with a policy of standardisation on the size of terminations and the use of inexpensive adapters across a site, this can greatly reduce stock levels and costs.

In addition to the crimping machines and components, a full range of workshop equipment to speed up the crimping operation is also available, including rotational tables for unwinding hose coils, storage cabinets, hose cutting and pressure testing machinery.

Hydraulic damper units are self-contained

2007-02-15T21:33:00.002-08:00

Self-contained hydraulic damper units provide a fully adjustable controlled feed rate when a load is applied to them. Automation control equipment manufacturer Ace Controls International is extending its range of hydraulic dampers with the addition of model HB-70. This new and now the largest hydraulic damper they offer, has a 70mm diameter and extends the resistance range from 10,000N to 50,000N.

Five models now complete the line-up the HB-15, 22, 28, 40 and 70.

Stroke lengths range from 25mm all the way up to 800mm.

All Ace hydraulic dampers are self-contained units.

They provide a fully adjustable controlled feed rate when a load is applied to them.

They can be specified to control the velocity for either the out stroke, in stroke or in both directions.

Typical applications include machine guards and lids, fire safety flaps and doors, damping oscillations of suspended loads, smoke and roof vents and much more.

Fire resistant hydraulic fluid has double life

2007-02-15T21:33:00.001-08:00

A fire resistant hydraulic fluid complies with the latest Group 1-Factory Mutual standard 6930 that becomes effective from July 1st 2003 and offers double the in-service life of comparable products.

Castrol has launched a new fire resistant hydraulic fluid to comply with the latest Group 1-Factory Mutual standard 6930 that becomes effective from July 1st 2003. The new fluid combines a best-in-class fire protection rating with more than double the in-service life of comparable products. Called Anvol SWX, the new Polyol Ester fluid offers significantly higher fire protection than traditional mineral hydraulic fluids and a 12% higher fire point than any other Group 1 fluid.

Tests also showed that Castrol Anvol SWX lasted two-and-a-half times longer than comparable fluids, significantly extending its operational life.

Commenting on the launch, Daryl Luke Castrol European Product Manager - lubricants says fluids such as Anvol SWX are essential for the safe, cost-effective operation of hydraulic systems in any plant where there is a risk of fire.

'In a steel mill, for example, a broken hydraulic hose could cause fluid to leak at pressures of up to 5,000psi, with potentially disastrous results if a traditional fluid came into contact with a naked flame or a hot or molten metal.' He says.

Castrol Anvol SWX also offers the potential for cost savings in areas of fire risk as Factory Mutual does not require expensive secondary fire-suppression equipment to be installed if a Group 0 or Group 1 fluid is used.

Other important benefits include a safer working environment for staff and, by minimising sludging and varnishing, a lower risk of damage to vital equipment such as valves and pumps, with a resultant reduction in production stoppages.

Improved corrosion protection, even in the worst water conditions, limits the threat to internal ferrous components in the hydraulic system and better wear protection properties for moving parts helps to reduce hydraulic pump maintenance and replacement costs.

Hydraulics keep Prado Museum on the level

At Spain's prestigious Prado Museum in Madrid, Enerpac Hydraulic Technology was consulted as specialists for the solution to control the ground movement

In the heart of this magnificent city earth is moved by excavators to construct the museum's extension. The new exhibition space is partly underground, stretching from the existing Prado buildings to the adjacent 16th century Jeronimo Church.

An Enerpac PLC-controlled synchronized hydraulic system monitors and adjusts any foundation movement between the church, the Prado Museum basement and surrounding buildings during construction.

The museum, built in 1819, wants to distinguish itself from two other museums in Madrid - the well known Thyssen-Bornemisza Collection and the Reina Sofia Museum of contemporary art exhibiting Pablo Picasso's famous Guernica.

The Prado Museum is renowned as being the largest art gallery in the world.

It also exhibits sculptures, drawings, coins and other works of arts, but it is undoubtedly its large collection of paintings which has given it fame worldwide.

It houses more than 8,600 paintings, of which they exhibit less than 2,000 because of lack of space available.

Many museums throughout the world have less artistic riches in their halls than the Prado Museum has in storage.

The Prado extension, a project of 42 million euro started in April 2003.

After opening, early 2004, the Prado extension will house a library, a workshop, an auditorium and temporary exhibitions.

It is expected that the yearly 1.8 million visitors will increase to 2.5 million.

In the design of the extension by the Spanish architect Jos‚ Rafael Moneo, much of the new space is underground on two levels.

A tunnel forms the connection between the existing and the new Prado buildings.

The 16th century Cloister of Jer¢nimo has been removed stone by stone and will be re-assembled in the new museum's extension.

Where the cloister stood, excavators dug a pit of 46 x 20 x 20 meters (lxwxh).

Such a large hole will make the foundations of the surrounding buildings and roads unstable.

A solution was required to support the walls of this pit with the ability of controlling any ground movement.

Enerpac Hydraulic Technology was consulted as specialists in integrated hydraulic systems and 700 bar high pressure hydraulics for the solution to control the ground movement.

The new extension underground has two floor levels.

During the construction period any foundation movement must be controlled using hydraulic jacks.

On each floor level 17 hydraulic jacks are positioned horizontally between the supporting walls and the concrete floors.

The concrete floors are not yet fixed into the surrounding basement walls but have a floating construction.

This is needed to accommodate and measure any foundation movement during the construction works.

All 34 jacks push and keep the walls in their position so the new extension can be built without the danger of the basements' walls collapsing.

In the early stage of the project, at the time the construction procedures and specifications were being defined, ACS one of Spain's largest construction companies and Enerpac developed a 34 point PLC-controlled movement system.

Involving Enerpac at the start of the project means hydraulics and construction experts can work closely together increasing efficiency and adding value to the project.

The Enerpac integrated hydraulic synchronous system measures and monitors any movement of the foundation caused by the load of the surrounding buildings and traffic.

In total 34 double-acting lock nut jacks, each with 500 ton lifting capacity and 100 mm stroke (CLRL-5004) are used.

Each hydraulic jack is equipped with a positioning sensor to measure movement (plunger travel) and a tilting swivel saddle to compensate for side load caused by non-centered loads.

Each group of 17 hydraulic jacks include six Class A 500 ton load cells with an accuracy of 0.1 %.

The hydraulic system with 34 jacks can be synchronized on plunger stroke or load and is controlled by a PLC-remote control unit with touch screen panel.

The real time display of the PLC-control shows the total plunger stroke, relative plunger stroke and total load of each jack individually.

The screen displays the first and second floor level readouts of each group of 17 hydraulic jacks.

Alarms signal when the plunger stroke or load on a jack reaches an unsafe level.

All hydraulic jacks are powered by one large two stage electric pump connected with about 2000 meters of hydraulic hoses.

The PLC control unit includes an emergency stop and extra system safety features to signal voltage and power consumption, pump overload, oil level and temperature.

In the use of hydraulics in heavy construction projects, application knowledge and expertise are very important.

Accurate lifting, lowering or pushing have a significant effect on structures.

Very accurate manual control and monitoring is complex and very time consuming.

And more - accuracy is more important than speed - the advantage of PLC controlled integrated hydraulic systems is enormous.

Every step of the lifting process can be monitored via the display of the PLC control unit.

Apart from the very accurate and stress-free movement of concrete segments, structures, etc Enerpac provides a safe, easy to manage, cost- and laborsaving solution.

Modular air preparation increases reliability

2007-02-10T03:06:00.001-08:00

Parker Hannifin has supplied its Moduflex air preparation system to Hi-Force, the international supplier of high performance hydraulic tools, for use in its air driven pump units.

Parker Hannifin, the world's largest manufacturer of motion and control technologies, has supplied its Moduflex air preparation system to Hi-Force, the international supplier of high performance hydraulic tools, for use in its air driven pump units that complement its hydraulic torque wrenches. Parker's modular filtration system combines high performance with compact design and ease of installation. Hi-Force has been a leading manufacturer and distributor of high pressure hydraulic tools for over 20 years.

The company's extensive product range includes bolting tools and hydraulic torque wrenches specifically designed for accurately tightening and loosening threaded fasteners.

The wrenches require the use of hydraulic pump units, available from Hi-Force as electric and air driven versions.

As the products are used widely in the oil and gas, refinery and petrochemical industries, air driven tools are often preferred over electric.

Kevin Brown, Managing Director of Hi-Force, explained, 'In many cases hydraulic torque wrenches are required to operate continuously, sometimes 24 hours a day, especially during plant maintenance shutdowns, making reliability of performance absolutely essential.

The reliability of air driven hydraulic tools is entirely dependent on a regular supply of clean, lubricated compressed air, making it necessary to include an integrated air line filter, regulator, lubricator and pressure gauge alongside the pump motor.

Conventionally, these elements are bulky, poor quality, difficult to repair and replace, and require additional bowls.' To resolve these problems, the engineering, purchasing, sales and operations team leaders at the Hi-Force head office in Daventry were tasked with finding a more efficient and less problematic solution.

Parker was invited to submit samples of its filter, regulator, and lubricator units to Hi-Force for test and assessment.

Kevin Brown continued, 'The Parker Moduflex system was chosen for a number of unique benefits that it could offer over competing products.

The unit's compact dimensions and modular construction greatly simplifies pipework connection systems, with cast aluminium protection for both filter and lubricator bowls making the product extremely robust.

An integral shut off valve for the air motor was also available which previously had to be sourced and fitted separately.

While price was important, quality of the filters was the key requirement in order to maintain the strength of our global brand and to ensure that there would be no negative impact on sales.' The Moduflex modular system enables combinations of air preparation units to be built in a fraction of the time taken by more traditional systems, thanks to unique 'Cliplok' technology.

Combinations may be assembled quickly and easily, with the individual units combining face to face with no intermediate block and no increase in overall dimension.

Units can be fitted together without the use of pipe connectors, saving space while providing constant mounting centres.

The Cliploks slide into the units from the front and rear and can be locked into place, while Cliploks with integral wall brackets are also available for wall mounting.

The Moduflex series features 5 micron elements as standard, with a 40 micron option where particularly high levels of filtration are required.

Options include coalescing units for the removal of oil and water aerosols, and adsorbers with activated carbon elements for the removal of hydrocarbon vapours.

The one piece body design eliminates the need for a separate bowl, featuring an easy to access base plate for filter element removal.

The element cartridge is a snap fit, one piece cartridge assembly that is easy to remove and replace for servicing with no tools required.

Kevin Brown at Hi-Force is happy with the results, 'Customer feedback on the torque wrenches incorporating the Parker air filtration system has been extremely positive.

As well as the high quality of the Parker products, the company's extensive support network allows us in turn to provide our customers with an excellent level of technical support.

Hydraulic safety examination for tram system

2007-02-10T03:04:00.002-08:00

Thorite has carried out a Written Scheme of Examination on the pneumatic system of the Shipley Glen Cable Tramway, which is located near Saltaire in West Yorkshire.

Leading compressed air products and systems specialists, Thorite, recently carried out a Written Scheme of Examination on the pneumatic system of the Shipley Glen Cable Tramway, which is located near Saltaire in West Yorkshire. The Tramway is the oldest working cableway example in the UK, (cliff lifts excepted). It dates from 1895 and was designed to carry local Bradford workers almost a quarter of a mile through Walker Wood to the attractions of the Shipley Glen beauty spot, the woodland ride providing a pleasant and popular alternative to a steep path.

Thorite's involvement centred on tests and checks of the Tramway's compressed air system.

This operates an automatic emergency brake which acts as a fail-safe device should the trams attempt to travel too quickly.

The system also activates an air brake which is used to park the tram cars.

The Tramway has a gauge of 20', a maximum gradient of 1 in 7 and comprises two tracks with a pair of trams on each line.

The motive power was originally a Suction Gas Engine, but over the years the Tramway has been operated by town gas, then oil in 1915, before being converted to electricity in 1928.

The Tramway is now run entirely by 15 volunteers and unpaid Trustees and will celebrate its 112th Anniversary in May this year, when patrons can ride for the original 1895 fare of a single pre-decimalisation penny to go up - and a halfpenny to come down.

The HSE visited the site and requested the production of an independent Engineering Report highlighting work to be carried out to keep the Tramway in peak condition, which has now been compiled.

With the hard work of volunteers and Trustees, plus specialist local companies like Thorite, the Tramway should continue quietly climbing and descending the beautiful woodland valley for many more years to come.

Nitrogen generator for sports tyres and more

2007-02-10T03:04:00.001-08:00

The Process Filtration Division of Parker Hannifin, the world's largest manufacturer of motion and control technologies, has supplied its TyreSaver nitrogen generator technology to Nexa Racing, the Formula BMW UK Champions. The TyreSaver units are enabling the team to fill their tyres with nitrogen efficiently within particularly demanding timescales, significantly improving their control over their performance on the race track. The Nexa team entered the Formula BMW UK Championship in 2005, going on to win the competition last year.

They attend 10 race meetings a year leading up to the world finals, this year in Valencia, Spain.

With a live audience of 15-30,000 at each race and thousands more on TV worldwide, an outstanding performance at each event is crucial, with no room for error in the preparation and tuning of the cars.

Andy Kidby, Managing Director of Nexa Racing, explained, 'We need to fill the car tyres with nitrogen extremely quickly on race days.

We only get the tyres from Michelin one hour before the cars are due on the track to compete, and we need firstly to remove the air from the tyres and then refill them with nitrogen comfortably within this short time period.

Using nitrogen to fill tyres rather than air enables longer term stability of the tyre pressure to be maintained due to slower leakage, while offering better grip and handling.

The Parker TyreSaver enables us to fill our tyres efficiently while allowing us to retain control of both the purity of the nitrogen and of the tyre pressure, from one race to another.

This was a critical requirement when looking for the right product, as up to 70% of suspension adjustments can be made through adjusting tyre pressure in a racing environment such as Formula BMW.

Tiny changes in pressure can mean the difference between winning and loosing so accuracy in the nitrogen generator is crucial to us.' The TyreSaver is based on Parker's unique hollow fibre membrane technology, which makes it possible to separate a compressed air feed into nitrogen and an oxygen enriched air stream.

Due to their unique composition, the Parker membranes are more efficient than competing materials allowing the diameter of the fibre to be increased, and ultimately resulting in purer nitrogen, and increased on track performance.

With virtually no moving parts, the TyreSaver units offer reliable, trouble-free operation with almost no maintenance.

They can either be connected to an external nitrogen storage vessel or directly to the filling piston, and will automatically switch on and off depending on the nitrogen demand.

The TyreSaver is the smallest tyre filling unit available, making it ideal for trackside use, and is quick and easy to install, with an integrated high quality compressed air treatment unit; alternatively air can be sourced from a dedicated compressor.

The Parker nitrogen generator can achieve competitive results with significantly less air pressure than other methods of nitrogen separation, eliminating the need for expensive compressor upgrades or heaters, lowering operating costs and increasing system reliability.

Andy Kidby at Nexa Racing believes the results speak for themselves, 'Along with being compact and easy to use, the TyreSaver is allowing us to fill tyres incredibly fast, while retaining control and accuracy at all times, effectively offering us another tuning tool.

Radial piston pump is quiet, durable

2007-02-10T03:03:00.000-08:00

The new RKP-II second-generation radial piston pump from Moog provides OEMs and end users with a number of important benefits.

Described as the ultimate in drive technology for stationary hydraulics applications, the new RKP-II second-generation radial piston pump from Moog provides OEMs and end users with a number of important benefits. Of particular interest are those related to noise, durability, efficiency and service life. An increased number of pistons, modified suction porting and redesigned stroke ring enhances fluid delivery, decreases flow pulsation, increases life and significantly lowers noise levels.

Initially available in 63, 80 and 100cc per revolution variants, its radial design offers many advantages compared to axial piston pumps such as low output pressure pulsation.

In most model sizes, an increase in the number of pistons from seven to nine reduces the piston diameter lowering the affect of dynamic transverse forces on the housing.

This means the RKP-II runs virtually stress free and is less subject to piston wear and detaching slipper pads.

Volume, flow and pressure pulsations on the high-pressure side are also noticeably lower.

The RKP-II with its completely re-engineered power train is ideally suited for integration into a wide variety of machines and installations.

According to Moog, these include those involved with tool production, plastic and metal forming, injection and pressure casting, rubber processing, test-bench construction and mining.

It is the pump's design that makes it the number one choice for these noise-sensitive stationary hydraulics applications - the noise intensity for sizes 63 and 80 is <70dB at any working point - allowing the RKP-II to support the implementation of the EU noise guideline 2003/10/EC.

It is designed to be highly resistant to wear and, as a result, is more tolerant of negative suction pressure.

This is due to all the parts associated with fluid flow dynamics being hardened - eliminating pitting caused by cavitation.

Approved for a variety of operating fluids, the RKP-II has a number of control options to guarantee optimum flexibility - no matter what the application.

It has significantly reduced maintenance requirements and its virtually unlimited storage life addresses many issues related to stocking spares - especially important for manufacturing environments that are operating using modern lean principals.

The introduction of a larger suction port (SAE 2' - 3,000psi) together with an improved flow path in the housing and new porting in the journal means the RKP-II can offer extremely robust suction behaviour with optimum intake, less pressure loss along the suction path, lower flow noise and reduced risk of cavitation.

With Moog being a leading manufacturer of servo-hydraulic and servo-electric drive systems for industrial applications, its customers benefit from the company's extensive knowledge of machine integration and system design challenges.

Conveyors benefit from versatile 0.2mm steel belts

2007-01-03T02:01:00.000-08:00

Sandvik Process Systems, a product area within Sandvik Materials Technology and the company behind the world's first steel belt over 100 years ago, is set to expand its presence in the conveying market with the introduction of ultra-thin steel belts that can be employed in applications previously monopolised by plastics belts. The new belt thickness of 0.2mm, together with a belt width up to 600mm, results in a reduced deflection diameter which in turn opens up new opportunities for this proven conveying medium. Among the inherent benefits of steel as a material for transporting goods is its excellent properties in terms of thermal conductivity; corrosion resistance; high tensile strength; high reversed bending strength; hard, smooth surface and resistance to abrasion.

The right balance between these properties can be achieved through careful specification of steel type and Sandvik are widely experienced in designing belts to cope with different and often difficult conditions.

Further Sandvik steel belt applications - mong the choices available to Sandvik's designers are stainless or carbon steels, solid or perforated construction and a smooth or textured surface.

Following major investment in its manufacturing and finishing facilities, the company can produce belts in widths ranging from as narrow as 200mm right up to belts measuring 6000mm wide - with the capacity to supply even larger if required.

This expertise has led to Sandvik steel belts being used in a range of environments from 'pure' conveying applications - including abrasive, hot, corrosive, sticky or pasty products - to instances in which the belt is used to transport goods through different processes.

These can be as diverse as the transportation of car parts through coating lines to bake ovens, fruit and vegetable drying systems and coffee freezers where temperatures can fall as low as -50C.

Food processes are particularly suitable applications for steel due to its corrosion resistance, ease of cleaning and efficient product discharge - essential for products such as chocolate and cocoa mass.

This in-built versatility has led to the steel belt being chosen as the heart of processing systems the world over, in processing plants in the chemical, plastics and wood industries.

Spiral lace fasteners splice conveyor belt quickly

2007-01-01T01:59:00.000-08:00

The non-metallic Alligator Spiral Lace Fastener System offered by Flexco provides a quick-replacement, low-profile, easily separable alternative to costly, high-downtime vulcanized splicing for thin, light-duty conveyor belts. As a totally non-metallic splice, Spiral Lace accommodates applications guarded by metal detectors or X-ray monitors, does not mark or scratch products being conveyed, and provides FDA-approved materials for use in food or pharmaceutical production. Spiral Lace features continuous plastic spirals similar to notebook binding, which are provided pre-assembled into a webbing material.

This assembly is then fabricated into both belt ends through various vulcanizing/bonding processes.

When belt ends are brought together, the spirals mesh and a polyester connecting pin is inserted through the loops to lock the spirals into a hinged joint.

Pre-splicing allows spare belts to quickly replace broken belts without dismantling and reassembling conveyor components.

This is especially helpful where enclosures or tight clearances would otherwise make on-site vulcanization extra difficult.

Easily separated and rejoined by pulling out and re-inserting the connecting pin, Spiral Lace also helps simplify maintenance where frequent cleaning is required.

Spiral Lace is made of polyester in white for belts requiring FDA approval and black for general applications -- both with max.

operating temperatures up to 300 deg F (150 deg C) -- or tan PEEK (Polyether Ether Ketone) for temperatures up to 392 deg F (200 deg C).

Various sizes accommodate belt thicknesses from 1/32in (0.8mm) to 1/4in (6.4mm) with mechanical fastener ratings of up to 50 PIW (8.7kN/m).

The smallest size operates smoothly around pulleys or nosebars as small as 1/2in (12.7mm) in diameter.

Most sizes are offered in continuous rolls 10, 33 or 82ft (3, 10 or 25m) long, in double-web constructions for thicker belts and single-web for thin belting.

Connecting pins in diameters matched to the three Lace sizes are offered in coils 100ft (30m) long.

For faster pin insertion, pins are optionally offered in 15ft (4.5m) lengths tipped with a rigid, smaller diameter 3ft (0.9 m) lead pin that threads more easily through the splice loops.

Improved clipper lacer tool splices belts quickly

2006-12-29T01:57:00.000-08:00

An improved tool for on-site manual installation of Clipper Wire Hook Lacing in light-duty conveyor belts is being introduced by Flexco. While retaining the earlier tool's familiar name, the new Clipper Roller Lacer deeply embeds the belt splice quicker and with less wear on the tool. The lacer head has been completely redesigned for added durability and strength, which enables the Roller Lacer to embed lacing hooks deeper and tighter into the belt.

This lower- profile splice provides greater holding strength, longer service life and less wear on splice-contacting conveyor components.

Lacer guide blocks have been widened to full lacer head width, providing maximum bearing surface for greater wear resistance and minimal maintenance.

Face-strip locking now is done with a knurled knob that allows simple finger tightening in place of the flathead screw that was difficult to reach with a screwdriver.

The new Lacer design also introduces an offset drive handle for greater leverage at one end so more of the splice installation passes can be done conveniently with one hand.

Clipper Roller Lacers are designed for easy on-site splice installation by only one person, lacing even wide belts in a single operation.

Four sizes are available to accommodate belt widths up to 24in (600mm), 36in (900mm), 48in (1200mm) and 60in (1500mm) with a single set-up.

The tool's continuous lacing capability allows the user to lace belts wider than the lacer width.

RFID on semiautomatic pallet stretch wrappers

2006-12-21T02:47:00.000-08:00

Lantech is introducing RFID tag-reading capability as a standard option on all its semiautomatic pallet stretch wrappers. The company demonstrated a working system at Pack Expo on a Q-300 semiautomatic stretch wrapper utilising Symbol Technologies' new RD5000 portable reader. Capable of reading Gen 1 and 2 tags, the battery-powered system can read tags at the pallet or case level.

'We are now offering this system as a standard option on all our turntable stretch wrapping systems, and will migrate quickly to our overhead straddle stretch wrappers as well,' said William Caudill, Lantech's marketing manager for automatic stretch wrapping products.

'The portable and wireless RD5000 is the most elegant, hands-off RFID solution currently available for this application.

We have already quoted systems to the largest consumer goods maker in the US, and we expect interest to build in 2007.

As a simple drop-in option, it eliminates all brackets, cables, external antenna and any interface to the machine or control system, working independently of the machine with its own motion-sensing.' The compact reader measures just 7' x 9' x 2' (LWH) and weighs less than four pounds.

Although it is battery operated, Caudill says the system can be wired to the machine's power supply as a customer option.

The RD5000's integrated wireless LAN is compliant with 802.11a/b/g standards, allowing it to communicate with any standard WiFi network.

The unit is sealed to an IP66 rating against water jets and dust, and runs under the Windows CE operating system for robust application support.

'Our development machines with the reader mounted on the film delivery system have proven that stretch wrappers have a natural advantage in tag reading by repeatedly exposing five sides of a pallet load to the reader's antenna,' added Caudill.

'The wireless, portable design of this unit makes it a great retrofit solution, too, because there is no interface or power connection of any kind between the stretch wrapper and the RFID reader.' Lantech currently has development systems at Exel, Kimberly-Clark, Alien and Wal-Mart-related facilities.

'In collaboration with our industry partners, we're evaluating the most appropriate methods for an industry-standard RFID implementation so that our customers will benefit from products that have been tested and proven successful in real-world applications,' Caudill stated.

Lantech's economical Q-300 semi-automatic stretch wrapping system is an ideal RFID-development machine, with capability for processing 25-35 loads per hour up to 2 m (80') tall and weighing up to 1814 kg (4000 lb).

The machine's electronically controlled, variable wrap force and 200% pre-stretch on the film ensure consistent, tight loads with economical use of film, reduced labor and improved ergonomics.

Pre-stretch up to 300% is available as an option.

The Q-300 features Lantech's patented Power Roller-Stretch system and E-Z Threadandnumber129; roll carriage to make film-threading safe, easy and consistent, reducing the chance of mis-threading and ensuring the highest film yield.

The Q-Series of turntable stretch wrapping systems also includes low-cost automatic models for affordable automation, and high-speed automatic models designed for high throughput or fully automatic operations.

Latest roller chain offers 100% more wear life

2006-12-20T02:48:00.000-08:00

Tsubaki's groundbreaking 'seventh generation' ANSI standard chain employs an innovative bushing system that greatly improves internal lubrication and extends wear life by 100% in the most popular RS80 to RS140 sizes. A combination of the new 'lube groove' bushing and an exhaustive testing regime also means that the new ANSI standard RS roller chain has a 33% higher kW rating. The new 'G7' chain was launched across Europe during October 2006.

Independent testing and field data show that wear in the pin/bushing joint is usually the limiting factor in overall chain life, particularly in externally lubricated chain types such as ANSI standard roller chain.

(The chain bushing is located between the solid bearing pin and external roller).

Tsubaki has committed a significant amount of its research and development resources to making improvements in this area, to reduce wear and effectively prevent chain elongation over a longer period of time.

The result is a patented lube groove bushing, the grooves themselves providing an internal reservoir for lubricant where the chain needs it most, which has a dramatic effect on both chain performance and longevity.

Tsubaki's G7 bushings utilise a new production technique to enable a series of grooves to be incorporated on the inner surface of a cold forged, extruded bush.

The new process results in a very precise cylindrical profile for better surface contact between the pin and bushing, and improved lubricant retention.

The patent design lube groove bush (LG) ensures that the chain is optimally lubricated, particularly in real world conditions where inconsistent external lubrication is a factor.

The result is a chain that lasts significantly longer in the field.

When tested, G7 chain lasted twice as long as Tsubaki's previous generation ANSI chain - and up to 4x longer than some comparatively priced alternatives from leading US and European competitors.

Increased wear life equates to lower maintenance costs, reduced downtime and increased reliability.

Overall equipment efficiency (OEE) costs are also reduced since the purchase cost is offset over a longer period of time - the price of G7 chain is unchanged over that of the previous generation.

As OEE costs feature more frequently in company thinking the evidence is building up to show that the cheapest chain is not always the cheapest solution and that higher quality products can significantly reduce costs.

Rigorous testing has also resulted in an increased kW rating - 33% higher for all chain sizes in the range from RS80 to RS240.

Only recently have ISO standards for fatigue testing link plates included a cyclic fatigue test, rather than a test just for linear tensile strength.

ISO requires a 5million cycle test, Tsubaki test to 10 million cycles, resulting in a higher kW rating for the Tsubaki G7 chain.

Customers can now benefit from enhanced power handling capability and an extended service life, or in some circumstances a more compact and less costly chain installation, the former being of more relevance to maintenance and replacement applications and the latter to OEMs.

A number of other innovations also contribute to this performance improvement.

Rollers are heat-treated and shot peened to give added durability and fatigue life in high-speed applications.

Second hand weighing and packaging

Tsubaki UK has launched a new range of high quality, high precision power jacks for lifting and actuation tasks in all areas of industry and commerce.

2006-12-18T02:46:00.000-08:00

Coca-Cola have recently benefited from a survey of all the transmission and conveyor chain used on machinery at its bottling plant at Enfield, North London. The Enfield site is one of the largest bottling plants in the UK and is capable of filling a staggering six million bottles a day containing 12 million litres of various drink products. The survey was conducted by engineers from Renold Chain as part of the company's free Site Survey service in which every chain at the plant was meticulously photographed, Catalogueueueueued and given a unique code number.

The information was stored on CDs kept by both Coca-Cola and Renold.

When a chain needs to be replaced all the maintenance team at Coca-Cola will need to do is look up the chain in the list and order a new one by quoting its unique code.

A new chain of the correct size and type is then supplied with any attachments that may be applicable.

During the survey at Coca-Cola Renold's engineers made an expert analysis of the size and type of chain on every application and made recommendations for improvements where appropriate.

A number of chains were identified as suffering from premature wear resulting from drink spillages that were removing lubricant before it could penetrate the pin and bush.

These chains have now been replaced with Renold Syno, a high-tech chain with lubricant held in a specially designed sintered bush.

Lubrication is released in precisely the right amounts needed and directly onto the components of the chain that need it.

Relubrication of Syno chain is not necessary during its lifetime and its smooth operation is not affected by drinks spillages.

So satisfied were Coca-Cola with initial successes that they have now upgraded to Renold chain throughout the plant.

Power jacks for lifting and actuation tasks

2006-12-17T02:45:00.000-08:00

Tsubaki UK has launched a new range of high quality, high precision power jacks for lifting and actuation tasks in all areas of industry and commerce. The comprehensive Linipower range, with three model types, and supported by a wide range of options and accessories, delivers solutions in key sectors such as medical, industrial, transport, liquid crystal/PDP manufacture, telecommunications and entertainment. Providing constant high performance, precision and reliability even under demanding application conditions.

The Linipower jacks are the result of cutting-edge technology developed by Tsubaki's Emerson division; acquired through years of experience as a leading manufacturer of electro-mechanical actuators.

They are high quality units that are thoroughly tested and environmentally engineered to ensure consistent high performance and safety for the user.

Robust in design, the Linipower jacks offer lift capabilities in the range 1.96kN to 980kN; strokes to 2 metres; and the flexibility to be installed horizontally, vertically or inclined.

They can be supplied as individual items, or as motorised systems employing matched standard or specialised gearmotors, space-saving hypoid motors or servomotors.

The jacks also offer the user options such as an LD function for excellent low dust performance, and safety caps to protect personnel from possible injuries.

The standard base model in the Linipower range is the JWM series, a simple, compact and affordable machine screw jack that integrates a trapezoidal screw and high precision worm gear, making it highly suitable for low speed, low frequency operations.

The unique sliding motion of the trapezoidal screw provides smooth and consistent low speed performance, while an integrated Self-Lock feature maintains load, obviating the cost and time of installing a brake unit in the majority of applications.

Offering the highest capacity (908kN) in the Linipower range, the JWB ball screw type jack is a highly efficient unit for high speed, high frequency operations.

The compact drive produces high power, while its ball screw technology delivers long and predictable life, and also high efficiency, which, when compared to the JWM, allows a higher speed drive.

For applications where speed rather than lift capacity is the major requirement, the Linipower range offers the JWH high lead ball screw type jack.

Depending upon the lead used, the screw shaft speed of the JWH jack can exceed that of a JWB by up to 4 times, at the same input shaft rpm; reaching maximum screw shaft speeds of up of 7.5m/min.

Importantly, despite its higher speed performance, the JWH is actually quieter than the JWB jack, as it requires less input rpm at its drive and reducer units to run at the same speed.

Completing the Linipower range is the LD (low dust) type jack, which is an excellent choice for use in clean rooms such as those serving FDP (Liquid Crystal/PDP) manufacture, and bearing assembly.

This model regulates dust generation resulting from wear, as well as dust produced from the screw.
