2013 Manufacturers' Index
The following is a list of all manufacturers who provide product information and specifications in our Designer's Guide. Advertisers in our January 2013 issue are in bold. Click here for a complete list of all Designer's Guide charts, which are a collection of specifications for a variety of popular categories of fluid power products and services. Several hundred companies are represented. Charts and index listings were prepared from information supplied by those companies directly to the editors of Hydraulics & Pneumatics.
Bet you can’t read just one
Editor Alan Hitchcox talks about the longevity of Hydraulics & Pneumatics' technical content and how readers often look for articles that are decades old because they are still relevant today.
LDT lets RoGator adapt to the task at hand
When it comes to versatility, machines don’t get much better than the RoGator, manufactured by AGCO Corp., Duluth, Ga., at it’s facility in Jackson, Minn. Three sizes of RoGators all come with a 4-wheel hydrostatic drive system and closed-loop electrohydraulic steering that provides 2-wheel steer, all-wheel steer, auto steer (which provides 2-wheel steer until the front wheels pivot 6° or more, at which time 4-wheel steer automatically kicks in), and crab steer.
Hydraulics handles the hassle of hauling helicopters
Helicopters rise straight up when they take off. That’s the beauty of these aircraft, they don’t need a long runway to become airborne. And because of this, the majority of helicopters (except for some larger models) are manufactured without wheels. They are fitted with landing skids instead.
The future of fluid power?
Don’t look at me; your guess is as good as mine. But I think we all would agree that fluid power is a mature industry that goes through incremental advancements. Digital microprocessors have made huge contributions to automated control, and new component designs and manufacturing techniques have advanced the physical capabilities of both hydraulic and pneumatic systems.
All bets are on for a great experience
Once every three years, the Las Vegas desert plays host to thousands of users and makers of fluid power components, and this time around, the IFPE 2011 International Exposition for Power Transmission promises to be bigger and better than ever. The show and conference, both of which highlight fluid power, power transmission, and motion control, will once again be co-located with CONEXPO-CON/AGG, one of the world’s largest construction equipment trade shows. Both events will be held March 22-26, at the Las Vegas Convention Center.
Regenerative circuits made easy
Regenerative circuits save time and energy by increasing the extension speed of double acting cylinders. They do this by routing fluid exiting the rod end of the cylinder back to its cap end instead of routing the fluid to tank.
Flow control valves are efficient and versatile
Closed-loop electronic control systems exhibit the cutting edge of mobile electrohydraulics. But their price tag is prohibitively high for applications that don’t require such high precision and intelligent control. An example is the CV 2000 load-sensing, post-compensated sectional control valve from Nimco AB, Malmö, Sweden. The CV 2000 LS can be used in systems with both fixed and variable displacement pumps. The compensators in the sections allow all functions to work even when the pump is saturated.
Accumulators beat boom bounce
Designers at a manufacturer of agricultural equipment eliminate the problem boom bounce on their self-propelled, high-clearance sprayers with AccuMight bladder accumulators.
Fluid warmers boost machine productivity
Hydraulic fluid tends to thicken as it gets colder, which hinders it from flowing into a system’s hydraulic pump. Restricting flow into the pump can create cavitation, which, in turn, leads to premature pump failure. On the other hand, waiting for fluid to warm up enough to run a machine’s hydraulic system keeps equipment and work crews from doing any work.
Filtration for servo systems
The most effective way to reduce life cycle costs of an oil hydraulic system, regardless of the types of valve used, is through close attention to contamination control.
Hydraulic motor inside
A conventional conveyor system uses an externally mounted electric or hydraulic motor to drive the conveyor’s head pulley. A hydraulic motor can extend up to 20 in. from the end of the pulley. In addition to taking up space, the motor can be in the way of equipment and personnel, causing damage or injury. The motor also requires a shaft coupling or chain drive that can be hard to keep clean and require maintenance.
Dealing with overhung load
Whether input power comes from an electric motor, gasoline or diesel engine, or PTO on a transmission, hydraulic pumps typically are driven through an industry-standard flange. This arrangement ensures that the mating shafts are always aligned and that no side load is transmitted to the pump’s input shaft.
