Hydraulics

In order to generate massive force, you must apply pressure to a large area. The trade-off is that the larger the area that is being acted on, the more flow (volume) it takes to get an actuator to move a given distance. If you want a cylinder to generate massive force and move quickly, you will need a massive prime mover.

Mobile machine operators can frequently find themselves operating the business end of their machine without direct control. This is a safety and operational hazard that can be easily fixed with radio frequency remote controls. Luckily enough, their implementation is fairly straight forward.

With today’s ever changing demands on hydraulics and the advent of new Tier 4 engine, the need to vary the input torque of hydraulic pumps becomes evident. Using the Power Shift regulator, input torque to the pump can be limited to prevent engine overload and stalling at varying engine speeds and output power. Optimizing the horsepower input demands of the pump can result in significant savings in fuel consumption and emission output.

If someone talks about an “open loop” or “closed loop” hydraulic system, what exactly do they mean? Fundamentally, the difference can be described in just two sentences, and is most easily defined by the pump:

All hydraulic components have ISO codes, but many people don't understand them. ISO codes rate the cleanliness of your hydraulic oil so that you can properly maintain your machine. Ignoring them would be a critical mistake.
