Hydraulics moves the ramps and platforms that allow a single carrier to hold multiple cars. Naturally, heavy loads are involved, and the hose must tolerate brutal over-the-road conditions. Typically, car carriers have relied on SAE 100R1 hydraulic hose for pressures to 2250 psi for 3⁄8-in. hose (to 2000 psi for 1⁄2-in. hose) and SAE 100R2 for pressures to 4000 psi for 3⁄8-in. hose (3500 for 1⁄2-in. hose). However, the pressure rating for one manufacturer’s proprietary hydraulic hose is 2750 psi for the 3⁄8-in....More
Accumulators are among the most beneficial but unheralded components of a hydraulic system. They perform several useful functions, not the least of which is energy savings. Piston and diaphragm accumulators are the most common, but when application conditions become especially hostile, a metal bellows accumulator may be called for....More
The ability to set the overlaps at each valve land individually offers an opportunity to gain insight that would not be practical with real valves. Whereas previous simulations have all dealt with perfect symmetry in all the lands, such an idealized condition can never exist in any practical way, due to manufacturing (such as flow grinding) tolerances....More
Hydraulic drives often are combined with gearing to provide the best combination of output speed and torque for maximum efficiency, performance, and controllability. But sometimes hydraulic actuators are best used when they are integrated into a gear drive. Hydraulically actuated clutches, for example, can be used within a gearbox to engage and disengage different sets of gears to provide different output speeds and torques....More

Officials at a stainless steel rolling mill purchased an old but well-built plate stretching machine. They had us strip the machine of all the hydraulic and electrical controls because they wanted us to design and install new hydraulics and a PLC to control the stretcher. This machine would clamp both ends of a 12 × 20 ft stainless plate they had heated and rolled to a thickness that could be up to 1½ in. thick. The process of heating and rolling to size caused the plate to warp, making it look like the waves of an ocean....More
