How does a hydraulic lift gate work?
When the control box switch is turned to the DOWN position, the lowering valve coil is activated, allowing fluid to flow from the cylinder back into the reservoir . This releases pressure on the cylinder piston, enabling the liftgate platform to lower by gravity.
How does a hydraulic dump pump work?
A dump pump as used on a typical dump truck in N.A., is a combination of a hydraulic pump, a pressure relief valve and a directional control valve in one housing. When the pump input shaft is rotated, the gears create a low pressure area that is filled with fluid from the reservoir.
