Hydraulic Vertical Lift

A hydraulic lift is a device for moving objects using force created by pressure on a liquid inside a cylinder that moves a piston upward. Incompressible oil is pumped into the cylinder, which forces the piston upward. When a valve opens to release the oil, the piston lowers by gravitational force.The hydraulic lift is an elevator which is operated by fluid pressure generated by a suitable fluid. It is used to raise automobiles in service stations and garages. In a hydraulic lift, two pistons are separated by the space filled with liquid.
