..., and a hydraulic cylinder with the piston connected to the ram. The cylinder is usually double-acting—that is, oil is pumped under pressure into the top, above the piston, to make the ram move down; to make it move up, oil is pumped into the bottom, under the piston. With oil under pressure both above and beneath...
