Abstract
A hydraulic jack system is described, suitable for lifting heavy loads such as automobiles. The jack system is operable by a powered driver fitted with a socket for coupling to a nut rotationally fixed to the jack system, wherein the driver is removable directly after use. As such, no handle is required for activating the hydraulic jack system. The jack system has a low profile, reducing the danger of being accidentally knocked into during operation. When operated by a powered driver, the driver rotates a camshaft mounted to the jack system, the camshaft reciprocally drives a push rod that activates a plunger for hydraulically elevating a piston ram.
