ABSTRACT:
A lift for motor vehicles using hydraulic cylinders powered by a remote electrical hydraulic pump. The hydraulic cylinders lift pistons having an upper distal area adaptable for receiving the payload vehicle. The pistons are rigidly linked to each other at their lower proximal ends by an equalizer beam. The upper distal area of each piston includes a mounting plate for accepting a lifting platform for bearing the payload vehicle. The pistons of the lift raise the payload vehicle using the hydraulic cylinders in connection with a series of chains and pulleys. The pulleys are mounted on the hydraulic cylinders. The chains are attached from an upper chain anchor at the top of the lift structure, to the pulleys on the hydraulic cylinder, and to a lower chain anchor on the equalizer beam. Each hydraulic cylinder is contained within a sleeve fixedly mounted to a cylinder mount post. As the hydraulic cylinders are moved in a vertical direction by the hydraulic pump, the chain and pulley systems force the pistons to move in a vertical clockwise direction in unison.
