Abstract:

A surface supported vehicle lift includes at least one independent elevating runway member which accepts loads of varying weights. The runway member accepts uniform or non-uniform loads imposed from a first end to a second end. The runway member includes at least two lift leg assemblies. The lift leg assemblies include hydraulic cylinders and a pump having an electric motor to drive the hydraulic cylinders. Each lift leg assembly also includes pulsed or proportional solenoid valves and position sensors affixed thereto. Synchronizer pumps are provided to equalize flow to and from each lift leg assembly for the runway member, and each lift leg assembly includes pulsed or proportional flow divider bias thereby maintaining lateral and longitudinal synchronization between each lift leg assembly. The surface mounted vehicle lift need not be fixedly attached to a supporting surface, and in addition, may be in moveable contact with the supporting surface. As desired, a guiding means for provision of a specified elevation path may be provided.
