ABSTRACT:
A lightweight, movable lift usable in pairs for lifting and rotating vehicles to allow easy access to their undersides and engine compartments. A frame and upright slidably support a carriage which is moved up and down the upright by an actuator such as a hydraulic cylinder, compressed air cylinder or mechanically operated jack screw. A vehicle support rack is connected to the underside of each end of the vehicle and to a journal such that the journal is substantially aligned with the center of gravity of the vehicle. The journal is rotatably borne by the carriage as it moves up and down the upright, whereby the vehicle may be easily rotated once it has been lifted a sufficient distance. A follower mounted an appropriate distance radially from the center of rotation of the journal is received and controlled by a follower track mounted on the upright to rotate the vehicle as it is lifted. The lift allows the vehicle to be rotated a full 90 degrees when lifted for easy access to its underside.
