  • Patent number: 5156238
    Abstract: A portable surface lift for a vehicle and retractable spring-loaded wheels attached to the lift for rolling the lift over a garage floor surface when the vehicle is not lifted on the lift. The lift has various adaptor pads for contact with the undercarriage of the vehicle, and a hydraulic cylinder raises and lowers the vehicle on the lift. The spring-loaded wheels extend and raise the lift from the floor for movement when a vehicle is not on the lift, and retract to allow the lift to rest on the floor when the vehicle is lifted. Three towing mechanisms are provided for moving the lift: a bar that can be attached to an automobile floor jack, a towing dolly, and a towing apparatus. The towing apparatus allows a towing bracket on the end of the lift's base to be reached beneath a long luxury vehicle. The lift may be rolled under and from a stationary vehicle, and has a safety locking mechanism for securing the lift in various raised positions.
