  • Patent number: 5377782
    Abstract: A short-rise lift apparatus is provided which is convertible between a first construction in which a vehicle is lifted directly by a platform that is raised against the body of the vehicle, and a second construction in which a plurality of lift arms are interposed between the platform and the frame of the vehicle so that the vehicle is lifted by the frame when the platform is raised. The plurality of elongated lift arms are retained on the platform and may be translated longitudinally relative to the platform and pivoted about a vertical axis. Each lift arm is removable from the platform so that when the lift arms are removed and the platform is moved toward the raised position, the platform engages the body of the vehicle and lifts it.
