发明名称 REMOTELY CONTROLLED EXTENDABLE LIFT APPARATUS FOR A VAN
摘要 An extendable lifting apparatus for a vehicle. The apparatus includes a support bracket secured to the floor of the vehicle. A tube is mounted to the support bracket perpendicularly to the axis of the vehicle frame. The tube receives a boom which is used to support a cable used to lift heavy objects. The tube is substantially rectangular and has an axial slot extending along the bottom to form an axial opening that allows the cable to be suspended therein when the boom is in the fully retracted position. The slotted wall of the tube also acts as a floor opposite an inner ceiling. A winch is coupled to the boom for successively winding and unwinding the cable. A motor is coupled to the tube for moving the boom from a retracted position wholly within the tube to an advanced position. A second motor is coupled to the winch for controlling the winding and unwinding of the cable. Control of the two motors is provided by a remote control. Finally, a brake is provided for preventing the unwinding of the winch allowing a suspended object to freefall when the second motor experiences failure.
