  • Publication number: 20070040405
    Abstract: The powered ramp door lift is used in cargo trailers and other ramp door applications and includes a powered winch assembly, a pair of wire cables or nylon straps connecting the winch assembly to the ramp door, and a “pusher” mechanism. The winch assembly mounted to the trailer header winds and unwinds the cables onto a pair of spools mounted to a drive shaft, which is driven by an electric motor. The “pusher” mechanism prevents the “unspooling” problems that effect the operation of winches in automated ramp door applications. The pusher mechanism engages the ramp door in the closed position and applies an outward force to the ramp door over a small portion of its travel to assist in the initial lowering of the ramp door from the closed position. The winch assembly also includes a cable tension winch shut off mechanism, which deactivates the winch motor in the absence of any tension on cables.
