Abstract:
An improved drop-bed trailer provides a trailer without ramps that lowers to the ground, enabling one person to load/offload motorcycles, etc. A trailer frame with independently pivotal elongated members on each side of the frame, a wheel on each elongated member. A rubber spring or steel coil spring suspension system on the end of each elongated member. A winch and cable pulley system connected to each end of the elongated members via cable connector fitting through the two snap-in bushings. Cable retrieval upon the winch causes the elongated members to be drawn parallel to the frame in raised locked position. A cable tension device keeps the primary cable uniformly coiled upon the winch while providing slack to the secondary cable for complete compression of the suspension system. A safety restrictor device is mounted to the trailer frame to limit the pivotal movement of the elongated members in the event of a cable mechanism failure.
