Abstract
Abstract A ramp apparatus which provides access from a pier to a moored floating dock. The ramp is attached at its upper end by means of a double gimbel joint so as to permit the lateral and vertical motion of the dock and ramp. The lower end of the ramp is provided with wheels for permitting limited motion of the ramp over the dock surface. Also disclosed is a means for providing additional stability for the ramp particularly for wider ramps.
