ABSTRACT:
An auxiliary loading dock ramp is provided which can be securely locked to a conventional ramp so as to increase the overall length of the ramp surfaces thereby lessening the degree of incline of the ramps between a loading dock and a truck or railroad car. The auxiliary loading dock ramp includes legs on the forward end thereof and support means on the rearward end thereof to maintain the ramp in an elevated position above the surface of the loading dock, and channel members on the underside of the deck of the ramp to receive the forks of a pallet jack employed in moving the auxiliary ramp into position. A pair of ears on each side of the auxiliary ramp adjacent the rearward end thereof are received in slots in the forward end of a conventional ramp such that the forward end of the conventional ramp overlappingly engages the rearward end of the auxiliary ramp to provide an elongated deck surface over which loads may be transported between the loading dock and the truck or railroad car.
