Abstract
A dock leveler assembly for a loading dock is provided having an adjustable ramp, a pivotally mounted lip and a pivotally mounted barrier plate both disposed at front edge portion of the ramp. The pivotal movement of the lip and the barrier plate are coordinated so that, when the lip is in a depending stored position, the barrier plate may be selectively adjusted to assume either an operative upwardly projecting vehicle barrier mode or an inoperative non-projecting mode allowing material handling equipment to load or unload the rear end of a vehicle parked adjacent the loading dock. When the lip is in an operative cantilevered position bridging a gap formed between the ramp front edge portion and the bed of a parked vehicle the barrier plate assumes the inoperative mode allowing material handling equipment to pass over the ramp and the lip onto the bed of the parked vehicle during loading and unloading thereof.
