Abstract

A dock leveler with run-off barrier configuration is disclosed in two embodiments. In a first embodiment, the dock leveler includes a faceplate, a deck, and a lip with the faceplate mounted on the end of a dock, the deck pivotably mounted to the faceplate and the lip pivotably mounted to the deck. The deck is pivotably mounted to the faceplate via a first linkage including two legs pivotably mounted to each other as well as to each of the faceplate and the deck. The faceplate and the lip are interconnected with a second linkage including two arms pivotably connected together and pivotably connected to each of the faceplate and the deck, respectively. Gussets are provided on a portion of the faceplate and include recesses terminating in upwardly turned detents. In one configuration of the dock leveler, the termination edge of the lip may be received within the recesses in the gussets so that the deck portion acts as a sturdy barrier. In a second embodiment, an actuating lever is mounted under the deck and has an interconnection with the second portion of the faceplate via a flexible connector such as, for example, a chain or cable.
