Abstract
A dock leveler has a deck pivotally mounted to a frame. A counterbalance mechanism uses a pair of pivoting links connected together at a common point with a tension spring that is coupled at the other end to the deck. The links together with the frame and the deck form a four-bar linkage biased by the spring to counterbalance the weight of the deck.
