ABSTRACT:
A dock leveler assembly is provided having an automatic barrier actuated in response to movement of the lip for preventing accidental runoff of material handling vehicles from the loading dock. The assembly includes a ramp for pivotal movement between a stored first position wherein an exposed surface thereof is coplanar with the loading dock platform surface, an upwardly inclined second position, and a declining third position. The lip is operatively connected to a front edge portion of the ramp for movement from a depending position to an outwardly extended cantilevered position. The assembly also includes a barrier unit movable between operative and inoperative modes. When in the operative mode, a segment of the barrier unit automatically projects above the ramp exposed surface and forms a vehicle safety barrier of optimum height.
