ABSTRACT:
A loading dock leveling apparatus including a ramp pivotable about its rear end and having a pivotable lip on its forward end. Apparatus is provided for projecting the lip outwardly after the ramp is raised beginning when the ramp is walked down to provide that the lip will engage the bed of a vehicle to be loaded or unloaded. The projecting apparatus includes a knuckle joint which pivots to projecting position on the ramp upswing and which is subsequently pivoted by a lever to release the projecting apparatus during the walk down but before the ramp descends to the highest serviceable vehicle level. A lip lock is provided for holding the lip in its projected position until the lip rests on the bed of the vehicle to be unloaded or until the ramp passes well below dock level and the lip lock is disengaged by a lip lock release.
