Abstract
A dock leveler comprising a ramp hinged at its rear end to a supporting structure and movable between a generally horizontal position and an upwardly inclined position. A lip is hinged to the forward edge of the ramp and can be pivoted between a downwardly hanging pendant position and an extended position. Interposed between the ramp and the supporting structure is an inflatable bag, while a second inflatable bag interconnects the ramp and the lip. Blowers mounted beneath the ramp supplies low pressure air to both bags, and inflation of the first bag will move the ramp upwardly to the inclined position, while inflation of the second bag will move the lip from the pendant to the extended position.
