ABSTRACT:
An improved support and attachment mechanism for a dockleveler lift bag. The dock leveler includes a supporting structure or frame which is mounted in a pit in a loading dock and the pit has a forwardly sloping floor. The rear end of the ramp is pivoted to the supporting structure, so that the ramp can be pivoted between a horizontal position and an upwardly inclined position. A bag support member is located in the pit beneath the ramp and is pivoted to the rear end of the ramp. An inflatable bag assembly is located adjacent the rear end of the ramp and is positioned between the underside of the ramp and the bag support member. By inflating the bag assembly, the ramp can be pivoted from the horizontal position to the upwardly inclined position. Guide members, such as rollers, are mounted on the forward end of the bag support member and ride on the floor of the pit as the bag assembly is inflated and the ramp is pivoted upwardly.
