ABSTRACT:
A support and attachment mechanism for a dock leveler lift bag. The dock leveler includes a supporting structure which is mounted in a pit in a loading dock and the rear end of a ramp is pivoted to the supporting structure so that the ramp is movable between a horizontal position and an upwardly inclined position. A bag support member is pivoted to the supporting structure and is located in the pit beneath 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 to the upwardly inclined position. The bag assembly includes a rearwardly extending tether which is secured to the supporting structure and prevents the bag assembly from squeezing forwardly as the bag assembly is inflated. The deflated bag assembly can be drawn upwardly against the underside of the ramp by pivotal movement of the bag support member to provide access to the pit.
