ABSTRACT:
A dock leveler includes a ramp movable between a raised position and a lowered position in response to selective inflation of an inflatable member disposed between the ramp and a support located below the ramp, and an improved mounting arrangement for securing the airbag in position below the ramp. The improved mounting arrangement includes a flap extending from the airbag, which preferably consists of extended portions of the airbag walls extending outwardly from an edge defined by one or more internal airbag cavities. The flap is folded and preferably sealed about a rod, and a clamping arrangement is engageable with the flap between the rod and the airbag internal cavities for securing the airbag to a mounting surface, such as a surface defined by the support with which the airbag is engageable. The clamping arrangement includes a clamp bar having a clamping member engageable with the airbag, a spacer mounted at an end of the clamp bar opposite the clamping member, and a series of threaded members such as bolts extending between the clamp bar and the support for removably securing the clamp bar to the support.
