ABSTRACT:
An inflatable bag assembly for a dock leveler including a stack of superimposed bags which are joined together along contiguous surfaces. The interiors of the bags are connected to a suitable source of low pressure gas such as air. The stack of superimposed bags is positioned between a supporting surface on a loading dock and a ramp which is hinged to the dock and is movable between a horizontal position and an upwardly inclined position. By supplying air to the bag assembly, the bag assembly is inflated thereby moving the ramp from the horizontal to the upwardly inclined position.
