ABSTRACT:
A dock leveler including a ramp is movable to a raised position by inflation of an inflatable member, such as an air bag assembly. One or more filler members are located within an internal cavity defined by the air bag assembly, to occupy void volume therein. The filler members expedite inflation of the bag assembly when an inflating device is operated to introduce air under pressure into the bag assembly. The filler members also function to maintain the bag assembly in an engaged condition with the underside of the ramp, and to prevent the air bag assembly from fully collapsing in order to prolong bag life.
