Abstract
A dock leveler including a ramp having a rear edge movably interconnected with a loading dock, an intermediate member movable relative to the ramp, and an inflatable assembly positioned to cause relative movement between the ramp and the intermediate member upon inflation of the inflatable assembly, thereby resulting in movement of the ramp. The intermediate member is movably mounted to a pit floor, a support structure, or the ramp. A roller member is mounted to an end of the intermediate member. The inflatable assembly can be operatively associated with a vacuum device to allow for selective removal of gas from the inflatable assembly. Alternatively, a hydraulic assembly and a support frame may replace the inflatable assembly and intermediate member. The dock leveler includes hook-type bracket members and mounting bores to accommodate either powering arrangement.
