摘要： A rail road car has a deck for carrying wheeled vehicles. The vehicles are loaded from the ground by use of a movable ramp that is positioned next to a separate coupler end of the rail road car. The ramp has a locating guide, in the nature of a pair of tapered prongs, that locate in mating sockets in the end of the rail road car. The co-operation of the guides and sockets forces the ramp to align with the deck of the rail road car in a predetermined position, namely aligned centrally with the deck. The ramp has a telescoping, pivoting boom. The boom has a hitch that can be engaged by a towing vehicle, permitting the ramp to be moved into position as desired. The boom can then be collapsed and lowered out of the way of the path of the wheeled vehicles. The boom is counterweighted to facilitate manual operation.

摘要： 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.

摘要： A truck leveler includes a low-profile traffic surface that is pivotally mounted to a driveway approach in front of a loading dock. Pivoting the leveler raises a reat portion of a truck or trailer to the height of the dock. The truck leveler has strength, rigidity and accommodates a retractable or repositionable wheel restraint while maintaining its low profile. This is accomplished by virtue of a raised rear beam and two lateral beams that extend above the traffic surface of the leveler. A central beam allows field assembly of the leveler while adding further to the leveler's strength and rigidity.
