Dock levelers bridge the gap and height difference between the dock and the trailer. They also compensate for the up and down float of the trailer bed during loading. A dock leveler includes a ramp (hinged along its rear edge) and a lip (hinged at the front of the ramp). When not in use, the dock leveler is stored in its neutral position, flush with the loading platform floor. To use a dock leveler, the operator raises the ramp and the lip swings out. With the lip extended, the operator lowers the ramp until the lip rests on the truck.
