Abstract
Bumpers for use at loading docks include a housing defining a lip-engaging surface to engage a lip of a deck when the lip is in a retracted position, and a RIG-engaging surface positioned adjacent the lip-engaging surface. The RIG-engaging surface is movable relative to the lip-engaging surface. The RIG-engaging surface is to move relative to the lip-engaging surface when a RIG of a vehicle imparts a force to the RIG-engaging surface when the vehicle is at a loading dock.
