Bumpers are mainly used in vehicles to absorb any impact and to prevent vehicle from getting damaged. During loading & unloading between the vehicle & dock, the vehicle should not move and in case of any movement the bumper absorbs the impact from backing up to the dock. The bumper dimensions are determined by the opening size, the loading area shape, the distance between the rear of the vehicle and the rear wheel center. The bumper is also used with a yard jockey tractor where slope of the trailer is increased as the yard tractor lifts the front of the trailer higher than the normal over the road tractor.

Dock levelers are an adjustable ramp either part of a vehicle or built in to the lip of a loading dock that compensates for differences in height between the dock and vehicle bed. Dock levelers are typically installed to the flush with the floor of the dock when retracted. The levelers are activated or retracted by spring pressure or hydraulic. Dock levelers are reinforced steel plates, which are manually lifted in to place to form a bridge. Factors used in selecting the appropriate dock leveler include the weight of the heaviest lead and materials handling vehicle combination to cross the distance which the unit must span for bridging and the combined width of the load and materials handling vehicle.
