Abstract: A dock bumper is provided. The dock bumper includes a housing holding a plurality of rollers arranged in an array. The plurality of rollers are arranged to absorb impact from a reversing vehicle. Upon impact, outer surfaces of the rollers are arranged to rotate relative to the frame. Consequently, scrubbing between the vehicle and dock bumper is reduced as are excess forces acting on fixings between the frame and wall. Also, a surface area at each contact location is increased as a cushioning effect is provided by rotation of the roller, thereby prolonging the operation life of the rollers. Furthermore, in one form, the dock bumper is modularized so that only worn or damaged rollers need be replaced at one time.
