Loading dock bumpers are designed to stop an incoming truck and prevent damage to the building. When the truck is in position and the loading begins it is common for the truck bed to raise and lower due to the weight change. The back of the truck is tight to the face of the dock bumper; this up and down movement causes abrasion to the face of the dock bumper and puts stress on the dock bumper anchor bolts. A laminated dock bumper with a steel face absorbs the energy from the truck as it is backed into position. During the loading process the truck bed up and down movement now slides on the steel face of the bumper significantly removing the abrasion factor and also lowers the stress on the anchor bolts.
