What are the most common loading dock product electrical interlocks?

Although there are many combinations available there are 2 very common interlocks specified. 1. Interlocking a vehicle restraint to a hydraulic or air powered dock leveler. This interlock is safety related, the dock leveler will not operate until the truck in position has been secured by the vehicle restraint. The truck secured signal from the vehicle restraint now renders the dock leveler controls operational. 2. Interlocking the overhead door to a hydraulic or air powered dock leveler. This interlock is used to reduce potential damage to the overhead door and improve building security. Before the dock leveler will operate the overhead door must be raised which activates a wall installed limit switch. The activated limit switch now renders the dock leveler controls operational. When the dock leveler is cycled it will not contact the overhead door causing damage to the door and the locking mechanism.

Why are there more and more steel face loading dock bumper in use?

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.
