Truck Restraint Overview

Also called truck locks. Most truck restraints mount onto the dock wall in the front and center position of the loading dock. It is a device that is designed to “hook” onto a trailers’ ICC bar  (Interstate Commerce Commission - regulates that all moderate and large trucks have a rear horizontal bar installed that is intended to prevent a vehicle from sliding under the trailer in a collision). Also called a RIG bar (Rear Impact Guard).  There are several different styles of truck restraints employing different types of “hooks”. Truck restraints use a set of green and red indicator lights located on the inside of a building  for the dock workers and another located outside for the truck driver. The purpose of a restraint is to prevent trailer creep (the trailer moves away from the dock) as the trailer is being loaded/unloaded and to prevent the truck driver from pulling away from the dock area during loading and unloading. Some manufacturers claim that their truck restraints will also prevent trailer upending in the event of the failure of a dropped trailers landing gear. Restraints can be ordered as mechanical, electric or hydraulic operation. They are an important safety feature that should be installed at every loading area. The cost can be prohibitive to some, but the benefits to employee and product safety is immeasurable. Serious injury or death can occur if the truck restraints are not in good working condition. It is very important to have regular safety checks on the inside and outside lights and safety signs between your regularly schedule preventative maintenance service. Proper maintenance and inspection is vital to having a safe and efficient working environment.
