Why Your Loading Dock Should Have a Vehicle Restraint

June 9, 2020

No matter if you run a shipping company or you regularly send or receive cargo at your business, it’s crucial to maintain best safety practices with the trucks docked at your warehouse or facility. One of the most important things you can do is install quality vehicle restraints at each of your loading docks. Here’s a brief overview of these essential pieces of safety equipment and why they’re necessary.

How Vehicle Restraints Work

A vehicle restraint holds a truck or other automobile in place while it’s parked, but there are two different main designs. While both models perform the same purpose, the manner in which they accomplish this task varies:


The Shadow Hook Dok-Lok is a universal locking system that alleviates the intermodal compatibility problems that sets them apart from standard rotating hook locks. This feature helps prevent all types of trailer separation accidents on all types of trailers. 

The Wheel-Lok restrains virtually all trailer types with maximum reliability. The wheel guides properly position the trailer, which protects the building and ensures a secure dock seal. Both products will safely secure trucks in your loading dock, but you should make sure you’re installing the right model for your business.

Common Issues Vehicle Restraints Can Solve

  • Trailer Creep

Wheels are an essential component of any automobile but can create a hazardous situation at loading docks. If you use forklifts to move cargo, the repeated forward motion of the lift driving into the truck can cause it to slowly pull away from the dock, known as trailer creep. When enough movement occurs, it can create a dangerous situation that could lead to an accident. Wheel chocks are traditionally used to prevent creep from happening, but they aren’t nearly as reliable as a restraint system.

  • Landing Gear Failure

When a trailer is attached to a truck, it remains relatively stable, but it’s not always feasible to keep trucks attached during extended periods of time. When separated, trailers rely on a stand known as a landing gear to keep it from tipping over. If a landing gear collapse occurs during loading, the entire trailer could tip forward and cause injuries as well as damage to equipment. A hooked restraint system holds the trailer’s back end in place and can be strong enough to keep things upright if a collapse occurs.
