Dock Locks & Vehicle Restraints
Dock locks and vehicle restraints are crucial safety devices designed to secure trucks and trailers during loading and unloading operations at docks. They provide a reliable means of preventing accidental vehicle separation, reducing the risk of accidents and injuries. Dock locks and vehicle restraints typically consist of heavy-duty components that securely engage with a truck's rear impact guard or ICC bar to effectively immobilize the vehicle. They are commonly used in logistics facilities, warehouses, and distribution centers.
