Vehicle Restraints

Vehicle Restraints hold truck trailers in place during the loading and unloading process – known as ‘trailer creep.’ Using a hook on the ICC bar of the trailer, these vehicle restraints prevent dangerous situations at dockside.
Available in both manual and automatic designs, these restraints make working on your trainload dock safer and faster. We also have communication light systems to let drivers and dock crew know when it’s safe after the load has been released.

Types of Vehicle Restraints

Automatic Loading Dock Truck Restraint
TRR Series Truck Restraint by DLM Dock Equipment

  • The TPR® is designed to withstand a pulling force in excess of 32,000 lbs, and has a service range of 4” to 10” horizontally from the face of the dock bumpers and 9” to 30” vertically above drive approach.

  • The integral motor, gear and brake assembly is specifically designed for the TPR®. The TPR® vehicle restraint is highly adaptable to new or existing loading docks.

  • *OPTIONAL* The TPR UniLock™ is the only trailer-positioned vehicle restraint that can automatically remove “RIG Wedge” pressure.

  • RIG Wedge is caused when the trailer is pushed forward during loading/unloading and the trailer’s Rear Impact Guard (RIG) applies so much pressure to the restraint’s hook that the truck driver must reverse the trailer in order to release the restraint.

  • The UniLock has an advanced cam design that first rotates the hook away from the RIG to remove the pressure, and then rotates down to a stored position.
