TPR UniLock® Automatic Restraint
Loading Dock Truck Restraint
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.
The UniLock 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 the drive approach. The integral motor, gear, and brake assembly are specifically designed for the UniLock. The UniLock vehicle restraint is highly adaptable to new or existing loading docks.
