The TPR UniLock® is the only trailer-postioned 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 vehicle restraint also has an internal safety mechanism that locks the restraint's hook in place when pressure is applied, maintaining a secure engagement. This makes it universally effective on any obstructed Rear Impact Guard (RIG), including intermodal trailers with cover plates that prevent the restraint's hook from latching on top of the RIG.
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 drive approach. The integral motor, gear and brake assembly is specifically designed for the UniLock. The UniLock vehicle restraint is highly adaptable to new or existing loading docks.
Hook rotates away from the trailer's Rear Impact Guard first, then down to a stored position, releasing RIG Wedge pressure without the trailer reversing.
Internal safety mechanism to lock the hook in place when force is applied from the trailer's RIG during loading/unloading, maintaining a secure engagement.
Maintains secure engagement on any obstructed rear impact guard, including intermodal trailers with cover plates.
Loading docks are noisy and horns may be missed. The McGuire advanced 3 light system has an amber caution light easily seen by the dock attendant warning a safe capture has not occurred so they can take appropriate steps to secure the trailer.
An exclusively designed integral gear motor, gear and brake assembly keeps the capture hook continuously engaged. Combine this with a low profile 9” carriage and a service range of 9” to 27” off grade and you have what you need in a vehicle restraint.
The Red/Green LED inside/outside lights and signs assure your dock attendant and the drivers are kept “in the know” for when it is safe to do any movement at the dock. We also incorporate an amber caution light in the event a safe capture has not occurred.
