Poweramp - Premium Loading Dock Systems MENU OUR COMPANY SHOP PARTS CONTACT USFIND A DEALER VIEW GALLERY 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 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. Now installed with Patent Pending PRODUCT DOCUMENTS REQUEST A QUOTE ADVANCED CAM DESIGN 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. UNIVERSALLY EFFECTIVE Maintains secure engagement on any obstructed rear impact guard, including intermodal trailers with cover plates.
