Systems Loading Dock Equipment TPR UniLock Automatic Restraint

The TPR UniLock from Systems Loading Dock Equipment is a trailer-positioned vehicle restraint that can automatically remove rear impact guard (RIG) wedge pressure.

RIG wedge is caused when the trailer is pushed forward during loading/unloading by forklifts, and the trailer's 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.

Securely engages intermodal, obstructed RIGs

UniLock 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 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 pounds and has a service range of 4 to 10 inches horizontally from the face of the loading dock bumpers and 9 to 30 inches vertically above drive approach.

Adaptable to new or existing loading docks

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.

The TPR UniLock is available from Systems Loading Dock Equipment through its Poweramp, McGuire, and Dock Leveler Manufacturing (DLM) brands, installed with iDock controls.
