TL85 Hydraulic Vehicle Restraint System


Prevent costly cargo and equipment damage, physical injury or worse easily with the patented TL-85 Truck Restraint System.

The TL-85 Truck Restraint provides superior restraining power to keep vehicles locked to the loading dock. Gone are the days of unsafe chocking.

The TL-85's unique hydraulic ’gate’ design swings up to confine the rear impact guard within the restraining area. Combined with the ability to service trucks with rear impact guard from 12” to 29” above ground and horizontal ranges of 0” to 12” beyond the face of the dock, the TL-85 accommodates the widest range of vehicles. Bent rear impact guards included.

Keeping maintenance to a minimum is everyone's objective, including ours. So the non-impact TL-85 is designed with only 3 moving parts. Adjustments are not necessary. And Zinc plating is applied to battle body corrosion in harsh climates.

The TL-85 continues to fight against mishap and mayhem on the other side of the drop-off zone with the TL-85 Communications Control Center. This combination of signal lights and controls advises both the truck driver and dock attendant of safe/unsafe, park/depart conditions. As an added feature, our TL-85 with remote power pack is an effective anti-theft device for unattended trailers.

Typical Product Application: Top-of-the-line, hydraulically powered vehicle restraint device designed to maximize employee safety by securing trailers to the loading dock and prohibit unscheduled departure during loading/unloading operations.

Type: Electro-hydraulic operated non-impact design. Driveway/wall mounted. Overall body dimensions not to exceed 13”W x 27”L x 17”H (330 x 686 x 432mm).

Vertical Restraining Range: From 12” to 29” (305mm to 737mm) above grade.

Horizontal Restraining Range: From 0” to 12” (305 mm) beyond the face of the dock.

Mounting System: Driveway and dock face mounting using 6 wedge anchor bolts ” dia. x 6” long (16 x 152mm). Transfer of pulling force to driveway improves restraining strength by equalizing forces on anchors. Trailer rear impact guard (ICC bar) during backing in does not impact restraint’s body.

Operating System: ½ hp, 115/1/60 TENV (Totally Enclosed Non-Ventilated) motor in remote location on 20” (6096mm) hydraulic hose, controlled from a NEMA12 rated remote control station with ”ON”, ”OFF” and key control.

Communication System: Interior red and green indicator lights in the control station. Exterior red and green high visibility traffic style lights and mirror image driver’s warning signs. The lighting system alerts both dock attendant and truck driver to the status of the restraint. If vehicle has no restraining ICC bar, the interior and exterior communications lights will flash red, warning the dock attendant that the vehicle is not secured and requires wheel chocks.

Rated Capacity: Welding procedure compliant with A.W.S.D1.1 98 specifications. Unit provides restraining strength up to 55,000lb (25,000kg) and mounting force of 75,000lb (34,000kg).


Construction & Finish:
Truck Restraint: Welded structural steel housing. Restraint arm is constructed of 1½” (38mm) thick solid steel and is of a non-impact design. The housing protects all components from damage from weather, dirt and debris. NEMA6 submersible rated switch, remote power pack location and cylinder vented to power pack reservoir protects from water damage. To resist corrosion and reduce maintenance, housing is zinc plated, main hinge pin is made of stainless steel and cylinder rod has nitrided coating.

Control Station: NEMA12 (oil and dust resistant) rated with key switch. Overall dimensions not to exceed 11½”W x 11½”L x 6”D (292 x 292 x 152mm).

Traffic Lights: The housing of each section shall be a one-piece molded ultraviolet and heat stabilized polycarbonate unit with protective tunnel visors. The lenses shall be 8-inch prism traffic signal types of red and green color. The overall body shall not exceed 11”W x 20½”L x 14”D (285 x 520 x 355mm).

Warranty: Standard five-year structural and one-year parts and labor from date of shipment. All warranties are subject to standard limitations on liability. Consult All-Rite for full details.
