The NOVA Truck Lock™ vehicle restraint keeps dock operations safe and secure during loading and unloading. Trucks and trailers are held firmly in place by a high-visibility barrier-style ram bar which can withstand a pullout force of over 30,000 pounds to prevent accidental separation from the loading dock during the cargo handling process.
The Flange Style housing is designed to be anchored into the concrete drive. This installation method provides years of trouble-free service without any damage to the building, unlike other restraints that attach to the dock wall. This style also allows for easier movement to other dock positions in the event of required location changes. It includes a completely self-contained, zinc-plated housing that can handle the harshest loading dock environments.

After the truck/trailer backs into position against the dock bumpers, the dock attendant switches the Truck Lock™ to the RESTRAIN position activating the restraint. The outside light turns red and inside light turns green, and after verifying the ram bar is above the RIG (Rear Impact Guard), the attendant may enter the trailer. When the attendant has completed the loading/unloading process, switch the Truck Lock™ to the RELEASE position deactivating the restraint and lowering the ram bar. The outside light turns green and inside light turns red.
The restraint is activated by turning a switch or moving a slide bar on the control console to the RESTRAIN position. The ram bar is raised by a high-strength, nylon-coated, aircraft-grade stainless steel cable and guided over heavy-duty pulleys with shielded bearings. The switch controls a pneumatic cylinder that actuates the cable and is located inside the building within a powder-coated steel enclosure. The mechanical version uses a slide bar located inside the building within a powder-coated steel enclosure to actuate the cable. Powered operations require air from a plant system or small compressor. Air must be dry and clean, and at a minimum of 80 psi and maximum of 130 psi. Air usage is approximately 0.015 cubic feet per operation. The duration of a normal power stroke is about two seconds.
The vertical ram bar is made from 4-5/16” wide by 1” thick ASTM A-514 Grade B plate with minimum yield strength of 100,000 psi. The housing is constructed from 6” x 3” x 1/4” ASTM A500 Grade B rectangular steel tubing, capped with a ram sheath cast of 55,000 psi minimum yield strength steel and fully welded to the housing tube. Half-inch thick gussets made from 36,000 psi minimum yield steel is welded to and reinforces the housing tube and ram sheath. The housing and gussets are welded to a 25” long x 16” wide (tapers to 9-/4” wide) x 3/8” thick base plate of 36,000 psi minimum yield strength steel. The housing is embedded into the approach with seven heavy-duty 5/8” x 5” long hex head anchor screws.
The control box comes with a factory-installed, 6-foot power cord. The drop cord can be plugged into any 120VAC 60Hz outlet and only draws 0.5 amps. All components are UL Listed® or Recognized® for industrial use. All LED lights (interior and exterior) operate on a 12V circuit. A qualified electrician is not required to install a Truck Lock™, as they are considered low voltage; however, always follow local ordinances and codes to determine actual site requirements.
