The Patent Pending NOVA Lock & Load™ Vehicle Restraint with Roller Slope Extension is designed to secure a trailer to a loading dock by engaging the trailer’s Rear Impact Guard (RIG) with a large, rotating hook operated by a control panel mounted inside the building. The Roller Slope Extension is designed to decrease resistance of carriage travel while it is adjusting to the height of the RIG on the trailer thereby saving wear on the RIG, carriage and pavement. Engagement range extends from 9–30 inches (229 mm to 762 mm) above the ground. A spring-loaded, structural steel housing automatically positions the unit when contacted by a backing truck.

Mounts to dock above ground level to stay clear of accumulated precipitation and debris. Protected from the elements with watertight connectors and zinc plating, which provides exceptional corrosion resistance.

Features and Benefits

  • The gear motor, specifically engineered for this application, utilizes a one way braking system which keeps the hook continuously engaged for added safety
  • Roller slope extension that effortlessly rolls on pavement
  • Control box has standard horn override feature for authorized personnel
  • LED lights are standard for energy efficiency and long life

As the trailer backs into position, the RIG contacts the spring loaded structural steel housing which rides down in its track, allowing the RIG to move over the top of the housing. The dock attendant pushes the RESTRAIN button which activates the hook to secure the trailer to the dock that can withstand a pullout force in excess of 38,000 pounds. The Lock & Load™ restraint maintains contact with the RIG and adjusts automatically with trailer float motion to ensure proper engagement at all times. After servicing is complete, the dock attendant pushes the RELEASE button. In the event a trailer’s RIG is missing or damaged, the Lock & Load™ will communicate a fault condition. An audible alarm and flashing red light alerts the operator that the trailer has not been properly secured. The operator may secure the trailer by other means then override the fault condition. The communication system automatically adjusts to reflect the current operational mode.
