The RHR-4000 Dok-Lok vehicle restraint meets demand for the growing use of overseas (intermodal) shipping containers by the U.S. trucking industry. The rotating hook restraint adds another layer of safety by securing overseas container chassis, which can have a plate or obstruction above the rear impact guard, while maintaining its exclusive hook design that provides the largest wrap over rear impact guards in the industry. The unit also offers a water-and dust-resistant IP66 rated motor and a longer lasting, corrosive resistant finish that meets the ASTM B117 testing standard. The unit helps prevent all types of trailer separation accidents, including early departure and landing gear collapse as well as trailer creep, pop up, upending and tip-over. The “shadow hook” adds an additional layer of safety to secure container chassis or rear impact guards (RIG) with obstructions. Dok-Lok rotating hook restraints are also designed for impact and to withstand today’s increasingly frenetic loading dock environment, with an enhanced track for better performance.
