New Rite-Hite Dok-Lok® Addresses Rise In Overseas Container Traffic

In response to the growing use of overseas (intermodal) shipping containers by the U.S. trucking industry, Rite-Hite has introduced the RHR-4000 Dok-Lok vehicle restraint. The RHR-4000 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 exclusive RHR-4000 also offers a water-and dust-resistant IP66 rated motor and a longer lasting, corrosive resistant finish that meets the ASTM B117 testing standard.

Rite-Hite created the vehicle restraint industry by introducing the original Dok-Lok in 1980. Like previous Dok-Loks that have been engineered to meet the logistical challenges of the time, the new RHR-4000 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. Always improving, the RHR-4000 “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.
“This product addresses safety and security issues that will only continue to grow as the percentage of intermodal trailers coming into U.S. distribution centers increases,” said Joe Manone, President of Rite-Hite Products. “The RHR-4000 offers the most universal hook design, with the best wrap on a RIG and the widest working range of any rotating hook restraint on the market.”

It is estimated that intermodal traffic is increasing at between 14.4 and 19.2% per year. Additionally, the U.S. Dept. of Transportation projects that international container traffic will more than double by 2020.

All Rite-Hite restraints come standard with the Rite-Vu Light Communication System, including Corner Vu (which provides immediate Dok-Lok status-at-a-glance to the forklift driver before entering the trailer) and Leveler-Vu (which confirms Dok-Lok status to the forklift driver while inside the trailer).

Rite-Hite is a world leader in the manufacture and sale of loading dock equipment, industrial doors, safety barriers and high-volume, low-speed (HVLS) industrial fans – all designed to improve safety, productivity, and energy consumption. Rite-Hite’s brand portfolio includes Rite-Hite Products, Rite-Hite Doors and Rite-Hite Fans, as well as Frommelt, Frommelt Safety and Zoneworks. The company’s continuing emphasis on research and development has led to a succession of new products that have pioneered their respective industry segments.
