Intermodal Transportation & Its Impact On Vehicle Restraints

Rite-Hite is an example of a company that is developing universal vehicle restraints designed for both trailers and intermodal containers. The company – which invented the vehicle restraint industry in 1980 – continues to develop new products to meet industry demands.

Rite-Hite recently introduced the Dok-Lok® RHR-4000, which has a unique hook design that helps protect against all types of trailer separation accidents, accommodating traditional rear-impact guards and intermodal containers. In addition to having the most substantial wrap on rear-impact guards, the Dok-Lok RHR-4000 is the only product to incorporate the patented shadow hook, which adds another layer of safety by securing intermodal containers with rear-impact guard obstructions.

When the Dok-Lok is activated, the hook attempts to wrap around the rear-impact guard. If the hook comes in contact with a plate obstruction, the shadow hook pivots to secure the trailer in place. If the trailer moves, the shadow hook locks in the safety stop, which prevents trailer separation accidents.
