Dok-Lok RHR-4000 rotating hook restraint

Dok-Lok RHR-4000 Rotating Hook Restraint
Rite-Hite's Dok-Lok RHR-4000 Rotating Hook Restraint incorporates a patented shadow hook which adds another layer of protection against trailer separation accidents.

Rite-Hite’s Dok-Lok RHR-4000 Rotating Hook Restraint incorporates a patented shadow hook which adds another layer of protection against trailer separation accidents. In addition to having the most substantial wrap on rear-impact guards (RIG), the Dok-Lok RHR-4000 secures intermodal containers with RIG obstructions. 

The Dok-Lok RHR-4000 secures a semi-trailer or intermodal chassis to a loading dock by engaging the RIG with a patented shadow hook. The shadow hook features an innovative, rotating hook design that delivers the highest level of protection against trailer separation. When the Dok-Lok is activated, the hook attempts to wrap around the RIG. With an engagement range that extends from 9-inches to 30-inches above the ground, the hook reaches over 6-inches to help maintain engagement in below dock endload situations.

The powerful extension springs provide superior upward force against the RIG to keep the trailer secure during loading, even with air-ride trailers. If the hook comes in contact with a plate obstruction on an intermodal container, 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.
