SHR-5000 Shadow Hook® Restraint

Helps secure intermodal containers or trailers with RIG obstructions  
Widest working range (9”-30”) for consistent RIG/ICC bar contact 
Dual clad track provides 50% more track strength to help minimize damage


  • Exclusive Hook Design – Exclusive Hook Design offers more wrap than any other restraint which helps maintain engagement in below-dock end load situations. Contoured Hook is designed to entrap RIG equipped trailers (mandated in 1998) as well as outdated ICC bars. Shadow Hook technology allows restraints to properly engage intermodal chassis and obstructed RIGs.  
  • Widest Working Range – SHR-5000 has a 9” – 30” working range for consistent RIG and ICC bar contact while the spring-loaded structural hardened steel housing is automatically positioned when the unit is contacted by a backing trailer.
  • Reliable Performance – Dual clad track provides 50% more track strength to help minimize damage for heavy loading environments or aggressive pull-out attempts on SHR-5000. Standard on 9” carriages, the dual articulating nose extension ensures the widest range of coverage to help protect the SHR-5000 from potential damage when servicing RIGs lower than 22”.  
  • Integrity of Installation – Completed dock survey required for each dock position to help ensure safe and proper application of all Dok-Loks. Critical to the safety of material handlers and equipment, the surveys are reviewed by expert Applications team if outside of standard dock configuration.
  • Pull-Out Force Benchmarks – Rite-Hite was the first loading dock equipment manufacturer to establish pull-out force benchmarks based on years of research and development. Followed today by many other manufacturers, all Rite-Hite restraints are installed with mounting force in excess of 100,000 lbs. and 32,000 lbs. of pull-out force, doubling what tractors can achieve when in first gear.
  • Withstand Harsh Loading Dock Environment – Military grade corrosion resistant finish on rotating hook track, base plate, and housing. Mounted above ground away from dirt, debris, snow, ice and standing water, SHR-5000 successfully endures 1000 hours of salt spray testing compared to only 100 hours of galvanized restraints. Flood seal option seals IP-66 rated motor to help protect against decline dock flooding in case of heavy rain fall, drainage system failures and more.
  • Non-adjustable Safety – SHR-5000 is equipped with a non-adjustable motor clutch, individually set at the factory to help ensure that safety is never compromised in the field because a setting is “out of adjustment.” 
  • Auto-refire technology – SHR-5000 Lok will re-engage with RIG upon movement to ensure optimal and consistent engagement, helping to protect material handlers, equipment and product.  
  • Communication and Control – Dok-Lok® Style Light Communication communicates via interior lights when trailer is properly engaged, thus safe for material handlers to enter. Approach-Vu™ visual and audible warning for pedestrians is available as standalone or embedded in the housing of the SHR-5000. The system is activated by the presence of a backing vehicle in the drive approach, indicating the need for pedestrians to safely vacate due to a looming threat.
  • Help Prevent Trailer Separation Accidents – SHR-5000 helps to prevent early departure, trailer creep, landing gear collapse, trailer pop-up and up-ending.
  • Certified to meet and exceed ANSI MH30.3 performance testing standards.

Rite-Hite Communication and Control allows facilities to:

  • Integrate additional/future equipment and interlocked sequence of operations with Dok-Lok® Style Light Communication System.
  • Incorporate line of sight light communication system status with Corner-Vu™ and Leveler-Vu™.
  • Extend Blue Light Policy to help prevent 80,000 annual forklift-pedestrian accidents by extending reaction time with Pedestrian-Vu™.
  • Help prevent 2nd leading cause of backover fatalities in the United States with Approach-Vu™, which utilizes a light and horn system to present a clear visual and audible warning to pedestrians in the drive approach when a backing vehicle is detected.
  • Verify Dok-Lok engagement and trailer stand presence via outside camera and inside monitor with Lok-Vu™, reducing the amount of processes on the dangerous drive approach.
  • Integrate multiple loading dock control components at each dock position for a total dock safety system with Dok-Commander® Combined Controls.

All components are available as standalone or incorporated with Dok-Lok Style Light Communication System. The Dok-Lok Style Light Communication System offers more flexibility, facilitating the greatest long-term yield per dock position. The system allows facilities to address their most urgent safety needs first but reserving the opportunity to integrate vehicle restraints and other safety solutions at a fraction of the cost compared to standalone equipment purchases.
