HVR303 Electric Vehicle Restraint
32,000 lbs (14,545 kgs) restraining strength

The wall-mounted Blue Giant StrongArm™ HVR303 electric vehicle restraint secures a trailer to the loading dock via an electro-mechanical hook design.  Easy to install and eco-friendly, the HVR303 combines advanced engineering, positive holding ability, and sophisticated touch controls to make your loading dock safer than ever before.

Instant Compensation Float
With a vertical restraining range of 9" (227 mm) to 25" (635 mm) and instant float of 16" (406 mm), the HVR303 services a wide variety of trailers, including those with bent or damaged ICC bars. Ability to adjust automatically to trailer motion makes it compatible with air-ride suspension systems, enabling solid engagement and minimizing the risk of separation and worker injury.

Green Power
The StrongArm™ HVR303 is an environmentally sustainable alternative to oil-powered hydraulics. It can be interlocked with Blue Giant air-powered dock levelers to build a 'green' loading dock solution, allowing builders and developers to qualify for government incentives as well as project the image of an environmentally responsible business.

Strength You Can Depend On
With a restraining force of 32,000 lbs (14,545 kgs), the StrongArm™ HVR303 helps prevent the dangers associated with unexpected horizontal or vertical trailer movement. Secure gripping and holding capability enables a smooth and fortified bridge between the loading dock and the trailer, keeping cargo, equipment, and forklift operators safer during loading and unloading.
Designed to comply with ANSI MH30.3..

Interior and exterior LED lights keep drivers and warehouse personnel advised of safety conditions. A built-in network communication system enables multiple units of dock equipment to be operated in safe and proper sequence.
