Blue Giant STRONGARM™ HVR303

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.


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.


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.


With a restraining force of 32,000 lb (14,545 kg), 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.
