Vehicle restraints help prevent serious accidents during loading and unloading operations. They stabilize the vehicle and prevent any unexpected movement that could endanger your employees. By securing the connection between the truck and the dock, these systems ensure smooth, risk-free productivity.
Vertical barriers
Our vertical barriers provide robust protection against accidental trailer separation. This equipment reduces accident risks caused by unexpected trailer departures and the costs associated with work stoppages. This force effectively stabilizes the vehicle, preventing premature departure or gradual truck movement.
We offer three Rite-Hite models tailored to your specific needs:
- The VBR-100 is a reliable wall-mounted solution that is easy to install.
- The VBR-300 is installed directly on the ground with a reverse-bevel design for increased protection. This unique shape ensures maximum grip on the vehicle’s safety bar.
- The VBR-600 is recessed below the pit for total discretion and formidable efficiency.
This equipment is designed to last and withstand the most demanding conditions.

Rotating hooks
Rotating hooks represent the most advanced technology currently available for trailer restraint. Their unique design allows them to firmly grip the vehicle chassis through a precise rotational movement.
The SHR-5000 model stands out with its “Shadow Hook” technology. This system can secure even the most complex multimodal container chassis.
Meanwhile, the GRH-700 focuses on exceptional simplicity for minimal maintenance and consistent reliability.
For companies seeking total stability, the STR-4200 is the ideal solution. It drastically reduces vertical and horizontal movement during forklift operation. This stability not only improves safety, but also extends the service life of your dock equipment.

Wheel chock restraint systems
Certain truck configurations do not allow the use of a traditional hook on the underride guard. This is the case for trailers with hydraulic liftgates or low-profile chassis. For these situations, we offer the Wheel-Lok™ range, which acts directly on the vehicle’s wheels.
The GWL-2300 model is fully automatic and uses the truck’s own energy to lock the rear wheels. This wheel-locking restraint system adapts to nearly all tire sizes for exceptional versatility.
If you prefer more direct control, the MWL-1300 is a highly effective manual option. This device is easy to operate and guarantees perfect immobilization for a wide variety of fleets. It is the ideal alternative to secure every dock position, regardless of truck type.

The communication and control system
Effective restraint equipment must be accompanied by clear communication between drivers and staff.
The Dok-Commander® intelligent control box centralizes the management of all your safety devices at each door. It allows equipment interlocking to ensure devices are used in the correct sequence. This virtually eliminates the risk of human error during operations.
In addition, the Rite-Vu™ light communication system provides total visibility of safety status. Visual signals such as Pedestrian-Vu warn staff when a forklift is operating inside a trailer. Outside, Approach-Vu uses audible and visual sensors to protect pedestrians from approaching trucks. This perfect coordination creates a highly secure and reassuring work environment for your teams.

FAQ
Are vehicle restraints mandatory in Quebec?
Although not explicitly mandatory, the CNESST requires technical measures to restrain trailers during transfer operations. Employers must prevent unexpected departures. Vehicle restraints directly meet these regulatory requirements.
What is the difference between a vertical barrier and a rotating hook?
Vertical barriers apply pressure to the underride guard. Rotating hooks grip the vehicle chassis directly. The choice depends on your trailer types and dock configuration.
Is the Wheel-Lok system suitable for all trucks?
Yes. Wheel-Lok locks the rear wheels directly and adapts to nearly all tire sizes. It is the ideal solution for trailers with liftgates or low-profile chassis.
Is the Dok-Commander system mandatory?
No, but it is strongly recommended. This intelligent control box centralizes device management, interlocks equipment, and eliminates human error. It significantly improves overall operational safety.
Do these systems require regular maintenance?
Yes. Preventive maintenance ensures proper operation of your restraint systems. Canado-Nacan provides technical support and inspection programs to ensure the ongoing reliability of your Rite-Hite equipment.
