Hydraulic Truck Restraints — Positive Trailer Engagement for Safe Loading
Truck restraints prevent trailer creep and unexpected departure during loading dock operations — one of the most common causes of serious dock injuries. Hydraulic truck restraints provide automatic, positive engagement with the trailer’s ICC bar, removing the risk of manual restraint failure. Wilcox installs and services hydraulic restraint systems for high-volume docks across Canada.
Dock Safety That Doesn't Rely on Human Memory.
Wilcox hydraulic restraint installations include proper anchor positioning, control panel integration, and full safety interlock testing with your dock leveler and door systems. We install and service all major brands and can integrate restraint systems with traffic light communication systems for additional driver awareness. Documentation provided for safety compliance records.

Hydraulic Truck Restraints vs. Mechanical Truck Restraints
Feature | Hydraulic Truck Restraints | Mechanical Truck Restraints |
Activation | Push-button automation | Manual operation |
Safety Features | Auto-adjusting, constant hold | Spring-based locking mechanism |
Maintenance Requirements | Low – sealed hydraulic system | Regular maintenance required |
Load Capacity | High – handles heavy loads | Limited by mechanical strength |
Best Use Cases | High-volume industrial use | Moderate-volume dock operations |
Hydraulic truck restraints provide hands-free automation, increased safety, and durability, making them the preferred choice for modern loading docks.

Frequently Asked Questions
A truck restraint locks the trailer to the dock to prevent trailer creep or early departure during loading. Without one, trailers can shift — a leading cause of dock accidents. Ontario workplace safety regulations and OSHA increasingly require active restraint systems.
Hydraulic restraints engage automatically and integrate with dock light systems to control forklift access. Hook restraints are manual — reliable and cost-effective for lower-volume docks. Wilcox recommends hydraulic for high-cycle operations.
Most ICC-compliant trailers work with standard hook and hydraulic restraints. Specialty trailers (flatbeds, tankers, low-boys) may require alternate restraint configurations. Tell us your trailer mix during consultation.
Annual service: mechanism function test, hydraulic check (if applicable), safety light test, and mounting hardware inspection. In harsh environments (salt exposure, freeze-thaw), inspect more frequently.
Wilcox stocks common restraint parts on service vehicles for same-day repairs. Our emergency line is 1-800-528-4131 — 24/7 response for any dock safety equipment failure.
