Also known as "POWER CHOCK^®" literally means "chock strength". The POWERCHOCK^® is a wheel locking system, composed of a steel chock and a retaining plate fixed to the ground, which retains all types of vehicles at the loading docks by blocking a rear wheel.

To know all the advantages and benefits of the POWERCHOCK^® system, please check the "YOUR WARRANTY & BENEFITS" page. Details on existing models are available on the POWERCHOCK^® 3 and POWERCHOCK^® 5 product pages.

The POWERCHOCK^® line of products offers different models to meet the needs, expectations and constraints of our customers. This comparison chart provides a good overview of the characteristics of each of these systems, but our team is of course at your disposal to answer your questions.

Yes, we have designed effective restraint devices to secure all vehicles arriving at the transshipment docks to perform loading and unloading operations: - Semi-trailers - Trucks - Swap bodies

A locking arm (or blocking arm) is a ground system equipped with a metal bar which deploys sideways to be placed in front of the rear wheel of the truck which has just docked at the loading dock. The holding force of some commercially available locking arms is approximately 14 tons. The hook system hooks the impact bar, also called underrun bar, ICC1 or RIG2 bar, to the rear of the truck. By gripping this bar, this device aims to retain the semi-trailer. The problem arises when the vehicle is not or no longer equipped with an ICC bar, or when it is in poor condition - which is the case for one in four vehicles. In addition, the hook itself can damage the underrun bar (or guard). Finally, the holding force of some models of hooks for sale is about 15 tons. As the name suggests, the POWERCHOCK^® wheel blocker is a frontal securing system with a galvanized steel chock placed in front of one of the rear wheels of the truck - and simultaneously on the plate fixed to the ground - to block the wheel in question and therefore the vehicle in the event of an untimely or unexpected departure. The holding force of the POWERCHOCK^® blocking solution is 25 tons.

All POWERCHOCK^® models are manufactured in our factory in Canada to the highest quality standards in the industry. Built to last, many of our customers have warehouses with docks that have been equipped with the same POWERCHOCK^® systems for 15 years.
