Checkers’™ wheel chocks were engineered in collaboration with safety experts to work with a wide range of ground equipment, commercial, and military vehicles. Whether you are chocking a fully-loaded 400-ton haul truck or a small utility trailer, we have the wheel chocks you need to safely secure your vehicle and meet compliance standards.
Our chocks have been field-tested under various conditions to ensure they prevent non-motorized, uncontrolled movement of on and off-road vehicles. Checkers™ has also worked with a third-party laboratory to certify that each model meets the specifications indicated on the Checkers™ Wheel Chock Reference Guide. Specific models of our Checkers™ wheel chocks meet specifications required by MSHA (Mine Safety and Health Administration), OSHA (Occupational Safety and Health Administration), SAE (Society of Automotive Engineers), NFPA (National Fire Protection Agency), and the DOT (Department of Transportation).
Aviation wheel chocks secure both commercial and private aircraft. The AC series wheel chocks are made of highly durable, lightweight polyurethane. AC chocks last longer than wood chocks, never need painting and eliminate Foreign Object Damage (FOD) threats for aircraft.
General-Purpose wheel chocks are comprised of two lines, the UC and RC series:
- The UC series wheel chocks are manufactured with highly durable, lightweight polyurethane. These chocks are ideal for use with over-the-road trucks, trailers, pickups and utility vehicles. For tire diameters 27 in. to 65 in. (68.6 cm to 116.8 cm).
- The general-purpose RC series wheel chocks are composed of durable rubber that makes them strong and safe in industrial applications. The RC models are resistant to damage from UV, moisture, salt, and oils. Their traction design grips the tire and road and will not cause tire or pavement damage. The chock design also allows either side to be positioned against the tire. This series of chocks is built to suit a variety of applications in the construction, utility, and other commercial industries.
Heavy-Duty wheel chocks (MC series) are manufactured with highly durable, lightweight polyurethane construction. Ideal for use with heavy equipment such as haul trucks, loaders, and cranes. For vehicles with wheels with a diameter of up to 165 inches. MC chocks are the #1 selling wheels chocks in the mining industry, approved and used by Caterpillar and mines worldwide, made of tough, weather-resistant urethane, resistant to oils, fuels, and solvents, and meet MSHA specifications.
