This Checkers heavy-duty wheel chock handles the biggest equipment on your site. Built from high-density polyethylene, it's rated for vehicles up to 550,000 lbs gross operating weight and tire diameters up to 105 inches. The 275-ton capacity makes it suitable for mine haul trucks, large loaders, and heavy cranes where standard chocks won't cut it.
The chock features replaceable rubber anti-slip pads and a recessed carrying handle on the back. Safety yellow color meets ANSI guidelines, and molded-in instructions show proper placement in English. It's resistant to oils, fuels, and solvents that are common around heavy equipment. The unit meets MSHA specifications and includes a mounting hole for securing with ropes or chains. Optional studs are available for snow and ice conditions.
Caterpillar and mines worldwide use these chocks for their heavy fleet operations. The larger base design provides stability for equipment where vehicle safety is critical. A barcode on the back helps with inventory tracking across multiple job sites or equipment yards.
