Proven Performance: Designed to meet specific wheel geometries, the MC4011 ensures positive holding power on vehicles weighing up to 1,600,000 lbs (800 tons) and tire sizes up to 165 inches (419.1 cm) in diameter. It has been rigorously tested on uphill and downhill grades.
Manufactured in the USA, Checkers new ultra-class wheel chock meets MSHA specifications and is constructed from weather-resistant HDPE, which also makes it resistant to oils, fuels, and solvents typically found in mining environments.
