Handling wheel block MC4011

polyurethane

The Checkers MC4011 Ultra-Class Wheel Chock is engineered for ultra-class mining vehicles, providing exceptional safety, ergonomic handling, and long-lasting durability. It is specifically designed to secure the largest haul trucks in the mining industry, supporting vehicles weighing up to 1,600,000 lbs (800 tons) and tire sizes up to 419 cm (165 inches) in diameter. This wheel chock complies with MSHA and OSHA regulations, ensuring peace of mind in high-risk mining environments. Its high-visibility yellow color enhances safety in low-light conditions, while the lightweight, compact design (less than 30 lbs, 24% lighter than industry standards) meets NIOSH one-person lift requirements and reduces operator fatigue. The ergonomic handle and compact size allow for easy transport and positioning, and the chock can be used with or without mounting brackets, making it suitable for inclines and uneven terrain. Constructed from high-density polyethylene (HDPE) and UV-stabilized polyurethane, the MC4011 is resistant to oils, fuels, solvents, and extreme weather conditions, with replaceable anti-slip pads for added safety. Its innovative design ensures compatibility with specific wheel geometries for maximum holding power under extreme loads, improving operational efficiency and compliance. The MC4011 is the ultimate choice for securing heavy mining vehicles, enhancing ROI and operational safety.
