Casters with high load capacities exceeding 850 lbs are designed for the heaviest workloads. With strong wheels made of Ergolastomer, MaxRok, or ductile steel, these casters can handle the toughest load-bearing tasks with ease. The 3" wide treads, available for extra heavy-duty applications, provide a safe and secure way to mobilize even the heaviest equipment. These casters are particularly useful for large dumpsters, hoppers, and other equipment that require reliable and robust casters or replacement wheels. If you need to move bulky and heavy equipment with ease, high-capacity casters are an excellent investment.
