Heavy duty castors are designed to withstand heavy loads. Whether a large warehouse needs to move bulky items from floor to floor or a small home, a heavy duty caster must be durable enough to carry the weight. Different types of heavy duty castors have different capabilities. Some are built for rougher terrain, while others are designed for smoother surfaces.
Where should caster wheels be placed?
Heavy duty castors are fabricated from thick steel plate and are made to withstand high loads and shock forces. The forks of these castors are welded, rather than pressed. They are also zinc-plated for corrosion resistance. Many heavy duty castors can be customized to meet specific specifications, based on their intended use.
Heavy duty casters are available in rigid and swivel designs. Swivel castors can rotate 360 degrees while rigid casters can only roll forward or backward. They are most often used in medical equipment and attach to equipment via a stem. The materials used for heavy duty casters include polyurethane, nylon, stainless steel, and cast iron.
Heavy duty casters are generally larger than standard 4″ caster wheels. They also have a higher load capacity. Some casters can carry as much as a small car. On the other hand, medium-duty 4″ casters are limited to about 300 pounds and are usually found on file cabinets and office chairs.
