Together, the wheels have a load capacity of 2, 400 lb. and weigh 28 lb. This product is intended for use in professional and industrial environments. Dollies are used to transport any of a variety of large, heavy objects, such as cabinets, crates, drum containers, furniture, heavy machinery, large appliances, rolls of carpet, or totes. Dollies are typically comprised of a low platform or deck mounted to caster wheels that may swivel for maneuverability and may include brakes to keep the dolly from rolling. Some dollies have adjustable frames to transport loads of different sizes. Others come with a pull handle to help the user move the dolly. Dollies can be used by professional movers or in warehouses or other industrial environments. Vestil manufactures materials handling equipment, including hoists and trolleys, jib and gantry cranes, loading dock equipment, and storage solutions.
