R&B offers a great safety option with our spring dollies. All poly and bushel trucks can be equipped with our ergonomically designed, safety oriented spring dollies to prevent back injuries by minimizing reaching and bending. The heavy duty 3/8 inch wire frame is covered with fire retardant vinyl/nylon laminate material to offer a durable and attractive product. The dolly that is specifically designed for each truck will allow the load to be moved higher as weight or capacity is reduced making it a great safety option. Each spring dolly comes with four zinc plated hooks specially designed for each style of truck with matching color vinyl/nylon protective sleeves to prevent the potential for pinching as the springs expand and contract. This is a great product that will save wear and tear on your employees. Spring lifts and protective sleeves are in gray for all poly trucks. Color: Gray. Size: 36 inches long x 23 inches wide.
