The CartCaddy4SC material handling cart has a variable speed thumb control for forward and reverse directions of 0-3 mph. The ergonomically correct variable speed feature prevents carpal tunnel and allows the operator to maintain smooth control while intricately maneuvering a heavy load. Most people go to hospitals to improve their health, but for hospital workers the danger of injury from potential ergonomic hazards is high. Healthcare workers risk musculoskeletal injury daily not only while handling a wheel cart, but during the performance of tasks in the work cell, storage room, maintenance and engineering areas of manufacturing and distribution facilities. DJProducts, Inc, specifically designed the CartCaddy4SC industrial electric cart for maneuvering carts with 4 swivel casters. The leg in the middle helps prevent fishing tailing of the cart. Their maneuverability has been maximized to accommodate both the tight spaces often found in manufacturing cells, materials handling situations, and the high pedestrian traffic typical in corridors.
