Panel, bar, pipe, and bucket trucks are wheeled carts or racks used for storing and transporting long, heavy, large, or bulky materials. Panel trucks have a vertical or sloped frame that supports long, thin panels or sheets such as drywall, plywood, glass panels, and partitions. Bar and pipe trucks have arms, cradles, or other features that keep pipe, bar stock, channels, and other long items from rolling off the trucks. Bucket trucks minimize the effort it takes to lift and move heavy 5-gal. buckets filled with paint, joint compound, industrial lubricants, dry goods, and other materials. Panel, bar, pipe, and bucket trucks are used in construction sites, manufacturing plants, facility maintenance shops, warehouses, and other industrial locations.
