Transporting products move products, equipment, and materials from one place to another. Conveyors create a path for loads to move along. Casters install onto furniture and equipment to allow it to roll. Carts and trucks are wheeled vehicles with shelves or platforms that items are placed on so they can be moved more efficiently than would be possible if carrying them. Dollies and movers are wheeled devices that are positioned under large or heavy loads to reduce the physical effort it takes to move them. Forklifts are motor vehicles with fork attachments that allow very heavy loads to be loaded, moved, and unloaded.
