Gravity rollers are mainly used for transporters or conveyors. Largely metallic rollers are used to facilitate the handling and transfer of a large range of objects, such as boxes, floorboards, pallets, packages, etc. whenever these fulfil the condition of having a regular bottom. Should this not be case, other types of devices will be used such as belt conveyors, spiral conveyors, etc. The roller transporter is used in multiple industrial processes and in warehouses.
