Used for movement of materials, products and loads throughout a manufacturing or distribution facility. Conveyors are horizontal, inclined or vertical devices and are powered by gravity, hydraulic or electrical feed. Totes, trays or pallets travel via belt, rollers, chain or other material along a fixed path with specific points for loading and discharge. Conveyors allow large volumes of material to be moved rapidly through a process or facility; conveyors reduce labor costs by eliminating non-value-added travel time. Typical conveyor applications include movement of cases, totes or palletized loads into and out of a trailer, to and from static or automated storage systems, or from a picking area to packaging for shipping.
