Over/Unders are heavy duty chain and roller conveyor systems for staging and presenting large steel racks for pick and pack operations.
Over/Unders are automated floor mounted powered conveyor systems designed to move large and heavy racks. They feature all steel construction, heavy-duty components and controls based safety interlocks. Over/Unders use a vertical lift and feature a return lane above or below the feed lane.
Over/Unders streamline material handling in a plant and provide cost savings by reducing forklift and operator idle time. Each lane of a rack transfer can store several racks allowing a forklift to load or unload multiple racks at one time.
The return lane of an over/under is above the feed lane. This reduces the footprint of the equipment saving valuable floor space.
Over/Unders are popular in automotive assembly plants, as they utilize a large number of racks for each subassembly and take up less floor space than conventional side-by-side rack transfers.
