Pallet/Gravity Flow Rack

Pallet flow rack, also known as gravity flow rack, is a dynamic storage system that utilizes inclined rollers or wheels to facilitate the movement of pallets from the loading end to the unloading end. It operates on a First-In, First-Out (FIFO) basis, allowing for efficient stock rotation. Lane configurations are typically designed with multiple lanes to accommodate different products or SKUs.

Flow rack for pallet storage consists of selective rack integrated with gravity flow rails, or rollers. Flow rails decline from the loading side of the pallet rack to the unloading side of the pallet rack. Pallets move along the inclined lanes under the force of gravity, ensuring automatic flow toward the picking end. The pitch can be changed to provide a gentile flow that will not damage the product. Flow rails, or rollers, guide and support the pallets as they move through the system. As one load is removed from the unloading side of the pallet flow rack, the next load flows down into the unloading position. With the addition of a gravity flow speed controller, the speed of the pallet as it moves down the flow rails can be controlled.

More complex systems, such as Pick Modules, can flow pallets automatically to a carton flow system so pallets can be broken down for split-case picking.
