Live carton storage flow rack is a two-part gravity flow storage system consisting of wheeled flow rails set into a stationary rack structure. This allows the user to optimize warehouse space and provide better inventory control for perishable and time sensitive products in a FIFO environment. Live carton storage flow rack systems are entirely gravity fed, which reduce handling costs. The flow rails are set at an incline in the rack structure, allowing loads placed on one end of the rack to move down to the unloading end. Rollers let the loads move smoothly while self-energized speed controllers act as gentle brakes. As a load is removed, the loads behind it move forward automatically. Live carton storage flow rack systems allows users to increase product storage density with fewer aisles and forklifts.
