With very high utility of storage space, pallets stored on inclined gravity rollers from input side to output side, thus following FIRST IN, FIRST OUT principle, particularly suitable for goods having few SKU’s and time limit of storage. This kind of racking is normally serviced by forklift and fork trucks. Fork trucks never enter the rack. Picking and Replenishment sides are separate. Pallets are fed in from one side, and retrieved from the opposite side eliminating double handling from the receiving area. Speed of throughput combined with automatic stock rotation is the major advantage of this system.
