Advantages over drive-in racks include that there is no need to drive into the rack and there is no vertical honeycombing. Push-back racks are appropriate for medium- to fast-moving SKUs with 3 to 10 pallets on hand (Figures 5.22 and 5.23). Mobile Pallet Racks Mobile pallet racks (Figures 5.24 and 5.25) are essentially single-deep pallet racks on wheels or tracks permitting an entire row of racks to move away from adjacent rows.
