MATERIAL HANDLING EQUIPMENTDisadv: Rack investment costs are greaterthan for double-deep racksMaximum depth is 5 loads6. Flow-through rackSimilar to push-back rack in terms ofstorage density, except greaterstorage depth is possible. Rack isloaded at higher end and unloaded atlower end, providing FIFO storagein each lane.Termed pallet-flow rack and cartonflowrack (pictured) when palletsand cartons used, respectively6(a) Carton-flow rackAdv: Allows a large cubic volume ofproduct to be accessible from asmall pick face area, supportingPallet Rack Carton Flow Rackrelatively high pick rates. Replenishment does not interfere with picking.Disadv: More expensive than bin shelving.Can have LED displays attached to shelf beam for “pick-to-light” operations (see Section Error!Reference source not found.)6(b) Pallet-flow rackAdv: Replenishment does not interfere with picking.Disadv: Requires twice as much aisle space as push-back racks, but overall storage density couldbe higher because of greater storage depth.Storage depth of 40 to 50 possible for pallet-flow racksReplenishPick Face58
