Figure 5.15 Double-deep pallet racks at Storemax, London, England

a single pallet on hand to double-deep racking is nonsensical because one of the two positions in a facing is automatically wasted.) Because pallets are stored two deep, a double-reach forklift or reach truck is required for storage/retrieval (Figure 5.16). Drive-In/Through Racks Drive-in racks extend the reduction of aisle space begun with double-deep pallet racks by providing storage lanes from 5 to 10 loads deep and 3 to 5 loads high. Drive-in racks allow a reach truck or forklift to drive into the rack several pallet positions and store or retrieve a pallet. This is possible because the rack consists of upright columns that have horizontal rails to support pallets at a height above that of the forklift or reach truck. This construction permits multiple levels of pallet storage, each level being supported independently of the others (Figure 5.17).
