The Essentials: Drive-In Pallet Rack
Whereas traditional selective pallet rack consists of upright frames, cross beams and wire decking, drive-in pallet rack is made up of upright frames and horizontal rails upon which pallets can sit. These rails are oriented depth-wise in the rack system, and are situated at both sides of a pallet rack lane. This allows forklifts to completely enter the pallet rack system. In a selective rack system, this would be prevented by the presence of cross beams. This, in turn, makes for very high storage density, or the amount of product in a given space. This is considered a positive attribute, as it makes for a more efficient use of space. However, because product is loaded and unloaded from the same side of the rack system, drive-in pallet rack operates with first in, last out (FILO) inventory retrieval. This means that the products stored within a given pallet rack lane should be like-product, and should not be sensitive, as one would have to move several of the front pallets out of the way to access one of the rear pallets. Also, attention must be paid to drive-in rack maintenance, as driving into the rack system increases danger for the forklift operator and can increase the possibility of damaging the rack.
