Drive-In Rack is a high density type of Pallet Storage System that offers a limited amount of selectivity when it is compared to a Selective Rack System. Pallets are densely stored in bays by the fork lift actually driving into the rack structure several positions deep and high to store and retrieve pallet loads. This type of a System stores and retrieves pallets from the same aisle in a last-in, first-out order making Drive-In Rack ideally suited to operations that maintain a large quantity of a relatively low number of SKUs (stock keeping units). Normally, the same SKU and/or lot number is stored in the same bay because each level operates dependently of the other levels within the same bay.
Load rails are cantilevered out beyond the aisle frame to allow easier access into the Rack System. This option is also effective in minimizing fork lift abuse because the aisle frame is “set back” from the fork lift aisle. Flared and rounded load rails combined with reinforced columns and heavy-duty struts are an excellent abuse resistant design for an active System.
