Double Deep Pallet Racking

Double Deep pallet storage is a simple adaptation of placing one row of 100% selective rack behind another. Using a deep reach lift truck, the operator places the back pallet into the system first, and then places another pallet in front of it. While selectivity has been reduced by one-half over standard pallet rack, twice as many pallets are stored for a given number of aisles. This increases productive use of floor space about 60% to 65%.

Double deep storage rack has become a very popular choice in "high throughput" operations. It offers low initial cost, high productivity, good selectivity and less equipment damage However, the disadvantage include the need to have double reach trucks, loss of absolute FIFO and poor visibility for the truck driver when accessing the rear location.
