Palletised Storage: Double Deep Pallet Racking

The Double Deep Pallet Racking is constructed to store 2 pallets deep or 4 pallets deep in double entry rack, used ideally when multiple pallet quantities of each product are stored.

A derivative to the selective pallet racking, the double deep system requires the use of a specialist reach truck or an attachment fitted to reach truck. Whilst achieving increases in capacity of up to 30% above the former, only 50% of the pallets are immediately accessible.

This system, however, provides an excellent method of increasing warehouse capacity or when alternative systems, such as the Drive-in Racking, which require high numbers of homogenous pallet types, are not possible.

The advantages of Double Deep Pallet Racking are:
  • Increased storage density; and
  • Highly spaced-efficient storage system.

The disadvantages of Double Deep Pallet Racking are:

  • Requires specialised forklifts like the double reach trucks;
  • Speed of access to all of the pallet positions is restricted;
  • Loss of absolute FIFO; and
  • Poor visibility for the truck drivers when accessing the rear locations.
