Double Deep Rack1

Double Deep Pallet Racking is probably the best compromise between a selective and non-selective pallet racking system. Using economical components in a double-deep, double-sided configuration, density and selectivity are achieved. 

Double Deep Pallet Racking is used in conjunction with special forklifts, often fitted with a pantograph mechanism, specially designed to reach the second pallet location.

Storing pallets two-deep for better capacity

  • Double deep racking stores two pallets deep in a single entry rack or four pallets deep in a double entry rack.
  • This system requires the use of a special reach fork lift truck with either dual pantograph or sliding fork attachments.
  • Double deep racking improves storage density with fewer aisles and more storage locations. This reduces the aisle to rack ratio but also reduces selectivity (FIFO).
  • Truck lift heights are limited by load, to about 9 metres.
  • The upper levels can be fitted with front to back guide rails to assist the operator to locate and place a pallet at height. The bottom beam must be sufficiently clear of the ground to allow the reach trucks legs to pass under it.

Features 

  • Storage density increased as rack aisle ratio changes from selective racking.
  • 50% immediate accessibility with reasonable stock rotation.
  • Good use of all available locations, typically 90%.
  • Safe and secure handling with the bottom pallet usually off the ground.
  • Ability to use double deep handling equipment for other tasks.
  • Best used when each SKU has several pallets.

  • Greater use of available headroom
