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.
- 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
- Good access to 50% stock locations
- Enables stock rotation
- Efficient in operation
- Relatively low cost racking system
- 40% increase in storage capacity
