Double deep pallet racking stores 2 pallets deep or 4 pallets deep between aisles. It delivers increased storage density when compared to wide aisle and requires special fork lift trucks.
Double deep racking simply has one row of standard pallet racking behind another. Using a deep reach lift truck, the operator places the back pallet into the system first, then places another pallet in front of it.
Selectivity is reduced by 30% over standard pallet rack, but 30% more pallets are stored for a given number of aisles. This increases productive use of floor space over a wide aisle system, offering the same sort of utilization as narrow aisle.
Double deep racking offers low initial cost, high productivity, and good selectivity. This double deep pallet racking system however, provides an excellent method of increasing warehouse capacity or when alternative systems are not possible.
Advantages of Double deep pallet racking:
- Higher capacity of up to 30% more than Selective pallet racking.
- Lower cost solution than Drive-In Racking, while increasing capacity by up to 30%.
- Redundancy rates can run between 10-20% dependent on the quality of the Warehouse Management System (WMS) program.
