A derivative to the selective pallet racking, the double deep system requires the use of a specialist 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 Drive-In which require high number of homogeneous pallet types, are not possible.
Facts about double deep racking
- Lower beam level required for some types of equipment
- Operates up to height of 10m
- Average stock rotation
- Average order picking, 50% selectivity
- Average Floor area utilization
- 40% net pallet area usage of overall warehouse area
- Redundancy rates can run between 10-20% dependent on the quality of the WMS programme
- Popular against Drive in Racking, as a lower cost alternative which increase capacity over selective by up to 30%
- Recommend the use of pallet rails or pallet support bars above 4m, to increase Mechanical Handling productivity and improve safety of the operation
- Recommend to use column protectors when using Mechanical Handling equipment, that requires the straddle leg to go below bottom beam or between pallets and upright
- Mechanical Handling Equipment Specialist machine with either pantograph or telescopic forks, or using a purpose designed attachment, which can be fitted to standard reach truck
