Versatile High Density Double Deep Pallet Racking System for
Industrial Storage
The double-deep pallet racking system offers a higher storage
density than selective racking, making double-deep racking the
ideal solution for storing slightly larger quantities of the same
SKU. This warehouse-racking solution is suitable for a wide range
of product types, including food, beverage, hardware and products
(among others), making it the choice of companies operating in a
variety of industries.
Double-deep racking is typically applied with specially designed
double-deep forklifts equipped with pantographs to reach the rear
pallets. The double deep pallet racking requires the operator to
remove the front pallet before accessing the rear pallet, making it
more suitable for storing large quantities of the same items.
| Advantages of double deep pallet rack | Medium to low storage system |
| Floor level is not critical (front loaded) |
| Disadvantages of double deep pallet rack | Loss of storage locations as only same SKU can be stored in front
storage positions |
| Recommended storage loss allowance 15-20% |
| LIFO inventory management |
| Limited storage height (10m) |
| Special trucks required |
| Poor visibility of rear upper storage levels |
| Reduced through-put rates when compared with Reach Trucks |
Specification of Double Deep Pallet Rack Truck:
| Aisle Width | Storage Area | Operating Aisle Area | Through-put Rate | Lift Height |
| 3.0 to 3.5m (medium width) | 55% | 45% | 12-18pph | up to 9.5m |
Advantages and Features of Double Deep Pallet Racking System:
- Increased storage capacity compared to the selective pallet racking
system.
- Pallet access is kept simple and relatively quick, allowing for 50%
direct access and a reasonable turnover of goods.
- The system offers a good space utilization rate of all available
locations, typically above 80-90%.
- The intermediate system between adjustable selective pallet racking
systems and compact high-density systems.
- LIFO system, where the last pallet on the racking will be the first
to pick up.
- A more efficient system that eliminates unnecessary aisles and
increases the use of available space.
- Double-deep pallet racking systems are suitable for any type of
unit load.
- As with the adjustable pallet racking system, the assembly and
disassembly process and component replacement are quick and easy.
- Save time and effort in handling unit loads and achieve fast
inventory turnaround.
- Double deep pallet racking is designed to allow reconfiguration or
expansion of it to meet storage needs.
- High level of security due to the wide range of accessories that
can be combined.
Main Applications of Double Deep Racking for Pallets:
Double deep pallet racking system, thanks to its similarity to the
adjustable pallet racking system, offers a very versatile and
adaptable solution to a wide range of storage needs.
However, its greater storage capacity and reduced accessibility per
unit load make it particularly recommended for applications in
warehouses with the following characteristics:
- Warehouses that contain more than one product pallet per special
storage unit.
- Storage of the same or identical types of products.
- Warehouses with stock with a medium or long-term useful life.
Double deep pallet racking is a last-in, first-out system and is
not recommended for very perishable products.
- Warehouses with a robust inventory management system where
restricted access to all pallets is not an issue.
- Warehouses that need a balance between accessibility or selectivity
of unit loads and increased storage capacity.
