Double Deep Racking
Double Deep Racking is alike to selective racking; however pallets are stored in two rows deep instead of one. Specialised pallet handling equipment is a requisite in this type of racking.
Double deep is ideal to products that have minimum of four or five pallets per SKU : IC, allowing rotation of two-deep lanes to provide practical location utilization. However, this type of racking can’t give instant access to each individual pallet; thus, it does not work for strict first-In-first-Out storage. Moreover, the pallet position use of double deep racking inclines to be higher than the denser storage systems but not as high comparing to single-deep racking. To serve double deep racking, special reach trucks are required. This enables forks to extend far enough to reach the rear pallet. Telescopic forks or extending outward scissor mechanism can be used to achieve the best results. However, reach trucks require a counter balance for unloading and loading pallets, which can double capital investment requirements for your pallet handling equipment.
To help you with this rack type purchase, here’s and in-depth look in the various pallet handling options of Double deep racking.
- Telescopic/Hydraulic Attachments:
This is well-suited for double deep racking handling because it allows non-pantograph forklifts to act as a handle for double deep pallet racking. The hydraulic pumps, controlled by a forklift operator, move the forks inward and outward placing stock into the second row of a double deep racking system.
The main advantages of hydraulic attachment are low capital investment, reduced aisle width scope and stock damage, and riddance of extra obstructions. The downside of this handling attachment is it lowers the forklift lifting capacity.
- Scissor/Pantograph mast trucks
This type of reach trucks operates faster than the hydraulic fork attachments. Because of its smooth operation in handling double deep racks, it reduces pallet damage. But, one has to be cautious with counter balance trucks for unloading and loading of freight tracks. This is an ideal for big budget businesses.
