Drive-In Pallet Racking

Drive In Pallet Racking


Drive-In Racking is a high density pallet storage system where the outer sides of the pallet are supported on rails. The rails create a lane, and the length of the rails determine how many pallets deep the system will be. Typically, the depth of the system will be from 2 – 10 pallets, but it can be deeper.

The forklift aisle runs perpendicular to the drive in lanes, and a single aisle can service many lanes on either side, providing a very high pallet position-to-aisle ratio. The operator drives into the required lane to store and retrieve pallets.


Advantages

  • Density – This system is designed to maximize the number of pallet locations in a given footprint.
  • Investment – Drive In racking is more expensive per pallet position vs. selective or double deep racking, but is the least expensive high density system


Disadvantages

  • Selectivity – All pallet locations, (depth and height), within a particular lane should be filled with the same SKU. This means that for a large number of pallet positions only one SKU is directly available to be picked.
  • Honeycombing – As stock is partially depleted from a particular lane pallet positions are left open, creating the honeycomb effect. These positions will remain open until new product is received. Usually operators will want to deplete an entire lane prior to receiving new product into the lane to ensure the stock is rotated. If new product is received into the forward positions then the older product will not be rotated out of inventory.
  • Inventory Rotation – The system is designed to provide Last In, First Out, (LIFO) inventory rotation, however FIFO can be achieved at a batch level if procedures are in place to support the process and the system is properly configured with this in mind.
  • Damages – This system is highly susceptible to damages with forklift operators working inside confined lanes. Guarding and guides are essential to prevent destruction of the system over time and the system should be inspected and maintained regularly.
  • Flexibility – The systems are designed and engineered for particular load dimensions and weights. Reconfiguration, while possible, can be time consuming and expensive.

 

Best Suited For – Low mix, High volume SKU’s



Layout and Equipment Considerations

  • Material Handling Equipment – Standard forklifts and reach trucks can be used, but the system must be designed to accommodate the equipment or vice versa.
  • Pallet Construction and condition – It is important to ensure that pallets are in good condition and capable of supporting the loads from the side. Pallets should be stable and without product overhang.
  • Slab – Due to the density of the system, these systems can have higher than normal load requirements for the slab.
