Certified High-Density Drive-in Pallet Racking System for Heavy Duty Storage

Drive in pallet racking System is regarded as a high-density pallet racking storage system, which makes the best use of available space in the facility at the expense of selectivity. Consequently, it offers the highest possible density of pallet storage, but provides the lowest selectivity. Therefore, it is ideal for products with very fast rotation rate, which moves on a “first pallet in, last pallet out (FILO)” basis.

Drive-in pallet racks contain a series of tunnels with rails on either side, and pallets in drive in pallet racking system are directly placed on there rails. Each tunnel is storage space for pallets while at the same time serves as working aisle for forklifts. Forklifts can drive into every tunnel to load or unload pallets.

Usually, forklift operator will carry the first stored pallet to the deepest storing position so as to take best advantage of the space, then back pallets will be placed in front of the first pallet. The first pallet can not be accessed before removing other pallets, thus the first stored pallet will be the last one to pick up, which is called LIFO rotation order.

Characteristics and Benefits of Drive-in Pallet Racking System:

• High-density pallet racking system, with virtually unlimited depth.

• No specialized material handling equipment is needed.

• Drive in pallet rack is less expensive than dynamic storage solutions such as push-back pallet rack and pallet flow rack.

• Level storage medium: do not need to be concerned about height restriction in sloping systems like push back pallet rack and pallet flow rack.

• LIFO rotation order: when it is time to replenish cargoes, you need to ensure that tunnels are being fully emptied before replenishing.

• Significant reduction in pick slots, as there are fewer aisles and each tunnel can store only a single SKU, from floor to ceiling. For example, in a 4-level system, there are 4 times fewer pick slots on any aisle compared with other systems. In addition, compared to the standard selective pallet racking system, there are added slots lost since there are fewer aisles in a given floor area.

• Typically, observed capacity utilization is lower than for other systems, around 60%-70% is common.
