What Is Drive-In Racking?
Drive-in racking is a high-density storage system where forklifts drive directly into the rack structure to place and retrieve pallets. Pallets are stored on support rails, eliminating aisles between individual rack rows.
This system creates a block of storage where pallets are accessed from one end (LIFO - Last In, First Out) or both ends (FIFO - First In, First Out).
Advantages
Maximum Space Utilization
Drive-in racking can achieve 70-80% space utilization compared to 40% for selective racking. By eliminating aisles, you can store up to 75% more pallets in the same floor space.
Cost Efficiency
- Lower cost per pallet position than selective racking
- Reduced floor space requirements
- Fewer uprights and beams per pallet stored
Ideal for Bulk Storage
Perfect for seasonal products, cold storage, and operations with low SKU counts and high volume per SKU.
Disadvantages
Limited Selectivity
Only the last pallet in each lane is directly accessible. This makes drive-in unsuitable for operations requiring mixed-SKU storage.
Slower Throughput
Forklifts must enter and reverse out of each lane, which takes significantly longer than direct access picking in selective racking.
Higher Risk of Damage
Forklifts operating inside the rack structure have a higher likelihood of impacting rails and uprights, requiring regular inspections and more robust protective equipment.
Ideal Use Cases
- Cold storage facilities (maximizing expensive refrigerated space)
- Beverage distribution (high volume, low SKU)
- Seasonal inventory staging
- Buffer storage before shipping
When NOT to Use Drive-In
- High-SKU, low-quantity inventory
- Time-sensitive FIFO requirements (unless using drive-through)
- Mixed pallet sizes or weights in the same lane
- Operations with inexperienced forklift drivers
