Drive-In rack systems provide a low-budget and high-density storage solution for customers with lower SKU counts.  Drive-In rack systems load from the back to the front (First-In Last-Out) as the forklift literally drives into the rack system, loads the pallet onto rails and backs out of the rack system.  As the system is loaded rear to front, it must it be unloaded front to rear.

Drive-In systems reduce the number of aisles required in a warehouse.  It is frequently used in cold storage applications, where the cost of (refrigerated) volume is at its highest and requires the most return on investment (more density).

Drive-In is limited by the warehouse management system and its ability to slot pallet locations.  Utilization is typically low due to honeycombing and drive-in rack is subject to more abuse due to the constant movement of fork lifts in and out of the rack.  It is also a system that can require a pallet to be handled multiple times before shipping.  If multiple SKU’s or manufacture dates are stored in a bay, handling product multiple times can lead to product damage.
