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.
- High storage density for certain product mixes
- Low capital investment vs. other high density options
- Very efficient storage (ability to store pallets back-to-back without aisles)
- Inflexible, does not allow for SKU increase
- Possible low storage utilization (typically 50% of positions used)
- Low productivity (30% slower than alternative systems)
- Requires standardized pallets
- Risk of rack damage by fork trucks
- LIFO – Last In First Out
- Difficult to rotate time sensitive products
Structural Pallet Rack Types
Selective Rack accommodates flexibility in slotting design, which is ideal for high turnover, high SKU stock count and quick product accessibility. Selective pallet rack is a cost-effective design allowing for the maximum number of SKU pick facings available in standard rack.
Store 2 pallet positions from a single aisle (4 pallets back to back) with the Double Deep Selective Pallet Rack. The Double Deep Reach warehouse racking system provides high-density storage at a lower initial capital cost when compared with other high-density storage systems.
The 2 Wide DITM warehouse storage rack delivers maximum efficiency for high density storage. This racking system allows twice the loading and unloading capacity in a single run while increasing forklift stability.
Designed for high-volume applications, Pick Module pallet racks are designed for high-volume applications and are the perfect industrial storage solutions for full and split case picking. Modules will often incorporate carton flow, pallet flow, pushback and other custom racking combinations.
High Bay industrial storage systems can exceed 60′ in height, nearly doubling the storage capacity of conventional systems (fully-automated and man up vehicles available). Some of the racking systems available through ASP allow vehicles to be moved between aisles to reduce initial capital costs.
