Drive-In / Drive-Thru Pallet Racking

Drive-In / Drive-Thru Pallet Racking

Drive-in and drive-thru racking are specialized types of pallet racking systems designed for high-density storage of homogeneous products with low stock turnover. These systems optimize warehouse space utilization by minimizing aisle space and maximizing vertical storage capacity.

Drive-In Racking: Drive-in racking is a system where pallets are stored in a continuous block without dedicated aisles between each storage lane. Pallets are loaded and retrieved using forklifts that drive directly into the rack structure. This allows forklifts to access multiple pallets in a deep lane.

Key features of drive-in racking include:

Last-In, First-Out (LIFO): Pallets are typically stored and retrieved in a Last-In, First-Out order. This means that the most recently loaded pallets are the first to be retrieved. It is suitable for products that do not require strict product rotation.

Reduced Aisle Space: Drive-in racking eliminates the need for individual aisles between storage lanes. The forklifts drive into the rack structure, maximizing storage density by utilizing vertical space.

Structural Considerations: Drive-in racking requires robust rack structures to support the weight of the pallets. The racks have fewer vertical beams to allow forklift access, requiring careful consideration of the structural integrity and load-bearing capacity.

Drive-Thru Racking: Drive-thru racking, also known as drive-through racking, is similar to drive-in racking in terms of design and function. The key difference is that drive-thru racking has separate entry and exit points on opposite sides of the rack structure.

Key features of drive-thru racking include:

First-In, First-Out (FIFO) or Last-In, First-Out (LIFO): Drive-thru racking can be configured for either FIFO or LIFO storage and retrieval methods. FIFO allows for strict product rotation as pallets are loaded from one side and retrieved from the opposite side. LIFO is achieved by loading and retrieving pallets from the same side.

Increased Accessibility: Drive-thru racking provides improved accessibility compared to drive-in racking. Forklifts can access pallets from both ends of the rack structure, allowing for more flexibility in product retrieval.

Aisle Configuration: Drive-thru racking requires separate entry and exit aisles. This allows forklifts to enter from one side to load or retrieve pallets and exit from the opposite side. Adequate space is needed for maneuvering and safe operations.

Both drive-in and drive-thru racking systems offer high-density storage solutions but have different considerations regarding inventory management, product rotation, and accessibility. They are commonly used in operations where large quantities of the same product are stored and the retrieval sequence is not critical or can be controlled based on inventory needs. Careful planning and consideration of specific operational requirements are crucial when implementing these systems to ensure optimal storage efficiency.
