Very Narrow Aisle Pallet Racking

Very Narrow Aisle Pallet Racking

Very Narrow Aisle (VNA) pallet racking is a specialized type of pallet racking system designed to maximize storage density and optimize warehouse space utilization. It is specifically used in warehouses or distribution centers where space is limited, and efficient storage is crucial.

VNA pallet racking systems are characterized by narrower aisles compared to traditional selective pallet racking systems. These aisles are typically between 1.8 to 2.5 meters (6 to 8 feet) wide, allowing for the efficient use of space by reducing aisle widths while still accommodating specialized handling equipment.

The key features and considerations of very narrow aisle pallet racking include:

Specialized Handling Equipment: VNA systems require the use of specialized handling equipment, such as turret trucks or guided wire/track systems. These equipment types are designed to operate within the narrow aisles, maneuvering and retrieving pallets with precision.

Increased Height: VNA systems are designed to utilize vertical space efficiently. The racking system is typically constructed with taller upright frames, allowing for higher stacking heights. This maximizes the storage capacity by utilizing the full height of the warehouse.

Rack Configuration: VNA pallet racking systems are typically configured as single or double deep systems. Single deep systems allow access to individual pallets, while double deep systems enable storage of two pallets deep on each side of the aisle. This configuration requires specific handling equipment that can reach and retrieve pallets from the inner positions.

Wire or Rail Guidance: To ensure precise movement and alignment of handling equipment within the narrow aisles, VNA systems often incorporate wire or rail guidance systems. These systems help guide the equipment along the designated path, ensuring accuracy and safety during operations.

Safety Considerations: Due to the reduced aisle widths, safety considerations are paramount in VNA systems. Proper training and operating protocols for handling equipment operators are essential. Safety features such as proximity sensors, aisle-end barriers, and safety gates are commonly employed to enhance operational safety.

The primary benefits of very narrow aisle pallet racking include increased storage density, optimized space utilization, and improved inventory control. By utilizing narrower aisles and taller heights, VNA systems allow warehouses to store more pallets in the available space. Additionally, the efficient handling equipment and optimized storage layout enable faster and more accurate order picking and inventory management.

It's important to note that implementing a VNA pallet racking system requires careful planning, as it involves specific warehouse layout considerations, specialized equipment, and safety requirements. Consulting with experienced professionals or storage system providers is advisable to ensure the system is designed and implemented correctly based on specific operational needs and safety standards.
