Narrow Aisle Pallet Racking

What is Narrow Aisle Pallet Racking?

Narrow aisle racking is able to offer a much denser storage area than any other form of pallet racking, as it uses narrower aisles which maximises the storage capacity of a warehouse. Narrow aisle pallet racking requires specialised forklifts, often referred to as very narrow aisle (VNA) trucks, which are designed to manoeuvre in tight spaces and reach higher racks. Narrow aisle pallet racking (including very narrow aisle pallet racking) is especially suitable for warehouses that require high-density storage and have a wide variety of products.

The technical specifications of narrow aisle pallet racking systems can vary based on the manufacturer, the specific design, and the requirements of the warehouse. However, there are common features and specifications that are generally found in these systems:

• Aisle Width: Narrow aisle pallet racking typically requires aisles between 1.6 to 2.0 meters wide, much narrower than conventional pallet racking systems.
• Rack Height: These systems often make use of vertical space more effectively than traditional racking systems. Rack heights can extend up to 15 meters or even higher, depending on the warehouse’s ceiling height and the capacity of the material handling equipment.
• Beam Length: The length of the beams can vary to accommodate different pallet sizes and weights. It’s crucial to match beam length with pallet size to ensure efficient storage and safety.
• Load Capacity: Each level in a narrow aisle racking system can typically hold a significant amount of weight, often ranging from 500 to 5000 kilograms per level. The total capacity will depend on the design and materials used in the racking system.
• Rack Material: High-grade steel is commonly used for its strength and durability. The specifications of the steel (such as its gauge) will impact the overall load capacity and longevity of the racking system.
• Guidance System: Rail or wire guidance systems are used to assist the operation of forklifts within the narrow aisles. These systems help to prevent damage to the racks and improve safety by guiding the forklifts precisely.

Other technical elements include splices and shims to connect, repair or level out racking sections, locking pins, row spacers, aisle ties and holding down bolts. Each installation will vary in the technical specifications your company will need and when we design your narrow aisle pallet racking we will discuss the technical specifications you need.

Narrow aisle pallet racking systems can be enhanced and customised with a variety of accessories designed to improve functionality, safety and efficiency. Here are some of the commonly available accessories:

• Wire Mesh Decks: These are placed over the beams to provide a stable and secure platform for pallets and prevent pallets or goods from falling through the rack levels.
• Pallet Support Bars: These bars are particularly useful for pallets that are not wide enough to span the distance between the beams.
• Column Protectors: Column protectors absorb impact and reduce the risk of structural damage to the racking system should there be an impact from a forklift.
• Load Stops: These are barriers attached to the back or sides of the racks to prevent pallets from being pushed too far and falling off the other side.
• Row Spacers: These are used to maintain consistent spacing between back-to-back rows of racking, providing stability and uniformity.
• Rack End Barriers: These protectors are placed at the ends of rack rows to shield them from collision damage, particularly from forklifts.
• Labelling and Signage: Proper labelling is essential for efficient operation. Labels and signs can help with quick identification of products, safety warnings, and navigation within the warehouse.
• Anti-Collapse Mesh (ACM): Installed on the back of rack rows, this mesh prevents items from falling off and causing accidents or product damage.

Other accessories include fork entry bars, drum chocks, stillage skids and steel and mesh decking to prevent goods from falling through the racking onto something or someone at the opposite side of the aisle or to support the pallet load if the pallet is of poor strength or to store loose hand-loaded items such as boxes. All of our narrow aisle pallet racking accessories are able to ensure your narrow aisle pallet racking installation is as efficient and safe as possible.
