Very Narrow Aisle Racking (VNA)

For warehouse operators struggling with limited floor space, the challenge is real: how can you store more pallets without losing accessibility? The solution is Very Narrow Aisle (VNA) Racking — a high-density pallet racking system designed to maximize every square meter of your warehouse.

What is VNA Racking?

Very Narrow Aisle (VNA) racking is a specialised version of selective pallet racking. Its defining feature is the extremely narrow aisle space between racks, often measuring just 1.8 to 2.0 metres wide. To put that in perspective, this can reduce the amount of floor space dedicated to aisles by over 50% compared to a setup for a standard counterbalance forklift.

This space saving is achieved without compromising on the system’s core function. You still have direct, individual access to every pallet, making VNA a powerful solution for businesses that need both high density and high selectivity for a large number of different products (SKUs).

How VNA Racking Works: The Role of Specialised Equipment

Operating safely and efficiently in such tight confines is impossible with standard forklifts. A VNA system is defined by the specialised material handling equipment it requires.

Specialised VNA Forklifts

These machines are precision-engineered for operating at height in narrow spaces. The two primary types are:

• Turret Trucks: These are the most common VNA vehicles. Their forks are mounted on a mast that can rotate 90 degrees to the left or right, allowing the operator to pick and place pallets without turning the truck itself.
• Man-Up Order Pickers: In these vehicles, the entire operator cabin elevates with the forks. This gives the operator an excellent view when handling pallets at significant heights, improving safety and accuracy.

Precision Guidance Systems

To ensure the forklift navigates the narrow aisle without colliding with the racking, a guidance system is essential. This technology keeps the truck on a perfectly straight path, allowing the operator to focus on lifting and handling loads. Common methods include:

• Wire Guidance: An electromagnetic wire is embedded in the concrete floor, which the truck’s sensors follow.
• Rail Guidance: Steel rails are fixed to the floor at the base of the racking, and rollers on the truck guide it along the aisle.

The Key Benefits of a VNA Racking System

Investing in a VNA system is a strategic decision that delivers transformative results for your warehouse.

Exceptional Increase in Storage Capacity

By converting wasted aisle space into valuable storage locations, a VNA system can increase your warehouse storage capacity by 40-50%. This allows you to store significantly more product within your existing facility, avoiding the immense cost of relocation or expansion.

Maximum Use of Vertical Height

VNA trucks are designed to operate at incredible heights, often reaching over 12 metres. This allows you to take full advantage of your building’s vertical cube, turning unused overhead space into profitable storage.

Total Pallet Selectivity

This is the key advantage of VNA over other high-density systems like Drive-In. You maintain 100% direct and immediate access to every pallet, which is crucial for operations with diverse product ranges and complex inventory management needs.

Improved Productivity

With aisles optimised for specific tasks and reduced travel distances for forklifts, put-away and retrieval cycles become much faster. This leads to higher throughput and improved overall operational productivity.

Is VNA Racking the Right Solution for Your Warehouse?

While incredibly powerful, a VNA system is a specialised solution and a significant investment. It is the perfect choice for operations where:

• Floor space is extremely limited or comes at a high cost.
• The facility has high ceilings that are currently underutilised.
• The inventory consists of a large number of different SKUs requiring both high storage density and direct access.
• High-volume throughput is a key operational requirement.

A critical consideration is your warehouse floor. VNA systems require a “super-flat” floor to operate safely and effectively at height. Our engineering team can conduct a detailed analysis to assess your floor’s suitability as part of the consultation process.

Reach New Heights in Warehouse Efficiency

For businesses that have reached the limits of their floor space but still need to grow, VNA racking is the ultimate solution. It offers an unparalleled combination of maximum storage density and perfect pallet selectivity, allowing you to optimise your facility to its absolute fullest potential.
