VNA Racking

Very Narrow Aisle racking commonly referred to as VNA is an effective method of increasing pallet storage with in a given area with the advantages of selective racking. This system requires a special fork lift which reduces the aisle space by a minimum of 40% compared to traditional fork lifts. This system still provides 100 % product selectivity and utilizes the vertical space for pallet storage.

Pallet Racking Systems are designed to meet the new generation of warehouses up to 15m high, designed around the operating tolerances of VNA equipment with aisles marginally wider than the load. Such structures must have a high level of rigidity and accurate manufacturing tolerances, our systems are designed to meet these critical requirements.

Increased capacity with increased height
Warehouse capacity can be increase by an additional 40% over Selective Pallet racking by increasing operational height and the reduction of operation aisle.


Optimal operation
Radio frequency (RF) controls on the Material handling (MH) equipment will ensure maximum pallet cycles per hour. A smaller reach or counterbalance is generally used in conjunction with the operation of the VNA MH machine, to maximize operation when within the aisle.

High-Bay Storage Advantages

  • Good stock rotation
  • Good order picking: 100% selectivity
  • Fast picking rate
  • Good product protection
  • 50% net pallet area usage of overall warehouse area
  • Limited pallet redundancy as system can run at 95%+ capacity
  • Uses guide rails or wire guidance for fast movement in aisle
