Narrow Aisle Pallet Racking - Increasing Density

Maximise Usable Racking Space

Narrow aisle racking and very narrow aisle racking (VNA) can offer some of the same flexibility as wide aisle racking. However, by reducing aisle width and storing pallets to a greater height, storage density is increased. It still allows access to individual pallets, whilst retaining full system adjustability. Aisles can be as narrow as 1.8 metres.

Narrow aisle racking requires specialist fork-trucks. However, the higher storage densities make it a cost-effective investment, offset by the enhanced access and space utilisation. Specialist VNA trucks, often featuring a man-up function, are guided either by wires embedded in the floor or guidance rails at ground level. This guidance enables good speed in aisles, though these trucks primarily operate in aisles. The man-up function can speed up high-level picking, including individual case picks.

Bendi or Flexi-trucks can also be used with narrow aisle pallet racking, with aisles as narrow as 1.9 metres. However, these trucks are not guided, making them slower and reducing their height capability. They offer flexibility as both yard and in-rack trucks.

Another popular storage solution is wide aisle pallet racking designed to maximise accessibility and efficiency in warehouse environments. With aisles typically ranging from 2.5 to 3.5 meters wide, this system accommodates standard forklifts and pallet trucks, allowing for easy movability and quick access to each pallet.


We work nationally for pallet racking across the UK with a large number of blue-chip clients and have a particularly strong following of SMEs.

Shuttle Racking System

For clients for whom ultra-high density pallet storage is important, a shuttle racking system can be the answer. The concept is based around the fact that the forklift never enters the racking, individual pallet movements being conducted on intelligent RF guided shuttles that operate on rails millimetres below each pallet.
