12m to 18m
The height of narrow aisle racks is usually designed between 12m and 18m. Specifically, the height of narrow aisle racks can be designed to be between 12m and 15m, or even up to 18m. This height design can make full use of the vertical space of the warehouse and significantly improve storage density and storage capacity.
The aisle width of narrow aisle racks is generally between 1.5m and 2m. This narrow aisle design allows more shelves to be placed in the same warehouse area, further increasing storage density. In addition, the bottom ground of the narrow aisle rack is equipped with a "three-way stacking forklift" action rail, providing a 100% picking rate, but the clear height of the warehouse needs to be at least 8m, and a special three-way stacking forklift must be used for operation.
