VNA stands for ” Very Narrow Aisle “. Some equipment handling equipment requires narrow aisles, for example less than 2 meters. Therefore, more pallet operations can be performed compared to other MHEs.
The VNA can reach a height of 12 meters. VNA racks are Selective Pallet Racks only, but can exceed VNA equipment. Mechanical rails are widely used for convenience and economy.
However, VNA equipment places high demands on the accuracy of the backplane.
