Narrow Aisle Forklift Trucks, or VNA are usually used and operated in warehouses.
It is a stand-up forklift, this means that the operator of the truck stands up when driving and operating the truck.
The main purpose of a VNA is pulling out and placing goods/stock on racks inside the warehouses. Its ideal for warehouses with narrow aisles, hence the name.
It is not commonly used to load trucks.
Narrow Aisle Forklifts are able to function in aisles between racking spaced closer together than the rack spacing in other warehouses. The forklift not only uses less space, it lets the warehouse owner increase holding capacity.
