NA and VNA Trucks: There are some truck types which have VNA or very narrow aisle features or NA or narrow aisle features. Most counterbalanced trucks need a minimum of 11 feet of aisle width in order to function efficiently and safely. Na or Narrow Aisle trucks on the other hand, can function in narrow aisles which measure 8 to 10 feet wide. Additionally, very narrow aisle or VNA trucks can function in aisles as narrow as 6 feet wide.
The advantage of using a VNA and NA truck over a conventional lift is that it makes it possible for warehouses to be built with narrower aisles. The wider aisles in the warehouses enable for more storage of products within a specific space, which improves cube utilization. The loads transported utilizing Narrow Aisle and VNA trucks usually are limited to roughly 3000 and 5000 pounds. Reach trucks can function in narrow aisle. Rotating mast trucks, order selectors and turret trucks could operate within very narrow or narrow aisles, depending on the particular model.
Reach Trucks: Particularly designed for storage and retrieval, reach trucks are made with outriggers and telescoping forks which enables the operator to lift and retract a load over the outriggers. These models are not suitable for transporting loads quickly over long distances nor for unloading or loading trucks. Similar to the order selector, reach trucks can be available for lifting heights that are higher than 30 feet.
Rotating-Mast Trucks and Turret Trucks: Like regular sit-down forklifts, rotating mast trucks have masts that can rotate in one direction, to a 90 degree angle. This feature enables them to function within a narrow aisle condition. Turret trucks can work in very narrow or narrow aisle places. Similar to order selectors, these machines are capable of lifting both the cargo and the operator. In addition, they can allow the operator to handle loads on either side of an aisle without exiting and re-entering the aisle.
Turret trucks are usually wire or rail guided when they are used in very narrow aisles. Therefore, the operator can focus on the work load at hand because they doesn't need to focus any energy on their driving skills. As turret trucks are considered "operator-up" trucks, they could be used for case and item picking in addition to full pallet handling.
