Narrow Aisle and very Narrow Aisle Trucks: Certain forklifts have VNA features or NA features. To be able to function efficiently and safely, nearly all counterbalanced trucks require at least 11 feet of aisle width. NA trucks however, could operate in narrow aisles which measure 8 to 10 feet wide. What's more, very narrow aisle or VNA trucks could operate in aisles as narrow as 6 feet wide.

The advantage of using an NA and VNA truck over a conventional lift is that it makes it possible for warehouses to be constructed with narrower aisles. The wider aisles in the warehouses enable for more storage of things in a specific area, which improves cube use. The loads moved using NA and VNA trucks usually are limited to approximately 3000 and 5000 pounds. Reach trucks are capable of operating in narrow aisle. Order selectors, turret trucks and rotating mast trucks can operate within very narrow or narrow aisles, depending on the particular model.

Reach Trucks: Reach trucks are especially made narrow-aisle trucks that are designed for retrieval and storage. They are made of telescoping forks and outriggers that enable the operators to pick up a load and then retract it over the outriggers. These units are not suitable for unloading or loading trucks, nor for moving loads quickly over long distances. Similar to the order selector, reach trucks can be available for lifting heights that are higher than 30 feet.

Turret Trucks and Rotating-Mast Trucks: Rotating-mast trucks are similar to regular sit-down forklifts. The main distinction is that their masts could rotate in one direction, to a 90 degree angle. This particular feature enables them to function within a narrow aisle condition. Turret trucks could work in narrow or very narrow aisle places. Like order selectors, these machinery are capable of elevating both the operator and the load. Moreover, they could allow the operator to handle loads on either side of an aisle without re-entering and exiting the aisle.

Turret trucks are normally wire or rail guided when they are utilized within very narrow aisles. Therefore, the operator can concentrate on the work load at hand as they doesn't need to focus any energy on their driving skills. Because turret trucks are considered "operator-up" trucks, they could be used for case and item picking as well as full pallet handling.
