VNA and NA Trucks: There are certain truck models that have very narrow aisle or VNA features or narrow aisle or NA features. Nearly all counterbalanced trucks require at least 11 feet of aisle width in order to operate safely and efficiently. Narrow Aisle trucks on the other hand, could operate in narrow aisles that measure 8 to 10 feet wide. As well, VNA or very narrow aisle trucks could operate in aisles that are 6 feet wide.

The advantage of using an NA and VNA truck over a traditional lift is that it makes it possible for warehouses to be constructed with narrower aisles. The wider aisles in the warehouses allow for more storage of products within a specific space, that improves cube utilization. The loads transported utilizing Narrow Aisle and VNA trucks normally are limited to roughly 3000 and 5000 pounds. Reach trucks are capable of operating in narrow aisle. Rotating mast trucks, order selectors and turret trucks could work within very narrow or narrow aisles, depending on the specific unit.

Reach Trucks: Reach trucks are especially made narrow-aisle trucks that are made for storage and retrieval. They are made of telescoping forks and outriggers which allow the operators to lift a load and then retract it over the outriggers. These models are not the best suited for moving loads quickly over long distances nor for unloading or loading trucks. Similar to the order selector, reach trucks could be available for lifting heights that are greater than 30 feet.

Turret Trucks and Rotating-Mast Trucks: Like regular sit-down forklifts, rotating mast trucks have masts which could rotate in one direction, to a 90 degree angle. This feature allows them to operate within a narrow aisle condition. Turret trucks can operate in narrow or very narrow aisle places. Like order selectors, these machinery can elevate both the cargo and the operator. In addition, they can enable the operator to deal with loads on either side of an aisle without exiting and re-entering the aisle.

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