Very Narrow Aisle and Narrow Aisle Trucks: Some forklifts have NA features or VNA features. In order to operate safely and efficiently, most counterbalanced trucks need at least 11 feet of aisle width. NA trucks on the other hand, are able to function in narrow aisles which measure 8 to 10 feet wide. As well, VNA or very narrow aisle trucks can operate in aisles that are 6 feet wide.

VNA and NA trucks provide a lot of advantages since they make it possible for warehouses to be built with narrower aisles. This results in the warehouse being able to successfully store numerous more products within a certain area, improving cube utilization. The loads transported by NA and VNA trucks usually are limited to roughly 3000 and 5000 pounds. Reach trucks could operate in narrow aisle. Rotating mast trucks, order selectors and turret trucks are able to work within narrow or very narrow aisles, depending on the particular unit.

Reach Trucks: Particularly designed for retrieval and storage, reach trucks are made with telescoping forks and outriggers which enables the operator to pick up and retract a load over the outriggers. These units are not suitable for moving loads quickly over long distances nor for loading and unloading trucks. Similar to the order selector, reach trucks can be available for lifting heights which are higher than 30 feet.

Turret Trucks and Rotating-Mast Trucks: Like typical sit-down forklifts, rotating mast trucks have masts that are able to rotate in one direction, to a 90 degree angle. This particular feature enables them to operate in a narrow aisle condition. Turret trucks could work in narrow or very narrow aisle places. Similar to order selectors, these machinery could elevate both the operator and the load. Moreover, they are able to allow the operator to deal with loads on either side of an aisle without re-entering and exiting the aisle.

Turret trucks are often wire or rail guided when used within very narrow aisles. This way, the operator doesn't have to focus any energy on their driving skills and can concentrate on the work load at hand. Because turret trucks are considered "operator-up" trucks, they are able to be utilized for picking items and cases as well as full pallet handling.
