VNA and NA Trucks: There are certain truck types that have very narrow aisle or VNA features or narrow aisle or NA features. Most counterbalanced trucks need at least 11 feet of aisle width to be able to operate efficiently and safely. Na or Narrow Aisle trucks however, can operate in narrow aisles which measure 8 to 10 feet wide. What's more, very narrow aisle or VNA trucks can function in aisles which are 6 feet wide.
The benefit of utilizing a VNA and NA 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 allow for more storage of things within a particular space, that improves cube use. The loads moved utilizing VNA and Narrow Aisle trucks typically are limited to approximately 3000 and 5000 pounds. Reach trucks could function in narrow aisle. Order selectors, turret trucks and rotating mast trucks are able to operate in narrow or very narrow aisles, depending on the specific model.
Reach Trucks: Specifically designed for retrieval and storage, reach trucks are made with telescoping forks and outriggers that allows the operator to pick up and retract a load over the outriggers. These units are not suitable for unloading or loading trucks, nor for transporting loads quickly over long distances. Similar to the order selector, reach trucks could be available for lifting heights that are greater than 30 feet.
Rotating-Mast Trucks and Turret Trucks: Rotating-mast trucks are similar to regular sit-down forklifts. The main difference is that their masts 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 can work in narrow or very narrow aisle locations. Similar to order selectors, these equipment are capable of lifting both the cargo and the operator. Furthermore, 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 in very narrow aisles. Thus, the operator doesn't have to focus any energy on their driving skills and could concentrate on the work load at hand. Since turret trucks are considered "operator-up" trucks, they could be used for picking cases and items as well as full pallet handling.
