VNA and NA Trucks: There are certain truck models that have VNA or very narrow aisle features or NA or narrow aisle features. Nearly all counterbalanced trucks need a minimum of 11 feet of aisle width in order to function efficiently and safely. NA trucks on the other hand, could function in narrow aisles that are 8 to 10 feet wide. As well, VNA or very narrow aisle trucks can operate in aisles as narrow as 6 feet wide.
The benefit of utilizing a VNA and NA truck over a regular 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 within a particular area, that improves cube use. The loads moved by Very Narrow Aisle and NA trucks typically are limited to approximately 3000 and 5000 lbs. Reach trucks are capable of operating in narrow aisle. Turret trucks, rotating mast trucks and order selectors can operate within very narrow or narrow aisles, depending on the specific unit.
Reach Trucks: Reach trucks are particularly made narrow-aisle trucks that are made for storage and retrieval. They are made of telescoping forks and outriggers which enable the operators to pick up a load and after that retract it over the outriggers. These units are not suitable for transporting loads quickly over long distances nor for loading and unloading trucks. Like the order selector, reach trucks can be available for lifting heights which are greater than 30 feet.
Rotating-Mast Trucks and Turret Trucks: Like regular sit-down forklifts, rotating mast trucks have masts which are able to rotate in one direction, to a 90 degree angle. This feature enables them to function in a narrow aisle condition. Turret trucks could work in narrow or very narrow aisle locations. Similar to order selectors, these machines are capable of elevating both the load and the operator. Furthermore, 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 rail or wire guided when utilized within very narrow aisles. Therefore, the operator could focus 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 are able to be used for case and item picking as well as full pallet handling.
