NA and VNA Trucks: There are some truck models which have very narrow aisle or VNA features or narrow aisle or NA features. Most counterbalanced trucks require at least 11 feet of aisle width in order to operate efficiently and safely. NA trucks however, are able to function in narrow aisles that are 8 to 10 feet wide. Furthermore, VNA or very narrow aisle trucks can function in aisles as narrow as 6 feet wide.
VNA and NA trucks offer many advantages as they make it possible for warehouses to be constructed with narrower aisles. This results in the warehouse being able to successfully store numerous more things in a particular area, improving cube use. The loads transported using VNA and Narrow Aisle trucks usually are limited to about 3000 and 5000 pounds. Reach trucks are capable of operating in narrow aisle. Turret trucks, rotating mast trucks and order selectors are able to operate within narrow or very narrow aisles, depending on the specific model.
Reach Trucks: Specifically made for storage and retrieval, reach trucks are made with telescoping forks and outriggers which allows the operator to lift and retract a load over the outriggers. These models are not the best suited for loading and unloading trucks, nor for moving loads quickly over long distances. Similar to the order selector, reach trucks could be available for lifting heights that are higher than 30 feet.
Rotating-Mast Trucks and Turret Trucks: Rotating-mast trucks are like standard sit-down forklifts. The main distinction is that their masts can rotate in one direction, to a 90 degree angle. This feature allows them to operate in a narrow aisle condition. Turret trucks can operate in very narrow or narrow aisle places. Similar to order selectors, these equipment are capable of elevating both the cargo and the operator. Additionally, they could enable the operator to deal with loads on either side of an aisle without re-entering and exiting the aisle.
Turret trucks are normally rail or wire guided when they are used in very narrow aisles. Therefore, the operator doesn't have to focus any energy on their driving skills and could focus on the work load at hand. Since turret trucks are considered "operator-up" trucks, they can be utilized for case and item picking as well as full pallet handling.
