NA and VNA Trucks: There are some truck models that have very narrow aisle or VNA features or NA or narrow aisle features. Most counterbalanced trucks need a minimum of 11 feet of aisle width in order to operate efficiently and safely. Na or Narrow Aisle trucks however, can operate in narrow aisles which measure 8 to 10 feet wide. Furthermore, very narrow aisle or VNA trucks could operate in aisles as narrow as 6 feet wide.
The advantage of utilizing an NA and VNA truck over a regular lift is that it makes it possible for warehouses to be constructed with narrower aisles. The wider aisles within the warehouses enable for more storage of things within a particular space, which improves cube use. The loads transported using Narrow Aisle and Very narrow Aisle trucks typically 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 can operate within very narrow or narrow aisles, depending on the specific unit.
Reach Trucks: Reach trucks are particularly designed narrow-aisle trucks which are designed for retrieval and storage. They are made of outriggers and telescoping forks which allow the operators to lift a load and after that 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. Like the order selector, reach trucks could be available for lifting heights which are greater than 30 feet.
Turret Trucks and Rotating-Mast Trucks: Rotating-mast trucks are similar to standard 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 situation. Turret trucks can operate in narrow or very narrow aisle locations. Similar to order selectors, these machinery are capable of lifting both the cargo and the operator. Moreover, they could allow the operator to handle loads on either side of an aisle without exiting and re-entering the aisle.
Turret trucks are generally rail or wire guided when they are utilized within very narrow aisles. This way, the operator can concentrate on the work load at hand since 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 picking items and cases in addition to full pallet handling.
