VNA and NA Trucks: There are some truck types which have very narrow aisle or VNA features or NA or narrow aisle features. Nearly all counterbalanced trucks require a minimum of 11 feet of aisle width in order to function safely and efficiently. Na or Narrow Aisle trucks however, are able to operate in narrow aisles which are 8 to 10 feet wide. Also, very narrow aisle or VNA trucks can operate in aisles as narrow as 6 feet wide.
The advantage of utilizing a VNA and NA truck over a traditional lift is that it makes it possible for warehouses to be built with narrower aisles. The wider aisles within the warehouses enable for more storage of products in a particular area, that improves cube utilization. The loads transported utilizing NA and Very narrow Aisle trucks typically are limited to around 3000 and 5000 lbs. Reach trucks are capable of operating in narrow aisle. Turret trucks, rotating mast trucks and order selectors could work in very narrow or narrow aisles, depending on the particular unit.
Reach Trucks: Reach trucks are especially made narrow-aisle trucks which are made for storage and retrieval. They are made of telescoping forks and outriggers that allow the operators to lift a load and afterward retract it over the outriggers. These units are not suitable for loading and unloading trucks, nor for moving loads quickly over long distances. Like the order selector, reach trucks can be available for lifting heights which are greater than 30 feet.
Turret Trucks and Rotating-Mast Trucks: Rotating-mast trucks are like typical sit-down forklifts. The main difference is that their masts can rotate in one direction, to a 90 degree angle. This particular feature enables them to function within a narrow aisle situation. Turret trucks are able to work in narrow or very narrow aisle locations. Similar to order selectors, these machinery are capable of lifting both the operator and the cargo. Additionally, they can enable 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 in very narrow aisles. Thus, the operator can concentrate on the work load at hand because they doesn't need to focus any energy on their driving skills. Because turret trucks are considered "operator-up" trucks, they could be used for picking items and cases as well as full pallet handling.
