NA and VNA Trucks: There are some truck models that have VNA or very narrow aisle features or narrow aisle or NA features. The majority of counterbalanced trucks need a minimum of 11 feet of aisle width in order to operate efficiently and safely. Narrow Aisle trucks on the other hand, could function in narrow aisles that measure 8 to 10 feet wide. Moreover, VNA or very narrow aisle trucks can operate in aisles which are 6 feet wide.
NA and VNA trucks provide a lot of benefits since they make it possible for warehouses to be constructed with narrower aisles. This results in the warehouse being able to successfully store many more things within a particular area, improving cube utilization. The loads moved by Very Narrow Aisle and NA trucks typically are limited to about 3000 and 5000 lbs. Reach trucks are capable of operating in narrow aisle. Turret trucks, rotating mast trucks and order selectors are able to operate within very narrow or narrow aisles, depending on the particular unit.
Reach Trucks: Particularly designed for retrieval and storage, reach trucks are made with telescoping forks and outriggers which allows the operator to lift and retract a load over the outriggers. These units are not suitable for moving loads quickly over long distances nor for loading and unloading trucks. Similar to the order selector, reach trucks can be available for lifting heights that are higher than 30 feet.
Turret Trucks and Rotating-Mast Trucks: Like typical sit-down forklifts, rotating mast trucks have masts that 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 are able to operate in narrow or very narrow aisle places. Similar to order selectors, these machinery could lift both the operator and the load. Additionally, they can allow the operator to deal with loads on either side of an aisle without exiting and re-entering the aisle.
Turret trucks are usually wire or rail guided when they are used in very narrow aisles. This way, the operator could concentrate 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 can be used for case and item picking as well as full pallet handling.
