Very Narrow Aisle and Narrow Aisle Trucks: Some forklifts have VNA features or NA features. To be able to function safely and efficiently, nearly all counterbalanced trucks need at least 11 feet of aisle width. Na or Narrow Aisle trucks on the other hand, are able to function in narrow aisles that measure 8 to 10 feet wide. Furthermore, VNA or very narrow aisle trucks can function in aisles that are 6 feet wide.
NA and VNA trucks offer numerous benefits since they make it possible for warehouses to be built with narrower aisles. This results in the warehouse being able to successfully store numerous more things in a specific area, improving cube utilization. The loads transported utilizing VNA and NA trucks typically are limited to about 3000 and 5000 lbs. Reach trucks are capable of operating in narrow aisle. Order selectors, turret trucks and rotating mast trucks could operate within narrow or very narrow aisles, depending on the particular unit.
Reach Trucks: Reach trucks are specially designed narrow-aisle trucks that are made for storage and retrieval. They are made of telescoping forks and outriggers that enable the operators to pick up a load and afterward retract it over the outriggers. These units are not the best suited for transporting loads quickly over long distances nor for loading and unloading 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 like regular 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 operate in a narrow aisle condition. Turret trucks are able to operate in narrow or very narrow aisle places. Similar to order selectors, these machinery can lift both the operator and the load. Additionally, they could allow the operator to handle loads on either side of an aisle without re-entering and exiting the aisle.
Turret trucks are generally wire or rail guided when they are used within very narrow aisles. Therefore, the operator doesn't need 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 could be used for picking items and cases in addition to full pallet handling.
