VNA and NA Trucks: There are some truck models that have very narrow aisle or VNA features or NA or narrow aisle features. Nearly all counterbalanced trucks need a minimum of 11 feet of aisle width in order to function efficiently and safely. Narrow or NA trucks on the other hand, could operate in narrow aisles that measure 8 to 10 feet wide. Furthermore, VNA or very narrow aisle trucks can operate in aisles which are 6 feet wide.
The advantage of using a VNA and NA truck over a standard lift is that it makes it possible for warehouses to be constructed with narrower aisles. The wider aisles within the warehouses allow for more storage of things in a specific area, which improves cube utilization. The loads transported using NA and VNA trucks normally are limited to approximately 3000 and 5000 lbs. Reach trucks are capable of operating in narrow aisle. Order selectors, turret trucks and rotating mast trucks are able to work in very narrow or narrow aisles, depending on the specific unit.
Reach Trucks: Particularly made for retrieval and storage, reach trucks are made with outriggers and telescoping forks that enables the operator to lift and retract a load over the outriggers. These models are not the best suited for unloading or loading trucks, nor for transporting loads quickly over long distances. Similar to the order selector, reach trucks can be available for lifting heights which are higher than 30 feet.
Rotating-Mast Trucks and Turret Trucks: Rotating-mast trucks are similar to typical sit-down forklifts. The main distinction is that their masts can 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 work in very narrow or narrow aisle places. Like order selectors, these machinery can lift both the load and the operator. Furthermore, they could allow the operator to handle loads on either side of an aisle without re-entering and exiting the aisle.
Turret trucks are usually rail or wire guided when used within very narrow aisles. Thus, the operator doesn't need to focus any energy on their driving skills and could concentrate on the work load at hand. Since turret trucks are considered "operator-up" trucks, they can be used for picking items and cases in addition to full pallet handling.
