VNA and NA Trucks: There are some truck types which have very narrow aisle or VNA features or narrow aisle or NA features. Nearly all counterbalanced trucks need a minimum of 11 feet of aisle width in order to operate safely and efficiently. NA trucks on the other hand, can function in narrow aisles that measure 8 to 10 feet wide. As well, very narrow aisle or VNA trucks could function in aisles that are 6 feet wide.
The advantage of using a VNA and NA truck over a conventional lift is that it makes it possible for warehouses to be constructed with narrower aisles. The wider aisles in the warehouses allow for more storage of things within a particular space, that improves cube utilization. The loads moved utilizing Narrow Aisle and VNA trucks usually are limited to approximately 3000 and 5000 lbs. Reach trucks could operate in narrow aisle. Rotating mast trucks, order selectors and turret trucks could work in narrow or very narrow aisles, depending on the specific unit.
Reach Trucks: Reach trucks are especially designed narrow-aisle trucks that are designed for retrieval and storage. They are made of telescoping forks and outriggers which allow the operators to pick up a load and then retract it over the outriggers. These units are not suitable for unloading or loading trucks, nor for moving loads quickly over long distances. Similar to the order selector, reach trucks can be available for lifting heights which are greater than 30 feet.
Rotating-Mast Trucks and Turret Trucks: Rotating-mast trucks are similar to regular sit-down forklifts. The main distinction is that their masts are able to rotate in one direction, to a 90 degree angle. This feature allows them to function in a narrow aisle condition. Turret trucks can operate in very narrow or narrow aisle places. Like order selectors, these equipment can elevate both the cargo and the operator. Additionally, they can allow the operator to deal with 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 in very narrow aisles. This way, the operator doesn't need to focus any energy on their driving skills and can concentrate on the work load at hand. Because turret trucks are considered "operator-up" trucks, they are able to be used for picking items and cases in addition to full pallet handling.
