VNA and NA Trucks: There are certain truck models which have VNA or very narrow aisle features or narrow aisle or NA features. Most counterbalanced trucks need at least 11 feet of aisle width to be able to function efficiently and safely. NA trucks on the other hand, could operate in narrow aisles which measure 8 to 10 feet wide. As well, very narrow aisle or VNA trucks could operate in aisles as narrow as 6 feet wide.
The advantage of utilizing 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 within the warehouses allow for more storage of products in a particular area, that improves cube utilization. The loads moved utilizing Very Narrow Aisle and NA trucks usually are limited to around 3000 and 5000 lbs. Reach trucks could operate in narrow aisle. Rotating mast trucks, order selectors and turret trucks are able to operate in very narrow or narrow aisles, depending on the particular unit.
Reach Trucks: Reach trucks are especially made narrow-aisle trucks that are made for storage and retrieval. They are made of outriggers and telescoping forks that allow the operators to lift a load and then retract it over the outriggers. These models are not the best suited for unloading or loading trucks, nor for moving loads quickly over long distances. Similar to the order selector, reach trucks could be available for lifting heights which are greater than 30 feet.
Rotating-Mast Trucks and Turret Trucks: Like regular sit-down forklifts, rotating mast trucks have masts that can rotate in one direction, to a 90 degree angle. This particular feature enables them to operate in a narrow aisle condition. Turret trucks could work in narrow or very narrow aisle places. Similar to order selectors, these machines could elevate both the operator and the cargo. Additionally, they can enable the operator to handle loads on either side of an aisle without re-entering and exiting the aisle.
Turret trucks are normally wire or rail guided when they are utilized within very narrow aisles. This way, the operator can focus on the work load at hand since they doesn't need to focus any energy on their driving skills. Since turret trucks are considered "operator-up" trucks, they can be used for picking items and cases in addition to full pallet handling.
