Narrow Aisle Lift Trucks
The type of electric truck which is designed to operate in narrow aisles is called a Narrow Aisle Lift Truck. A counterbalanced lift truck could turn within the aisle since typical storage aisles are only 3.6 meters wide and this is adequate space. Nonetheless, narrow aisles could be around 2.4 meters wide to as little as 1.8 meters. The narrow area needs specific lift truck models that are small, capable of tight turns, and able to put away loads without pivoting. The common types of narrow-aisle trucks are reach trucks, turret trucks and orderpickers.
Narrow-aisle reach trucks
Reach trucks were the first narrow-aisle lift truck to be manufactured for warehouse use. These small trucks could turn with no trouble in narrow aisles because their design has eliminated the requirement for a big counterweight. Instead, stability is provided by outrigger arms extending in front of the truck. The downside of this particular design is that the outrigger arms could hinder access to the storage rack as the truck cannot get close enough. These trucks work well inside a warehouse which is well lit, has even, clean floors, ample turning space and good flow of traffic.
Turret trucks
The design of a turret truck has turning forks on side of the truck. The forks pivot 90 degrees and move from side to side. The load can face forward whilst the operator drives down the aisle. When it stops at the designated storage location, the truck's forks pivot to the storage side and lift the load to their full extension, and next smoothly deposit the load before resuming their original position. Turret trucks are available with a wire guidance system which keeps the truck on its path in really narrow aisles. Operators remain at floor level in man-down trucks.
