Narrow Aisle Lift Trucks
Narrow Aisle Lift Trucks are electric trucks designed to function in narrow aisles. A counterbalanced lift truck could turn within the aisle because standard storage aisles are just 3.6 meters wide and this is adequate space. However, narrow aisles could be 2.4 meters wide to as little as 1.8 meters. The narrow space requires specific lift truck models which are small, capable of tight turns, can put away loads without pivoting. The popular types of narrow-aisle trucks are reach trucks, turret trucks and orderpickers.
Narrow-aisle reach trucks
Reach trucks were the very first narrow-aisle lift truck to be developed for warehouse applications. These small trucks can easily turn within narrow aisles because their design has eliminated the need for a huge counterweight. Instead, stability is provided by outrigger arms extending in front of the truck. The downside of this design is that the outrigger arms could hinder access to the storage rack since the truck cannot get close enough. These kinds of trucks work well in a warehouse which is well lit, has clean, even floors, good traffic flow and ample turning space.
Turret trucks
The turret truck design includes forks on the side which pivot. The forks turn 90 degrees and move from side to side. The load faces forward while the operator drives down the aisle. Once stopped at the designated storage location, the truck's forks pivot to the storage side and raise the load to their full extension, and then smoothly deposit the load prior to resuming their original position. Turret trucks are available with a wire guidance system that keeps the truck on its path in really narrow aisles. Operators remain at floor level in man-down trucks.
