Narrow Aisle Lift Trucks
Narrow Aisle Lift Trucks are electric trucks made to operate within narrow aisles. Standard storage aisles are only 3.6 meters wide, adequate space for a counterbalanced lift truck to turn in the aisle. Nevertheless, narrow aisles could be about 2.4 meters wide to as little as 1.8 meters. The narrow space requires specialized lift truck models which are small, capable of tight turns, can put away loads without turning. The popular types of narrow-aisle trucks are turret trucks, order pickers and reach trucks.
Narrow-aisle reach trucks
Reach trucks were the very first narrow-aisle lift truck to be manufactured for warehouse use. These small trucks could easily turn in narrow aisles as their design has eliminated the requirement for a huge counterweight. Stability is instead provided by outrigger arms that extend in front of the truck. The downside of this design is that the outrigger arms can inhibit access to the storage rack because the truck cannot get close enough. These kinds of trucks work well inside a warehouse that is well lit, has clean, even floors, good flow of traffic and enough space for turning.
Turret trucks
The turret truck design includes forks on the side which turn. The forks pivot 90 degrees and move from side to side. The load can face forward whilst the operator drives down the aisle. When stopped at the designated storage place, the forks of the truck pivot to the storage side and lift the load to their full extension, and then smoothly deposit the load before resuming their original position. Turret trucks could come with a wire guidance system that keeps the truck on its path in really narrow aisles. In man-down trucks, operators remain at floor level.
