Narrow Aisle Lift Trucks
Narrow Aisle Lift Trucks are electric trucks designed 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. However, narrow aisles can be about 2.4 meters wide to as little as 1.8 meters. The narrow space requires specific kinds of lift trucks that are capable of tight turns, small, can put away loads without turning. The popular kinds of narrow-aisle trucks are turret trucks, order pickers and reach trucks.
Narrow-aisle reach trucks
Reach trucks were the first narrow-aisle lift truck to be manufactured for warehouse applications. These small trucks can turn without difficulty in narrow aisles as their design has eliminated the requirement for a big counterweight. Stability is instead provided by outrigger arms that extend in front of the truck. The disadvantage of this design is that the outrigger arms could inhibit access to the storage rack as the truck cannot get near enough. These trucks work well inside a warehouse that is well lit, has even, clean floors, enough space for turning and good flow of traffic.
Turret trucks
The turret truck design has turning forks on side of the truck. The forks pivot 90 degrees and move from side to side. The load faces forward whilst the operator drives down the aisle. When it stops at the designated storage location, the truck's forks turn to the storage side and raise the load to their full extension, and next easily deposit the load prior to 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.
