Narrow Aisle Lift Trucks
Narrow Aisle Lift Trucks are electric trucks designed to operate in narrow aisles. A counterbalanced lift truck could turn in the aisle since typical storage aisles are only 3.6 meters wide and this is enough space. On the other hand, narrow aisles can be 2.4 meters wide to as little as 1.8 meters. The narrow space needs specific lift truck models that are small, capable of tight turns, and able to put away loads without pivoting. The popular kinds 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 can easily turn in narrow aisles as their design has eliminated the requirement for a big counterweight. Stability is instead provided by outrigger arms which extend in front of the truck. The downside of this particular design is that the outrigger arms can inhibit access to the storage rack as the truck cannot get near enough. These types of trucks work well within a warehouse which is well lit, has even, clean floors, ample turning space and good traffic flow.
Turret trucks
The design of a turret truck consists of forks on the side that pivot. The forks pivot 90 degrees and move from side to side. The load faces forward while the operator drives down the aisle. When it stops at the designated storage place, the truck's forks pivot to the storage side and raise the load to their full extension, and then easily 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.
