Narrow Aisle Lift Trucks
Narrow Aisle Lift Trucks are electric trucks designed to function in narrow aisles. A counterbalanced lift truck could turn in the aisle since standard storage aisles are just 3.6 meters wide and this is sufficient space. Then again, narrow aisles could be 2.4 meters wide to as little as 1.8 meters. The narrow space requires specialized kinds of lift trucks 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
The very first types of narrow-aisle lift trucks manufactured for warehouse applications are the reach trucks. These small trucks can turn without problems within narrow aisles since 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 close enough. These kinds of trucks work well within a warehouse which is well lit, has even, clean floors, good traffic flow and ample space for turning.
Turret trucks
The design of a turret truck has pivoting 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 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 very narrow aisles. Operators remain at floor level in man-down trucks.
