Narrow Aisle Lift Trucks
Narrow Aisle Lift Trucks are electric trucks made to function within narrow aisles. A counterbalanced lift truck could turn in the aisle since typical storage aisles are only 3.6 meters wide and this is sufficient space. Nonetheless, narrow aisles can be 2.4 meters wide to as little as 1.8 meters. The narrow area requires specialized lift truck models which are small, capable of tight turns, and able to put away loads without pivoting. The popular types of narrow-aisle trucks are turret trucks, order pickers and reach trucks.
Narrow-aisle reach trucks
The first types of narrow-aisle lift trucks manufactured for warehouse applications are the reach trucks. These small trucks can turn without problems in narrow aisles as their design has eliminated the requirement for a large counterweight. Instead, stability is provided by outrigger arms which extend in front of the truck. The disadvantage of this design is that the outrigger arms can hinder access to the storage rack since the truck cannot get close enough. These trucks truly work well within a warehouse which is well lit, has even, clean floors, ample space for turning and good traffic flow.
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 could face forward while the operator drives down the aisle. Once stopped at the designated storage place, the forks of the truck pivot 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 can 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.
