Aisle stacker cranes have evolved from forklift trucks and bridge stacker cranes. The bridge type stacker cranes are very limited in running speed due to the heavy bridge, and they are only suitable for warehouses that do not have a high access frequency or store long raw materials and bulky goods. The main purpose of the aisle stacker is to shuttle back and forth in the aisle of the high-level racking to deposit the goods located at the entrance of the aisle into the goods compartment; or, take out the goods in the goods compartment and transport them to the entrance of the aisle.

Single column type aisle stacker:

1. The frame structure is a rectangular frame composed of 1 column, upper crossbeam and lower crossbeam

2. Structural rigidity is worse than double column.

Suitable for warehouses with a lifting capacity of less than 2 tons and a lifting height of less than 16 meters.
