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.

Double column type aisle stacker:

1. The frame structure is a rectangular frame composed of 2 columns, upper crossbeam and lower crossbeam

2. Structural rigidity is better

3. Larger mass than single column

Suitable for warehouses with various lifting heights, general lifting capacity up to 5 tons, or larger if necessary, can be used for high-speed running
