In the related scheme, the upright column of the roadway stacker is generally of a single-section structure, and the height of the single-section upright column is generally higher. Due to the limitation of the height of a stacker manufacturing factory building and the influence of scattered structural layout of parts, the parts cannot be preassembled before leaving the factory. The automatic stereoscopic warehouse project site can meet the installation requirements, and the installation of the stacker parts can be only carried out on the automatic stereoscopic warehouse project site.

The chassis, the upright post, the electric control cabinet, the lifting driving mechanism and the cargo carrying platform need to be installed on site in sequence, the installation process is complex, and multiple times of high-altitude operation are involved. Because preassembling is not carried out before leaving the factory, more transportation space is occupied during loading transportation, a plurality of assembly problems are exposed and discovered during project field assembly, and the time is consumed in the process of modification.

In addition, the axial direction of the winding drums is perpendicular to the advancing direction of the tunnel type stacker, namely the winding drums are transversely arranged, so that the tunnel type stacker is large in transverse size and can advance only by the aid of the wide tunnel width. The wider roadway width occupies a larger warehouse space, and the available space of a goods shelf area in the warehouse is occupied by extrusion.
