[0012] This utility model achieves the following beneficial effects:

[0013] The freight elevator frame provided in this application, through scientific and reasonable structural design and 3D modeling stress analysis, has been continuously improved and optimized. This not only simplifies the frame structure and reduces the production, transportation, and installation costs of the entire elevator, but also improves the overall load-bearing capacity and resistance to torsion and tilting of the frame structure.
