[0012] A further improvement of the present utility model is that a part of the horizontal connecting plate is connected to the support beam by bolts, and the remaining part is connected to the intermediate beam by bolts.

[0018] A hoist is adopted under the hanging bracket body of the present utility model, reducing the potential safety hazards caused by the inclination during the hoisting process due to different center of gravity of the box body.
