[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. An elevator shaft is the shaft through which the elevator is installed. The size of the shaft is determined according to the elevator model. Elevator tracks and counterweight tracks are installed on the shaft walls, and elevator doors are installed in the reserved door openings. The elevator machine room is located at the top of the shaft.

[0003] The overall load-bearing capacity of a steel elevator shaft is achieved through a supporting steel frame.

Currently, regular maintenance and inspection of elevator shafts are essential to ensure their safe operation. However, manual inspection has many drawbacks: it is inefficient, unable to meet the demands of frequent elevator shaft maintenance, often fails to promptly identify potential safety hazards, and maintenance personnel must work within the narrow, complex, and elevated spaces of the elevator shaft, facing risks such as falls from heights, electric shock, and oxygen deprivation, making effective safety assurance difficult.
