[0002] In order to make the building more beautiful, many steel structure buildings will be equipped with cantilever structures. However, as the building age increases, the safety of the cantilever structure will decrease. At this time, in order to ensure the safety of the main structure of the building, the cantilever structure needs to be dismantled and reconstructed. In the dismantling and reconstruction of the cantilever structure, the removal of the cantilever beam, especially the cantilever arc beam (designed according to the cantilever structure) is a very important process. In conventional demolition construction, the removal of the cantilever beam is basically achieved in conjunction with the tower crane.
