Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Steel structure columns and beams need to be straightened with straightening equipment when in use.

[0003] For example, Chinese patent publication number CN221209458U discloses a straightening device for steel structure columns and beams, including a working platform, the bottom of which is fixedly connected to a support.
