Technical Field

[0001] The present application relates to the technical field of hoisting equipment, and in particular to a steel structure hoisting equipment. Background Art

[0002] Steel structure is a profile that is often used in current construction projects and is one of the more common structural forms in modern construction projects. The profile of steel structure is light in weight and high in strength, and is suitable for a variety of construction projects. Steel structure profiles often need to be transported on construction sites, usually using lifting equipment to transport steel structures.

[0003] However, traditional lifting equipment usually uses ropes for hanging and lifting when lifting steel structures. The steel needs to be kept balanced during the hanging and lifting process. Therefore, it is necessary to accurately find the center point of the steel structure first to prevent it from tilting and falling during the lifting process. This process not only requires a lot of preliminary preparation work, but is also not convenient to use. In addition, the ropes are easily affected by factors such as impact, friction and wear of objects during the lifting process, which may cause damage to the ropes.
