[0002] In the construction process of building projects, tower cranes usually serve as key engineering equipment for vertical transportation during the construction of the main structure. Their selection and layout often have a significant impact on the efficient and safe construction of the project. In the construction of super-high-rise buildings, especially for super-high-rise buildings with a cylindrical structure, the use of internal climbing tower cranes has gradually become a preferred option due to its safety and economy. Internal climbing tower cranes are generally arranged in the core shaft or elevator shaft of super-high-rise buildings.
