Based on Xi’an Silk Road Happy World Landmark Tower project, the key technical problemsin the installation process of tower crane for high⁃rise steel structure are discussed. By analyzing thecharacteristics of the engineering structure, the reasonable equipment selection and hoisting scheme aredetermined, and the wall attached installation of ZSL750X⁃50t boom tower crane is mainly studied. Thefinite element model is used to simulate and check the mechanical performance of the main steel structureand tower crane under wind load, which verifies the construction safety, and the targeted reinforcementscheme is put forward. The research results show that when the tower crane attachment part is a cylinder,the arc wall attachment welding connection and U⁃shaped end plate separation connection can effectivelyimprove the stability and installation accuracy of the tower crane attachment wall.
