Technical Field
[0001] This utility model relates to the technical field of tower crane attachment and cantilever systems, and in particular to a telescopic adjustable tower crane attachment and cantilever system. Background Technology
[0002] When tower cranes are used in bridge or building construction with small cross-sections, the attachment angle cannot meet the requirements due to the small structural cross-section, so a cantilever system is needed to meet the attachment requirements.
[0003] The existing cantilever system dimensions are based on on-site fabrication of members. Because bridge structural sections typically shrink, the cantilever system dimensions need to be re-fabricated each time it is used in another project. Each modification results in wear and tear, and both modification and re-fabrication consume significant manpower and materials, leading to poor economic efficiency. Ultimately, this results in the following problems:
[0004] First, existing cantilever systems need to be remanufactured due to structural shrinkage, which greatly affects the safety and economy of tower crane cantilever system applications. Second, existing cantilever systems cannot be mass-produced and transported, increasing production and transportation costs, and on-site installation is not convenient enough. Therefore, it is necessary to design a telescopic and adjustable tower crane attachment cantilever system. Utility Model Content
