| Abstract: | In All China Federation of Trade Unions China Worker＇s Centre for International Exchange project, construction scheme is optimized with consideration of limited construction site and inconvenient operation of heavy auto-crane. During construction of two-way large-span steel structure cross beam, different methods are adopted, such as segmented lifting within effective lifting radius, floor assembly, integral floor slippage, capstan plus pulley block integral lifting, to effective reduce the construction cost and to improve the construction safety. |
