INSTALLATION AND OPERATION OF TOWER CRANE GROUP IN LARGE PUBLIC BUILDING PROJECT

The National Conference Center Project is characterized by complicated structure,large floor area,steel and concrete composite structure,heavy single steel members,large amount of formwork and big building height and etc.Therefore the distribution and operation of tower cranes during structural construction are directly related to the safety,quality and schedule of the project.11 tower cranes were used in the structural construction,with most of crane arms intercrossed.In order to ensure safe operation,management measures were taken in the construction,including strict control of height differences of the crane group,rational lifting order of tower bodies,reasonable design of tower crane space and emphasis on the safety management of operation and etc,all of which have guaranteed the construction of the project.
