in order to give full play to the performance of existing mechanized construction equipment and further improve the efficiency of mechanized construction, this paper analyzes the coincidence degree between the structural parameters of typical tower and the lifting performance of truck crane, and puts forward the optimization principle of integrated design of tower structure and equipment. Based on this principle, the optimal adjustment of the tower structure of sublevel height and crane, connection type design of tower component disconnection, compares the matching degree before and after optimization of tower structure parameters and equipment lifting capacity. Finally, the tower structure parameter optimization based on the quantification of the efficiency and effectiveness of the new tower structure of mechanical construction, analysis and comparison of the integration design before and after the mechanical construction of the key indicators, the results show that the integrated design of tower structure, more conducive to the construction of equipment performance, reduce the operation times and high lifting installation bolt the fastening workload, greatly reduces the work efficiency significantly improved, high-altitude operation risk, safety and quality benefits.
