Abstract: This paper briefly analyzes the development of prefabricated construction and construction machinery,and summarizes the influence of prefabricated construction on the development of construction machinery.On this basis, from the aspects of forming a new mode of "manufacturing + building", promoting the R & D and production of a new generation of high-end tower crane, transforming tower crane leasing into a "new trend",and the application of a complete set of intelligent equipment for prefabricated buildings, this paper expounds the integration development trend of construction machinery and prefabricated buildings, for reference.
