附录 附录1 Chinas construction machinery and the development of the main achievements of crutches Abstract This paper a thorough review of Chinas construction machinery industry in the 50 years of the founding of the development process, On Chinas construction machinery industry achieved a major technological achievements, pointing out that the industrys technical level with the international advanced level in the gap and future construction machinery products in the development of technical characteristics. Keywords construction machinery technology development Construction of construction machinery is the main technical equipment, to ensure project quality, improve construction efficiency, speed up the progress of the project, reduce labor intensity of workers and guarantee of safety plays an important role. The founding of New China 50 years ago, especially after the Third Plenum of the 11th Party Congress, construction machinery and supporting the cause of building technology with Chinas rapid development has also made significant progress and achieved great achievements. 1 Development Since 1949, construction machinery industry from scratch, from small to large, experienced a start-up, industry formation and development of three high-speed development period: 1.1 Industry start-up period of In the early years of New China, the construction site of construction machinery are left over from old China Bolai Pin, China has not yet professional construction machinery factory. For the resumption of war suffered serious damage due to the national economy, to a large-scale economic construction upsurge in the demand in the mid-1950s, some of Chinas construction machinery repair workshop (plant) and other machinery factory gradually developed into a professional construction machinery built factory. In addition to the repair of construction machinery, began imitating foreign construction machinery, such as the alkaline-resistant Drum drum mixer, 2 ~
