The competitiveness of China's construction machinery has rapidly improved

(Export engineering machinery is assembled at Yantai Port, Shandong Port, waiting for shipment.) Since December 1, excavators, loaders and other non road mobile machinery have switched from the "national third" emission standard to the "national fourth" emission standard, and green development has become a must for the construction machinery industry. Since 2022, enterprises in the construction machinery industry have taken precautions to seize the opportunity to switch emission standards, actively promoted transformation and upgrading, and made remarkable achievements in high-end and major equipment development, electrification and intelligent breakthroughs, as well as in improving international competitiveness. Promote technological innovation On July 26, 2022, the world's largest rotary drilling rig XR1600E was released in the new intelligent manufacturing base of XCMG Basic Engineering Machinery Co., Ltd. This product has successfully solved the construction problems of super large diameter and super deep piles in the complex environment of super large bridge projects, and will promote the efficient construction of "super projects". The relevant person in charge of XCMG Foundation said that after years of technical accumulation, the company has fully mastered the core technology in the field of infrastructure construction equipment, and has the most comprehensive super tonnage rotary drilling rig in the industry, and has achieved mass sales and application. Since entering 2022, China's construction machinery enterprises have always implemented the innovation driven development strategy, strengthened the close integration of production, teaching, research and application, put a batch of internationally advanced and leading engineering equipment on the market, and promoted and applied a batch of scientific research achievements and major technical equipment, which has better met the needs of national economic construction and major projects. "Continuously promote innovation, and China's construction machinery has been blooming and bearing fruit in recent two years." Lv Ying, deputy secretary-general of China Construction Machinery Industry Association, told reporters that not only a batch of high-end construction machinery and major technical equipment had been developed and applied, but also many equipment had achieved major breakthroughs in limiting parameters. Lv Ying introduced that, for example, an ultra small shield machine with a diameter of less than 3 meters has been successfully developed. Such a small volume needs to be equipped with many functional parts. Many problems need to be solved in terms of the integration of supporting parts and the lightweight of mechanism parts. For another example, the curb weight of truck cranes used to be about 60 tons, but now some of them have dropped to less than 50 tons, which can directly pass through some bridges and roads, and is expected to be used in more scenarios. Behind the improvement of overall performance and parameters is the improvement of the whole construction machinery industry chain. A number of domestic large backbone complete machine enterprises have continuously accelerated the localization process of parts and components, actively carried out high-end parts and components research and development, manufacturing, test and detection, and the localization rate of high-end parts and components has continued to increase. New progress has been made in the research and development of some key parts and components. A number of core component manufacturers have accelerated their deep integration with the industrial chain of complete machine enterprises. Some have moved from producing alternative products to the host supporting market, and some have entered the supporting supply system of high-end brand construction machinery manufacturers, achieving industrial upgrading. For the high-end exploration of the whole industry of construction machinery, CAS Member and Professor Youwei of Nanjing University said at the International Summit Forum on Innovation and Frontier Technology of China (Xuzhou) Construction Machinery Industry that the biggest difficulty of high-end construction machinery and its key components is the new materials that adapt to them. The upstream and downstream industrial chains of construction machinery should be innovated synergistically to accelerate the deep integration of "politics, industry, education, research, finance, and use" of new material industry, so as to achieve the goal as soon as possible
