Construction Machinery continues to strengthen the pace of transformation and upgrading

In the past ten years, the construction machinery market in China has developed rapidly at an alarming rate. This decade has been hailed as a "golden decade" for construction machinery by the people of the country. The total industrial output value of China has increased from 1.69 trillion yuan in 2001 to 14.38 trillion yuan in 2010, with an average annual growth rate of 23.86%. In 2009, China’s machinery industry sold more than US$1.5 trillion in sales, surpassing Japan and the United States to become the world’s largest manufacturer of machinery. However, China is a big country of construction machinery but not a country with strong engineering machinery. Its basic raw materials, core parts and components, and key technologies are controlled by people. 70% of its profits are swallowed up by imported infrastructure. The transformation and upgrading of equipment manufacturing industry is the only way for development. With the increase in production and operating costs, difficulty in exporting, difficulty in eliminating overcapacity pressures, and increasingly fierce internal competition, construction machinery companies have begun to increase their service and scientific research and rely on autonomy in a situation where the market environment is not favorable. Innovation advances to high-end product upgrades.

At present, the R&D input of 204 listed companies in the machinery industry in China accounts for only about 2% of the total income. Compared with the 6% of the 245 listed companies in the US, the R&D expenditure of China's machinery industry is obviously insufficient. From the experience of industrial development in developed countries, companies with significantly higher R&D investment have substantially improved their operating performance and profitability over the next 5-10 years. At the same time, these listed companies’ excess returns on their stocks are less than R&D investment. The company is much higher.

In order to improve the weak links in product technology and increase the added value of products, the investment in science and technology by enterprises in the construction machinery industry continues to increase, and scientific research forces continue to strengthen. For example, after the founding of Jiangsu Xuzhou Construction Machinery Research Institute, with the support of Jiangsu Science and Technology Department and the Ministry of Finance and the active efforts of Xugong Group, the company focused on building a world-class engineering machinery research and development institution; Hongxing Machinery's national concrete mechanical engineering technology was established last year. The research center has made new progress in various scientific and technological innovations this year; Liugong shares have been approved by the Ministry of Science and Technology this year as the only national engineering and technology research center for earth-moving machinery industry. This is the research, development, technological innovation and industrialization of the earth-moving machinery industry in China. The demonstration of an important base represents the first-class level of technological development and transformation of achievements in the earth-moving machinery industry in China. The Komatsu Product Technology Development Center, a world-class construction machinery product technology development center invested and established by Komatsu, was opened in Changzhou.

The current per capita output of China's equipment manufacturing industry is low, resource consumption is large, sustainability is insufficient, and technology upgrading is imperative. In the future, R&D and upgrading of construction machinery technology, the core components, energy-saving emission reduction and intelligent equipment manufacturing will become three bright stars, illuminating the road ahead for the technological development of China's construction machinery industry.

Increase in the level of equipment manufacturing industry It is understood that the current size of the equipment manufacturing industry in the United States and Japan is 1.5 trillion US dollars and 1.2 trillion US dollars, although the size of China's equipment manufacturing industry has exceeded the 2 trillion US dollars mark, ranking first in the world. However, the issue of “big” rather than “strong” industries is very prominent. For example, in the field of high-end equipment, key technologies and equipment such as 80% of integrated circuit chip manufacturing equipment, 70% of key equipment for automobile manufacturing, and 40% of large-scale petrochemical equipment still need to rely on imports. The products produced lack core competitiveness. Moreover, with the rapid rise in raw material prices and labor costs, SMEs are under tremendous pressure and it is urgent to transform the traditional equipment manufacturing industry. Steam dryers and cement production equipment as intelligent equipment for the pyramid manufacturing industry have played a pivotal role in the overall level of China's equipment manufacturing industry. Zhang Xiangmu, director of the Department of Equipment Industry at the Ministry of Industry and Information Technology, said: "The development of intelligent manufacturing equipment is a requirement for the transformation and upgrading of traditional industries and the development of strategic emerging industries." As the smart equipment with the greatest potential for development in the equipment manufacturing industry, it will become an advancing country in China. The equipment manufacturing industry is heading towards the "precision" of the most important forces.

Experts pointed out that under the support of the National Twelfth Five-Year Plan for Major Tackling Key Projects and National Major Scientific and Technological Projects, China has achieved a number of breakthrough achievements in smart manufacturing equipment in recent years. Such as large-scale, heavy-duty, extreme manufacturing equipment and CNC machine tools, as well as some basic functional components, CNC systems, cutting tools and cutting technology, the gap between China and foreign advanced technology is gradually shortening.

Yang Xujing, deputy director of the School of Mechanical and Vehicle Engineering at Hunan University, believes that the current national policies for the smart manufacturing equipment industry will increase the level of equipment manufacturing from intelligent, precision, green, and integration to high-end markets. .

Breakthrough in core component technology For a long time, the core technology of components has always been a heart disease in China's construction machinery industry. After years of efforts, the domestic average market share of domestic machinery parts such as bearings, gears, and fasteners has reached 65%. The low-end and middle-end products can basically be resolved independently, but high-end products still rely on imports. The rapid development of high-end hosts has made the contradiction between the high-end "three-base" products not matched with the host's supporting needs to become more prominent and has become a bottleneck restricting the development of China's major equipment and high-end equipment.

At the end of November 2011, the Ministry of Industry and Information Technology formally issued the “12th Five-Year Development Plan for Machinery Basic Parts, Basic Manufacturing Processes and Basic Materials Industry”. Mechanical basic parts, basic manufacturing processes and basic materials are the basis for the survival and development of the equipment manufacturing industry, and their level directly determines the performance, quality and reliability of major equipment and host products. The promulgation of the "Three-based" plan has become a major event in the equipment manufacturing industry this year, boosting confidence in the industry. Leading enterprises in the equipment manufacturing industry, such as Sany Heavy Industry, Xugong Group, and Liugong Group, began to invest heavily in capital and scientific research, and actively carried out research and development of basic components and parts, and achieved remarkable results. Data show that from January to November this year, the domestic production of hydraulic components reached 186 million, an increase of 61.05%. At the same time, China's critical basic component research has made new breakthroughs in various fields. The process of localization of high-end hydraulic parts has dawned; high-end pressure transducer technology involving automation instrumentation industry has made substantial progress; UHV AC and DC insulation bushings and transformer outlets, natural gas pipelines and large thermal and nuclear power equipment valves, nuclear power The high-end seals used in the device also have a great breakthrough.
