The key parts of construction machinery have become bigger or have been supported by domestic enterprises.

The reporter learned from the China Construction Machinery Industry Association on November 29 that two sets of key components supporting policies for construction machinery have been reported to the Ministry of Industry and Information Technology. According to reports, the two support programs will use 20 megapascals as the boundary, and parts with and above 20 megapascals will adopt different support policies. (Note: megapascal refers to the working pressure that the engineering machinery parts can bear.) If this scheme is passed, it will not only help accelerate the localization of key components, but will also vigorously promote the development of the energy equipment industry.

Developing key components into important strategies

Su Zimeng, secretary general of the China Construction Machinery Industry Association, said that in the next five years, China's construction machinery industry will take the structural adjustment and development approach as the main line and implement the strategy of “adjustment of transformation, innovation and upgrading”. The development of key components is a major component of the strategy.

Prior to this, the Implementation Plan for the Revitalization of Machinery Basic Components Industry issued by the Ministry of Industry and Information Technology clearly stated that it is necessary to accelerate the breakthrough in the development of bottlenecks in key parts and components and continue to meet the needs of equipment and strategic emerging industries in various fields. Through three years of hard work, the manufacturing level of our country's mechanical basic parts and components has been significantly improved, the capability of independent innovation has been greatly improved, the situation of unreasonable industrial structure has been improved, and the passive situation in which the development of basic parts and components industries is seriously lagging behind has gradually been reversed.

China's construction machinery industry has achieved rapid development in the past 10 years. In 2010, the industry's output value is expected to exceed 400 billion yuan. According to the industry plan, by 2015, the conservative estimate of the output value of the construction machinery industry will exceed 900 billion yuan. In spite of this, the further development of China's construction machinery industry is subject to key components. The basic components can not meet the requirements of the host supporting, has become a bottleneck restricting the development of China's major equipment. At present, most of the key components, including hydraulic components and transmission systems, need to be imported from abroad. This has led to high production costs for domestic machine manufacturers and lack of international competitiveness.

Parts are becoming bigger and bigger in domestic companies

Wang Xiaolin, a researcher at Beijing Jiahua Consultant Co., Ltd., told the reporter that since the 1990s, the construction machinery manufacturing industry has presented two major development trends: First, cross-border M&A and joint development have accelerated; second, the specialized production of components and global procurement. Wang Xiaolin believes that it may not be surprising for a single company to independently purchase key components. However, for the entire industry, the key components cannot be self-sufficient, and they will undoubtedly lose the right to speak in the market and take the initiative in development. “Made in China” will This is "Chinese assembly".

According to report, Xugong Group, a leading enterprise in China's machinery industry, has obvious advantages in hosting, but many parts and components in export products still rely on imports. "Because the domestic construction machinery industry does not possess the core technology of key components, the cost of spare parts accounts for about 30% of the export price."

According to the Sany Heavy Industry technicians, compared with the international advanced level, the average gap in the technical level of construction machinery products in China is about 15 years, mainly reflected in the product reliability, overall life, appearance quality and information technology level. These gaps are reflected in the basic component technology level.

A responsible person of Zoomlion also revealed that in order to obtain relevant parts and components, some companies had to send special procurement personnel and waited at the factories of foreign suppliers; some companies often transported raw materials to reduce losses due to missed work. The cost has risen sharply; other companies have had difficulty in completing order production due to the lack of related parts and components and have had to re-adjust production schedules and plans.

The reporter learned from the China Construction Machinery Industry Association that China's construction machinery parts and components manufacturing enterprises have grown to more than a thousand, but most of the products have low technological content and cannot enter the mainstream market for key components. The key components of high-end technology products for construction machinery come from international companies. Since the financial crisis, due to the rise of trade protectionism, the control of these companies on the supporting needs of Chinese host manufacturing companies has become a constraint factor in the development of China's construction machinery industry.

It is understood that there are two main reasons for the low technical level of parts and components in the domestic construction machinery industry: First, component manufacturers are mainly small and medium-sized enterprises, and lack enterprise groups with independent intellectual property rights, prominent main businesses, and strong core competitiveness. Second, each main engine manufacturer pays insufficient attention to the R&D of supporting parts and components, and most of the enterprises focus on host development and production.

Leading companies may establish technology alliances

According to Mao Zhongwen, deputy secretary-general of the China Construction Machinery Industry Association, the biggest gap between China's spare parts companies and internationally renowned companies lies in basic technology, R&D personnel, experimental methods, and corporate development concepts. Internationally renowned companies can not only master the matching requirements with the host products in the product development stage, but also invest a lot of funds for each new product development, and carry out hundreds of thousands of times to millions of assessment tests, in terms of product reliability. Fine management and production. On the contrary, domestic enterprises are all model-based operations, lack of technical theoretical research, lack of research on front-end technologies such as raw materials and roughs, and lack of matching test assessment methods, so this gap is not an order of magnitude.

Wang Xiaolin suggested that local host companies and supporting enterprises should establish long-term strategic partnerships. From the host enterprise group to the basic parts and components companies to invest funds and technical support to enhance the supporting enterprise production capacity. Under the guidance and support of policies, several large-scale basic component enterprise groups have been established through asset reorganization or mergers and acquisitions to enhance market development and new product research and development capabilities.

It is reported that at present, Xugong, Liugong, Zoomlion and other leading domestic construction machinery leading companies have begun to increase the intensity of component research and development. Industrial organizations such as the Construction Machinery Industry Association also intends to let several major machine companies take the lead in forming technology alliances to carry out technical research on key components.

In addition, the support of the national competent authorities for parts and components has recently increased significantly. According to the latest documents from the Ministry of Industry and Information Technology, wind turbine generator bearings, generator bearings and main shaft bearings, gear transmissions for wind turbines of 1.5 MW or more, hydraulic servo systems and sealing systems for yaw and pitch change, and wind turbine towers Specifications High-strength Fasteners, Blade Forming Dies, Large precision stamping dies for motor stator and rotor parts, Large-scale hydro-generator ball valves, Runner blades, Servo-membrance sealing systems; Secondary pump bearings for nuclear power plants, New nuclear power main pump tertiary sealing devices High-reliability fasteners for nuclear power, etc. will be supported in the future.
