In 2011, China's construction machinery industry sales revenue exceeded 500 billion yuan, ranking first in the world, an increase of 17% over the same period last year. In addition, China's construction machinery has met nearly 90% market demand in China. Although China's construction machinery industry has developed rapidly, it has an inexplicable pain: 70% of the profits are taken away by foreign enterprises because of the long-term dependence of key components on imports.
A few days ago, Long Guojian (the former chairman of the ZOOMLION board of supervisors and the former vice president of the Changsha Construction Machinery Research Institute), a national representative of the two meetings of the National Committee of the Chinese people's Political Consultative Conference (CPPCC), pointed out that the technical backwardness of the parts manufacturing technology in China's construction machinery industry should be solved by the three parties of the government, the host plant and the supporting enterprise.
Spare parts depend on import
Most of the profits are made to foreign businessmen
At present, most of the key parts of the construction machinery industry in China need to be imported from abroad, which leads to high production cost and lack of international competitiveness, especially for excavator products, and the import of parts is expensive, and 70% of the profits are "eaten" by foreign enterprises. Spare parts have become a stumbling block on the way forward for Chinese construction machinery manufacturers.
According to statistics of Hunan Machinery Industry Association, the cost of parts and components accounts for about 40% of the manufacturing cost of the main engine products produced by construction machinery enterprises above the provincial scale. On the premise of such a premise, in order to expand the market, all the major engineering machinery manufacturers generally take the way of selling on credit. Once the market market is not good, a large amount of surplus money is bound to cause bad debts.
The statistical data of the import and export summary of China's construction machinery products in 2009 shows that in the total total import ($5 billion 147 million 817 thousand and 800) in 2009, the capital of parts and components was ranked first, with a total of 1 billion 835 million 386 thousand and 400 dollars, which accounted for up to 36%. In the first half of 2011, the total import and export of construction machinery spare parts in China amounted to US $4 billion 488 million, of which the import volume was US $2 billion 128 million. China's construction machinery industry has fallen into a strange circle of low-end competition and high-end missing, and most of the profits of the construction machinery manufacturers have been seized by foreign businessmen.
Policy support of the state
Joint participation of upstream and downstream enterprises
Long Guo Jian stressed that to solve the backward problem of spare parts manufacturing technology requires joint efforts of upstream and downstream enterprises, which is estimated to take a long time. The government should guide the relevant policies to enhance the motivation of the enterprise's innovation and development; the enterprises should strengthen their own competitiveness, learn from the foreign outstanding host manufacturers and supporting enterprises, and gradually narrow the gap.
It is understood that the technical backwardness of the core parts and spare parts in China's engineering machinery industry has aroused great attention from the state. From the "adjustment and revitalization of the equipment manufacturing industry" issued in 2009 and the implementation plan for the revitalization of the machinery base parts industry in 2010, and then to the machinery basic parts and basic systems issued in 2011. The "12th Five-Year" development plan for manufacturing technology and basic materials industry is becoming more and more targeted.
In recent years, under the condition that the domestic professional accessories are not mature, a few powerful engineering machinery production enterprises have begun to develop the core hydraulic components of the excavators, such as the leading domestic engineering machinery enterprises, such as Xugong Group, Sany, ZOOMLION and other well-known engineering machinery leading enterprises, have increased the input force to the research and development of parts and components. Degree.
15 years behind the manufacturing technology of parts and components
"12th Five-Year" will focus on the attack
China's construction machinery parts and components technology is low, unable to enter the mainstream market of key components. Compared with international advanced products, the manufacturing technology of basic parts of construction machinery in China is behind 15 years. Long Guojian believes that it is imperative to solve the backward problem of spare parts manufacturing technology.
The dynamic performance of the engineering machinery is the most important index to measure the technical level of the product, including the two parts of the dynamic performance of the diesel engine and the comprehensive performance of the power transmission of the whole machine. The engineering technology of construction machinery mainly includes common technologies such as constantly improving fuel injection system and reducing fuel consumption. In addition, torque reserve and power output modes, performance matching, vibration and noise technologies at low speeds are also very important. At present, the commonly used auxiliary engines in China's construction machinery products are mainly foreign brands such as Cummings, doez, Pt, suzu and Yanmar. The domestic engine brands are mainly Weichai and Chai. Almost all of the supporting engines used for high-end products, export equipment, large tonnage equipment and excavators are foreign brands.
In July 31, 2011, China's construction machinery industry "12th Five-Year" development plan was released. The plan is clear, will focus on improving the technical level and manufacturing level of the key parts of the engineering machinery, and emphasizes three aspects: one is to strengthen the dynamic matching performance of the engineering machinery products, and the two is to develop the product of the hydraulic components of the engineering machinery and the high precision and scale manufacturing, and three to the special transmission parts. Systematic research on sex and durability.
China Construction Machinery Industry Association, standing vice president and Secretary General Su Zimeng, said that during the "12th Five-Year", China's construction machinery industry will focus on the problem of the backward manufacturing technology of key components.
