The core components of engineering machinery cannot be controlled by people for a long time

It is an indisputable fact that China is a big manufacturing country. The sales revenue of construction machinery industry in China exceeded 500 billion yuan, an increase of over 17% year-on-year. Not only has the industry's production and sales volume ranked first in the world, it has also met nearly 90% of China's domestic market demand. However, behind the high-speed development of the construction machinery industry, there are hardships. The core parts and components of the construction machinery industry have long relied on imports. It is reported that key parts are highly profitable, and China’s construction machinery companies can only give this cake to people because of their immaturity. Especially the lack of high-end hydraulic components of construction machinery has become the “painful throat” of the construction machinery industry.

“China’s current hydraulic components used in excavators over 20 tons are basically controlled by a company, which is the Japanese Kawasaki Company.” Every time he talks about this matter, Sha Baosen is full of expressions. In March 2011, the earthquake in Japan. Thousands of miles away from the east-west earthquake, but also affected the domestic excavator manufacturers. From March to April 2011, the supply of Japanese excavator hydraulic components was interrupted, and the domestic excavator OEMs that mainly depended on the hydraulic components imported from Japan were forced to slow down the production pace, and some could only stop work. Since Japan’s Kawasaki Corporation’s principle of supply in the event of an emergency is first domestic and then foreign, some Chinese OEMs have to find sources everywhere in order not to affect the progress of production. In particular, those excavator plants that have just been launched in the new round of capacity expansion are not satisfied with their supply requirements because they are not regular customers of Kawasaki. The extent of reliance on foreign imported hydraulic components in China's excavator industry is generally visible. “You’re welcome to say that China’s current mainframe vendors are like Kawasaki’s one after another sales agent. The rapid development of China’s construction machinery has brought a huge market to Kawasaki. Many Chinese companies are currently playing the role of part assembly plants. , The level of technology is low, the accumulation is low, and development is worrying.” Some industry experts say so. Japan's earthquake has brought a huge market gap to China's hydraulic components. China’s market share has quickly been occupied by companies such as Dr. Rexroth and South Korea’s Dongming. In addition, the automotive chassis of the construction machinery industry is highly dependent on imports, and the manufacturing technology of the core components of construction machinery is in urgent need of breakthrough.

Due to the rapid development of construction machinery industry. The market for hydraulic components is promising. According to incomplete statistics, in 2011 China's liquid and airtight industries achieved a total industrial output value of 77.271 billion yuan, an increase of 21%. The hydraulic industry completed 43.62 billion yuan, an increase of 18.47%; the pneumatic industry completed 15.046 billion yuan, an increase of 29.60%; sealed industry completed 18.605 billion yuan, an increase of 23.95%. Of the 125 key contact enterprises in the liquid airtight industry, 64 were in the hydraulic industry, 6 in the hydraulics industry, 40 in the pneumatic industry, and 15 in the sealing industry. The comprehensive index of economic efficiency was 233.56, which was more than 226.44 in the same period of last year. The total industrial output value of these key linking enterprises was 33.424 billion yuan, an increase of 12.94% over the same period of last year. The output value of the hydraulic enterprise was 14.171 billion yuan, an increase of 7.72% over the same period of last year. The output value of the hydraulic enterprise was 533 million yuan, down 4.77% year-on-year; the output value of the pneumatic enterprise was 8.639 billion yuan, an increase of 25.12% over the previous year; the output value of the sealed enterprise was 7.320 billion yuan. 11.14% growth.

The development prospects of the liquid gas tight industry have also attracted a lot of investment both inside and outside the industry. According to incomplete statistics, in the last two years, the investment in the liquid gas-tight industry was not less than 30 billion yuan, of which the investment in hydraulics for construction machinery and other host industries accounted for about 50% of the total investment. Many well-known construction machinery companies, such as Sany Heavy Industry, Liugong, Longgong, Zoomlion, and Shandong Changlin, have invested or merged and restructured hydraulic companies.

It is believed that the attention of the state, the intervention of leading enterprises in construction machinery, and the parts and components of construction machinery will surely break the technological bottleneck and realize the goal of making China in China.
