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 disc valve industry plan, by 2015, the output value of 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. 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.

Su Zimeng said that during the 12th Five-Year Plan period, the construction machinery industry will focus on solving the problem of short boards for key components. He said that at present it is the best time to invest in the key components of construction machinery. The gate valve industry of our country’s construction machinery components has always been characterized by “the reluctance of large companies and small enterprises cannot do it”. In order to solve the current situation of parts and components, Xugong Machinery, Liugong, Zoomlion and other leading domestic construction machinery leading companies began to increase the intensity of parts and components research and development.

The key components of construction machinery are the foundation, support and restriction bottleneck of the development of engineering machinery products. After the development of the engineering ball valve to a certain stage, the industry's high-tech research focuses on key components such as engine, hydraulic, transmission and control technologies. Mastering and relying on high-quality, distinctive key components has become a strategy for manufacturers to seek "outstanding" strategies.
