[0003] It is mainly used in national defense construction engineering, transportation construction, energy industry construction and production, raw material industry construction and production of mines, agricultural and water conservancy construction, industrial and civil building, urban construction, environmental protection and other fields.
[0004] In the world, the denomination of this industry is basically the same, among which the United States and the United Kingdom call it construction machinery and equipment, Germany calls it construction machinery and device, Russia calls it construction and road building machinery, and Japan calls it construction machinery. In China, some products are also called construction machinery, while in the mechanical system according to the State Council, the industry is called engineering machinery, which has been continued. The product range of the industry in each country is basically the same, and China's engineering machinery and other countries also adds railway line engineering machinery, forklifts and industrial handling vehicles, decoration machinery, elevators, pneumatic tools and other industries.
