Construction machinery is an important part of equipment industry. Generally speaking, the mechanical equipment necessary for earth and rock construction projects, road construction and maintenance, mobile lifting handling operations and comprehensive mechanized construction projects required by various construction projects are called construction machinery.

It is mainly used in national defense construction projects, transportation construction, energy industry construction and production, mining and other raw material industry construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, environmental protection and other fields.

In countries around the world, the name of this industry is basically the same, of which the United States and the United Kingdom are called construction machinery and equipment, Germany is called construction machinery and equipment, Russia is called construction and road construction machinery, and Japan is called construction machinery. In China, some products are also called construction machinery, and in the mechanical system, they are collectively referred to as construction machinery when The State Council formed the industry approval document, which has continued to the present. Countries delimit the product range of the industry is roughly the same, and China's construction machinery compared with other countries has also increased railway line construction machinery, forklifts and industrial handling vehicles, decoration machinery, elevators, pneumatic tools and other industries.

The product range of China's construction machinery industry is mainly separated from the general equipment manufacturing professional and special equipment manufacturing categories. In 1979, the State Planning Commission and the first Ministry of machinery industry prepared the "Seventh Five-Year Plan" development plan for the development of China's construction machinery industry, the product range covers 18 categories of products in the construction machinery industry, and the national machinery industry planning after the "Seventh Five-Year Plan" development plan has confirmed the 18 categories of construction machinery products, and its product range has continued to this day.

These 18 categories of products, including excavation machinery, shovel transport machinery, engineering lifting machinery, industrial vehicles, compaction machinery, piling machinery, concrete machinery, reinforcement and prestressed machinery, decoration machinery, rock drilling machinery, pneumatic tools, railway route machinery, military construction machinery, elevators and escalators, special parts of construction machinery, etc.
