Construction machinery is widely utilized in fields such as national defense construction, transportation infrastructure, energy industry construction and production, raw material industries (including mining), agriculture, forestry, and water conservancy, industrial and civil architecture, urban development, and environmental protection.
Construction machinery constitutes a vital component of the equipment manufacturing industry. Broadly speaking, any mechanical equipment essential for comprehensive mechanized construction operations-including earthworks and stonework, pavement construction and maintenance, mobile hoisting and handling tasks, and various general building projects-is classified as construction machinery.
Its primary applications lie in national defense projects, transportation infrastructure development, energy industry construction and production, raw material sectors (such as mining), agriculture, forestry, and water conservancy projects, industrial and civil architecture, urban development, and environmental protection initiatives.
Across the globe, the terminology used to designate this industry is largely consistent: the United States and the United Kingdom refer to it as "construction machinery and equipment"; Germany calls it "construction machinery and apparatus"; Russia uses the term "construction and road-building machinery"; and Japan refers to it as "construction machinery." In China, while certain products are occasionally referred to as "construction machinery," the sector as a whole has been officially designated as "engineering machinery" within the mechanical industry system-a classification established by the State Council's approval document for the industry's formation-and this terminology has remained in use ever since. Although the scope of products encompassed by this industry is broadly similar across different nations, China's classification of "engineering machinery" is notably more comprehensive than that of other countries, incorporating additional categories such as railway track machinery, forklifts and industrial handling vehicles, interior finishing machinery, elevators, and pneumatic tools.
