Construction machinery refers to the mechanism used in the project construction. It is widely used in construction, water conservancy, electric power, roads, mines, ports and national defense sectors etc.

Generally speaking, all earthwork construction projects, road construction and maintenance, mobile crane loading and unloading operations and a variety of construction required for the comprehensive mechanization of the construction works, known as construction machinery. It is mainly used for national defense construction, transportation construction, energy and industrial construction and production, mining and other raw materials, industrial construction and production, agriculture, forestry, water conservancy construction, industrial and civil construction, urban construction, environmental protection and other fields.

Construction machinery can be divided as follows according to the main application:

Excavating machinery
For example: Single-bucket excavator (can be divided into crawler excavator and tire excavators), multi-bucket excavator (can be divided into wheel bucket excavator and chain bucket excavators), multi-bucket trencher ( Also can be divided into wheel bucket trenching machine and chain bucket trencher machine), rolling excavators, milling excavators, tunnel boring machine etc..

Shovel soil transport machinery
Such as bulldozers (can be divided into tire-type bulldozer and crawler-type bulldozers), scraper (can be divided into tracked self-propelled scraper, tire self-propelled scraper and towed scrapers), Loaders (can also be divided into tire loaders and crawler loaders, motor graders (can be divided into self-propelled grader and towed grader), vehicles (vehicles can be divided into uniaxial and biaxial traction vehicles), flatbed and the dump truck and so on.

Crane
Such as tower cranes, self-propelled crane, derrick cranes, grab cranes, etc.

Compaction machinery
Such as tire roller, smooth wheel roller, single-foot roller, vibratory rollers, compaction machine, tamping machine.

Piling Machinery
Such as drilling machines, diesel hammers, vibration pile driver, pile driver.

Reinforced concrete machinery
Such as concrete mixers, concrete mixing plant, concrete pump, concrete mixing truck, concrete jet, concrete vibrators, steel processing machinery.

Road construction machinery
Such as the flat machine, ballast cleaning machine, etc.

Charge
Such as the trolley drill, pneumatic rock drilling machines, electric drilling machines, internal combustion rock drill, and hole drilling machines, etc.

Other construction machinery
Such as bridge building equipment, pneumatic tools (pneumatic tools), etc.
