Construction machinery is an important part of the equipment industry. In a nutshell, the mechanical equipment necessary for comprehensive mechanized construction projects required for earth and stone construction projects, road construction and maintenance, mobile crane loading and unloading operations, and various construction projects are called engineering machinery.
It is mainly used in national defense construction projects, transportation construction, energy industry construction and production, mining and other raw material industrial 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 title of this industry is basically the same. 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.
Construction machinery classification
The product range of China’s construction machinery industry is mainly divided into the major categories of general equipment manufacturing and special equipment manufacturing.
These 18 categories of products include excavating machinery, earth shoveling and transporting machinery, construction hoisting machinery, industrial vehicles, compaction machinery, piling machinery, concrete machinery, steel and prestressing machinery, decoration machinery, rock drilling machinery, pneumatic tools, railways Route machinery, military construction machinery, elevators and escalators, special parts for construction machinery, etc.
Ordinary heavy industry construction machinery
Such as single bucket excavators (which can be divided into crawler excavators and wheeled excavators), multi-bucket excavators (also can be divided into bucket wheel excavators and chain bucket excavators), multi-bucket trenching excavators Machine (also can be divided into bucket wheel trencher and bucket chain trencher), rolling excavator, milling excavator, tunnel boring machine (including shield machinery), etc.
②Shovel transportation machinery
Such as bulldozers (which can be further divided into tire bulldozers and crawler bulldozers), scrapers (which can be further divided into crawler self-propelled scrapers, tire self-propelled scrapers, and drag scrapers), Loaders (also can be divided into tire loaders and crawler loaders, graders (also can be divided into self-propelled graders and drag graders), transport vehicles (also can be divided into single-axle transport vehicles and double-axle traction Transport vehicles), flatbed trucks and dump trucks.
③ Lifting machinery
Such as tower cranes, self-propelled cranes, mast cranes, grab cranes, etc.
④ Compaction machinery
