Concept And Classification Of Construction Machinery

Engineering machinery is a general term for construction machinery used in engineering construction. It is widely used in engineering fields such as construction, water conservancy, electric power, roads, mines, ports and national defense.

There are many types, which are mainly divided into:

① Excavation machinery. Such as single bucket excavators (also divided into crawler excavators and tire excavators), multi-bucket excavators (also divided into wheel bucket excavators and chain bucket excavators), multi-bucket trenching machines (also divided into It can be divided into wheel bucket trenching machine and chain bucket trenching machine), rolling excavator, milling excavator, tunnel boring machine (including shield trench machinery), etc.

②Shovel transport machinery. Such as bulldozers (which can also be divided into tire bulldozers and crawler bulldozers), scrapers (which can also be divided into crawler self-propelled scrapers, tire self-propelled scrapers and towed scrapers), loaders (which can also be divided into Divided into tire loaders and crawler loaders, graders (which can also be divided into self-propelled graders and towed graders), transport vehicles (which can also be divided into single-axle transport vehicles and dual-axle traction transport vehicles), flatbed trucks and dump trucks, etc.

③ Hoisting machinery. Such as tower cranes, self-propelled cranes, mast cranes, grab cranes, etc.

④ Compaction machinery. Such as tire rollers, smooth wheel rollers, single-legged rollers, vibratory rollers, tamping machines, tamping machines, etc.

⑤ Piling machinery. Such as drilling machines, diesel pile drivers, vibration pile drivers, pile drivers, etc.

⑥Reinforced concrete machinery. Such as concrete mixers, concrete mixing stations, concrete mixing buildings, concrete pumps, concrete mixing trucks, concrete sprayers, concrete vibrators, steel processing machinery, etc.

⑦Road machinery. Such as leveling machine, ballast cleaning machine, etc.

⑧Rock drilling machinery. Such as rock drilling rigs, pneumatic rock drills, electric rock drills, internal combustion rock drills and down-the-hole rock drills, etc.

⑨Other construction machinery. Such as bridge erecting machines, pneumatic tools (pneumatic tools), etc.
