Definition and classification of construction machinery
Construction machinery is an important part of my country’s equipment industry. In summary, the mechanical equipment necessary for earthwork construction projects, road construction and maintenance, mobile lifting and loading and unloading operations, and comprehensive mechanized construction projects required for 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.
At present, my country’s construction machinery is divided into the following 14 types:
(1) Excavation machinery. Including single bucket excavators, multi-purpose excavators, backhoe loaders, tunnel boring machines, etc.
(2) Hoisting machinery. Including towers, cars, tires, crawlers, masts, cables, grabs, pipeline cranes, winches and construction hoists.
(3) Shovel transportation machinery. Includes dozers, scrapers, loaders, graders, haulers, flatbeds and dump trucks.
(4) Compaction machinery. Including static rollers, vibratory rollers, tire rollers and compactors.
(5) Piling machinery. Including diesel piling hammer, diesel pile driving frame, vibrating pile hammer, vibrating pile frame, pile driver and drilling machine.
(6) Steel bars and prestressed machinery. Including steel reinforcement, processing, welding machinery, prestressed processing machinery and equipment, etc.
(7) Concrete machinery. Including concrete mixers, mixing buildings, mixing stations, mixing trucks, transfer pumps, jets, pouring machines and vibrators.
(8) Road machinery. It is a machine for highway pavement construction and maintenance. It includes asphalt sprayers, asphalt concrete pavers, concrete pavers, concrete vibrators, road plowing machines, soil mixers, stone pavers, stone chip spreaders, etc.
(9) Decoration machinery. It is construction and decoration machinery, including mortar preparation and spraying machinery, ground finishing machinery, decoration lifting platforms and hanging baskets, handheld machines, etc.
(10) Rock drilling machinery and pneumatic tools. Including various rock drills, rock drilling rigs, pneumatic tools, etc.
(11) Forklift. Including various forklifts and loading and unloading machinery.
(12) Railway line machinery. It is a special machine for railway line construction and maintenance. Including tamping machines, track lifting machines, cleaning machines, comprehensive line maintenance trains and other line maintenance machinery.
(13) Military engineering machinery.
(14) Other special construction machinery.
What are the construction machinery?
① Excavating machinery such as single bucket excavator (can also be divided into crawler type Excavators and tire-type excavators), multi-bucket excavators (can also be divided into wheel bucket excavators and chain bucket excavators), multi-bucket trenchers (can also be divided into wheel bucket trenchers and chain bucket excavators) trenching machines), rolling excavators, milling excavators, tunnel boring machines (including shield machines), etc.
② Shovel transportation machinery such as bulldozers (can also be divided into tire bulldozers and crawler bulldozers), scrapers (can also be divided into crawler self-propelled scrapers, tire self-propelled scrapers and Trailed scrapers), loaders (which can be 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 transporters and double-axle traction transporters), 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, compactors, tamping machines, etc.
⑤ Piling machinery such as drilling machines, diesel piling machines machine, vibration pile driver, breaker, etc.
⑥ Reinforced concrete machinery such as concrete mixer, concrete mixing station, concrete mixing building, concrete pump, concrete mixing truck, concrete spray machine, concrete vibrator, Rebar processing machinery, etc.
⑦Road machinery such as graders, ballast cleaning machines, 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 engineering machinery such as bridge erecting machines, pneumatic tools (pneumatic tools), etc.
