construction machinery

The floorboard of construction machinery used in engineering construction. Widely used in construction, water conservancy, electric power, roads, mines, ports and national defense and other engineering fields, a wide variety.

brief history

It has been a long history for human beings to replace manual labor with lifting tools. History shows that oranges and windmills were used in China around 1600 BC. The former is a heavy lever, and the latter is the prototype of a manual winch. In ancient Egypt and Rome, lifting tools were also widely used. The development of modern construction machinery began after the invention of the steam engine. /kloc-At the beginning of the 9th century, excavators, rollers and cranes driven by steam engines appeared in Europe. Since then, construction machinery has developed rapidly due to the invention of internal combustion engine and electric motor. After the Second World War, it developed more rapidly. Its variety, quantity and quality directly affect the development of a country's production and construction, so all countries attach great importance to it.

① Excavating machinery. Such as single bucket excavators (which can be divided into crawler excavators and tire excavators), multi-bucket excavators (which can also be divided into wheel bucket excavators and chain bucket excavators), multi-bucket trenchers (which can also be divided into wheel bucket trenchers and chain bucket trenchers), roller excavators, milling excavators, tunnel boring machines (including shield trenchers) and so on.

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

Crawler crane ③ Lifting machinery. Such as tower crane, self-propelled crane, mast crane, grab crane, etc.

Liugong roller ④ Compaction machinery. Such as tire roller, smooth roller, one-legged roller, vibratory roller, tamping machine, tamping machine, etc.

⑤ Piling machinery. Such as drilling rig, diesel pile driver, vibration pile driver and pile driver.

⑥ Reinforced concrete machinery. Such as concrete mixer, concrete mixing station, concrete mixing building, concrete delivery pump, concrete mixer truck, concrete jet machine, concrete vibrator, steel processing machinery, etc.

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

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

Pet-name ruby other construction machinery. Such as bridge erecting machines and pneumatic tools (pneumatic tools).
