निर्माण मशीनरी क्या है?

Construction machinery‌ refers to the sum of mechanical equipment used in civil engineering, construction engineering, water conservancy, mining, ports, national defense and other basic construction projects to replace or assist people in operations. These mechanical equipment are mainly used in comprehensive mechanized construction projects such as earthwork construction projects, road construction and maintenance, and mobile lifting and loading and unloading operations.

‌Pile machinery‌: such as pile drivers, drilling machines, etc.

‌Rock drilling machinery‌: such as rock drilling trolleys, pneumatic drills, etc.

Application fields

Construction machinery is widely used in infrastructure construction, real estate, mining and other fields. Specific applications include:

Infrastructure construction: such as road construction, bridge construction, etc.

Real estate: such as the construction of residential areas and commercial buildings.

Mining: such as mining, ore transportation, etc.

Development history and technological progress

The development of construction machinery can be traced back to the first industrial revolution in the 18th century, when steam-driven excavators and rollers appeared. In the early 19th century, construction machinery in Europe was initially formed, and with the invention of internal combustion engines and motors, construction machinery has developed rapidly. Since the 1940s and 1950s, breakthroughs in material technology and network technology have greatly improved the production efficiency of construction machinery. In recent years, the global construction machinery market has shown a fluctuating upward trend, especially since 2018, the global sales of construction machinery equipment have exceeded 1 million units. As the world's largest construction machinery production base, China accounts for about 46% of the market share. In 2024, China's total output value of construction machinery is expected to reach 1.6 trillion yuan, an increase of 8.6% year-on-year.

To sum up, construction machinery plays an important role in modern engineering construction, and its development history and technological progress continue to promote the progress and innovation of the industry.
