Large scale has become an important development trend of construction machinery in the future
DateTime:[2016-1-11]    Browse the number: 1957

Taken together, the Chinese engineering machinery is developing in the direction of energy saving, intelligent, large-scale, the former two don't have to say more, almost for all of the engineering machinery enterprises, both must follow the law of development. But the last one is different, it is not the goal of every engineering machinery enterprises, of course, also is not anyone can "chosen" bigness, in a sense, the large often means more powerful strength, means that the improvement of technology and adapt to the conditions of ascension.

Throughout engineering machinery more than hundred years development course, more than 50 years ago, its size and small agricultural machinery, slowly to the size and the small and medium-sized automobile fitting for development, then there are greater than that of general auto equipment, then a crawler crane this several storeys high.


In recent years, with increasing worldwide, the large and super large engineering, such as nuclear power plants, DAMS and other large infrastructure construction, and mining, large construction projects, engineering machinery, such as common in order to ensure the construction convenient and quick, needs to promote the further large-scale equipment, large-scale construction machinery has thus become an important development trend.


Large scale, it is important to note that the product is not a simple sense of the geometric series expansion, such as multiplication in tonnage or other computing unit, the requirement for technology is becoming more and more high. And can develop a reliable and durable large-scale equipment also became a measure of engineering machinery enterprises is an important indicator of overall strength.
