Concrete pump from the beginning of the merits of the wind also look at the present
After PM and CIFA have been China acquisitions, Xugong successful acquisition of Shi Weiying, which marks the world's top concrete giant were Chinese enterprises into her arms, Chinese have become the world leader in concrete pump. And behind this, go in for nearly a century in the concrete pump and Time passes very quickly., through which the development of innovation? Today, let us follow the history, repeat the development of this century, commemorate and look back, take you into a concrete pump hundred years of development history.
Concrete pump, also known as concrete pump, is composed of pump body and conveying pipe. It is a kind of machine which can transport concrete along pipeline continuously by using pressure. It is mainly used in building, bridge and tunnel construction. At present, mainly divided into gate valve concrete pump and S valve concrete pump, another kind is the pump body installed in the automobile chassis, and then equipped with retractable or bent cloth rod, and composed of pump truck.
A hundred years from the beginning
The development of concrete pump has nearly a hundred years of history, after two baptism of war, and finally embarked on the road of construction machinery.
As early as 1907, France began to study the concrete pump, someone was granted the patent right.
After several decades of development, in 1957, the world's first hydraulic double cylinder concrete pump developed by Shi Weiying, Germany, to promote the global concrete power system climbing the peak.
In 1958, the first Deda (Shi Shi Wei yingzi company) mixing the official line, not only shows the application of Deda strong R & D strength, but also indicates that the mankind to a new journey in the field of concrete transport vehicle.
Stride in China
In China, imported concrete pump was introduced from abroad in 50s, for example, the Soviet Union's 252 type concrete pump was used in the construction of Wuhan, Yangtze River bridge. Because of the insufficient conditions, the continuous failure occurred, and did not cause the attention of construction units.
In 1988, Xuzhou heavy machinery factory introduced Putzmeister's technology, the production of M32-4 type concrete pump car arm height 31.6m, weight 90m3/h, concrete conveying pump concrete pressure 7MPa, the S valve, the product quickly into the market.
In September 28, 1992, the predecessor of ZOOMLION - Changsha hi tech Development Zone Zhonglian Construction Machinery Industry Co., Ltd. was formally established; in November 22, 1994, 31 heavy industry group Co., Ltd. was established, many enterprises have joined the concrete mixer industry.
Romantic look at today
In recent years, concrete machinery as one of the most important plate of construction machinery, the rapid development momentum, truly realized the world advanced level, which laid the foundation for the long-term development of China's concrete machinery. On this basis, in 2013, the concrete machinery enterprises in the international market expansion in full swing, China's concrete machinery products also towards lightweight, large-scale, high-end, integrated direction of continuous development. Through the continuous extension of the industrial chain, the current industry has formed a business mix, dry mixed mortar, machine-made sand and gravel, wet spray and other four sets of products, its function covers production, transportation, recycling, reuse and other aspects.
In the future, the biggest opportunity for the development of the concrete machinery industry is still from the new urbanization dividend, "going out" overseas route is still the firm route of the major manufacturers. But it is undeniable that the gathering of the world's top energy China concrete machinery enterprises, has launched a new chapter in the international arena where the.
