The Production Of Tower Cranes
2024-02-01
According to records, the first patent for tower cranes for construction was issued in 1900. A crane with a jib with a fixed tower appeared in 1905, a prototype of a modern tower crane was made in 1923, and the first relatively complete modern tower crane appeared in the same year. In 1930, Germany had begun mass production of tower cranes and used them in construction. In 1941, the German Industrial Standard DIN 8770 for tower cranes was published. The standard stipulates that the product (tm) of the lifting load (t) and the amplitude (m) is used together to express the lifting capacity of the tower crane in terms of the moment of gravity.
My country's tower crane industry started in the 1950s. Compared with the recession of the tower crane industry caused by the weak construction industry in Central and Western European countries, my country's tower crane industry is in a period of rapid development.
However, due to the promotion of a series of favorable policies such as my country's urbanization strategy, the tower crane market has been guaranteed to a certain extent, and the overall development of the industry is approaching developed countries such as Europe and the United States. However, as tower crane technology is becoming more and more intelligent and green, and tower crane enterprise management tends to be internationalized, the development of small and medium-sized tower crane enterprises in China is not optimistic.
Large companies such as XCMG, Zoomlion and Sany have gone abroad to open up foreign markets. In particular, Zoomlion has become the world's largest tower crane company. Without exception, these giant companies have a very complete R&D, quality assurance system and operation management mechanism, and can participate in the competition for international market share. But for small and medium-sized enterprises, there is no such opportunity. Due to their own technology and capital constraints, coupled with the intensification of industry price wars and serious payment defaults, the situation facing the entire industry is not clear.
