The history of tower cranes

 Tower crane, short for "tower crane", also known as "tower crane", is a kind of lifting equipment in construction. The tower crane originated in Europe. The first original tower crane appeared in 1912-1914. In 1923, the prototype of the first modern tower crane was made. In 1930, Germany began mass production of tower cranes and used them for construction.

  China produced its own tower cranes in the 1950s. In 1954, my country's first TQ2-6 tower crane was trial-produced by the then Fushun Heavy Machinery Factory, which was subsequently produced in Shanghai Construction Machinery Factory and Harbin Construction Machinery Factory. In 1984, the Machinery Bureau of the Ministry of Construction introduced four types of tower crane data and technical training, including Potain GTMR360B, TOPKITFO/23B, FO/23B, H3/36B, at a price of 3.5 million yuan. Sichuan Jianji Factory is responsible for production. Due to the reasonable introduction of objects and adequate preparations, the production of tower cranes has been rapidly launched in China, which has made important contributions to national construction. The introduction of tower crane technology in 1984 will surely leave an important chapter in the development history of China's tower crane industry.

  At the beginning of the 21st century, China's economy has ushered in a new round of rapid growth, and the real estate and construction industries have become new engines for economic development. Driven by these two industries, China's tower crane industry has presented a rare opportunity for development. A number of enterprises have risen rapidly under the impetus of demand, not only winning the domestic market, but also establishing a brand overseas. The flat-top tower crane of Yongmao Construction Machinery enjoys a high reputation at home and abroad; the tower crane of Sichuan Construction Machinery marked by "SCM" is praised as "the first tower in China" by users; the tower crane of Zoomlion D5200-240 tower crane project The signing of the contract will not only rewrite the history of "the world's largest tower crane", but will also become a milestone in the development of global tower crane technology.

  It is undeniable that with the rapid rise in housing prices, the development of China's real estate industry has attracted widespread attention from all parties. Since the beginning of 2010, the real estate industry has experienced a series of strict regulation, the whole market has become cautious, and the wait-and-see sentiment has been rising. People in the industry should still clearly remember that in the fourth quarter of 2008, with the onset of the financial crisis, the real estate industry underwent a round of rapid adjustments that lasted for half a year. Many construction projects were temporarily stagnant. Small tower crane companies and lessors were hit hard.
