China has become the world's largest producer and exporter of construction machinery, and construction machinery made in China is going all over the world. How do Chinese cranes step by step become bigger and stronger? Let’s learn more about the development history of cranes and hoists in China.
Global crane output distribution: China accounted for more than half
The China’s electric hoist was designed and produced by imitated from the 1950s, In 1949 July, Shanghai General Machinery Factory first trial imitated about Germany DEMAG K-type 1.5t and 3t wire rope electric hoist successfully, and put into small scale production, but the Shanghai General Machinery Factory were turned conversion turbine in 1954 . But in 1953 ,Tianjin Crane Equipment Factory (former Tianjin Seventh Machinery Factory) had Imitated the Soviet Union in the 40's TB-type hoist trial of 1t and 2t wire rope electric hoist, It was stereotyped as TV electric hoist.
In 1963, Tianjin crane machine factory had design and production of explosion-proof electric hoist, and then electric single girder explosion-proof crane and suspension crane products came out one after another. In 1964, it was began to design and production the type of CD and MD hoist from Tianjin Lifting Equipment Factory, Shanghai Lifting Equipment Factory, Chongqing Crane Factory, Dingxi Crane Factory, Xi'an Crane Factory, Shenyang Crane Factory and Beijing lifting equipment and Transporting Machinery Institute Series gourd. The type of CD and MD hoist are the second generation of China's hoist development, it is the current mainstream products.
The type of A571 electric single girder cranes and ΠK electric single girder suspension cranes are match with the type of CD and MD hoist , but because the reason of structural and performance , there are many problems. In 1974, Tianjin lifting equipment factory had updated the type of A571 electric single-girder crane and the ΠK electric single-girder suspension crane, and designed and production by themselves in DL type electric single-girder crane and DX electric single girder suspension crane match with CD and MD type hoist. On the basis of DL type and DX type production in 1976, It was designed and production by joint venture of Tianjin Crane Equipment Factory, Kaiyuan Crane Factory, Chongqing Crane Factory, Changsha Crane Factory, Luoyang Crane Factory and Beijing lifting equipment and Transporting Machinery Institute. For the LD-electric single-girder cranes and LX electric single-girder suspension cranes, becoming China's second-generation electric single-girder cranes and suspension cranes products, has been produced so far is still the leading domestic product. The 70s of last century, China has also came out the LB explosion-proof electric single-girder crane, LXB-type explosion-proof electric single girder suspension cranes and LH electric hoist double beam cranes and other products.
Hoist as the lifting mechanism of electric single-girder suspension crane, the Shanghai crane factory is still the earliest imitation of the former Soviet Union in the 40's ΠK truss-type single-beam cranes, and carried out a series of production for China's first generation of electric single Beam suspension crane, but also has been produced until 1987 was discontinued (no reproduction since January 1987).
From the late 1970s to the early 1980s, hoist cranes have entered a new step of the introduction and development. Tianjin Lifting Equipment Factory had imported the German STAHL company's AS-type full range of wire rope hoist technology; There are three company jointy by Nanjing Crane Machinery factory, Beijing Lifting Equipment Factory and Shanhaiguan Lifting Equipment Factory had imported the German DEMAG's chain hoist technology; In the mid-1980s, It designed and production mainly by Nanjing Lifting Machinery about the H-type wire rope electric hoist, It designed and production mainly by Chongqing Crane Factory about the joint development gourd gantry crane products. The import of AS type hoist technology with the world advanced 80's level, it is the representatives of the China's third-generation hoist.
The type of LH electric hoist double beam crane is in the 70's Wuhan crane factory as the representative, it developed by themselves, the type of HC electric hoist as the lifting mechanism of China's first generation of electric hoist double-beam cranes.
After learning the history of cranes about China, Dongqi Crane know that we should try our best to develop crane technology to make it more advanced. Now Dongqi Group can provide you types of cranes and hoists, if you need, please contact us freely.
