The 1950s was the beginning and imitation period of Chinese gourd cranes. Before the establishment of Xinjin Country, the gourd crane was a blank field in China, with nothing to say. In the early 1950s, it started by copying and imitating similar products from the Soviet Union.In July 1949, the original Shanghai General Machinery Factory, China Crane * *, produced a K-shaped steel wire rope electric hoist, a third-generation product modeled after German DEMAG company. This was China's own manufactured steel wire rope electric hoist. The factory also produced a small batch of 1.5t and 3t general-purpose steel wire rope electric hoists for lifting purposes. However, the factory switched to producing steam turbines instead of electric hoists in 1954.In 1953, Tianjin Crane Equipment Factory (renamed Tianjin Seventh Machinery Factory, which was formed by several small factories in Tianjin Santiaoshi) began to imitate the TB type steel wire rope electric hoist produced by the Soviet Union in the 1940s. At that time, 1T and 2T products had already been trial produced, and in 1954, 3T and St products had also been trial produced. In the early 1950s, the code of tuberculosis in China was TB. At that time, tuberculosis was an incurable disease. The letter B of the Soviet TB type gourd, the Russian pronunciation of which was the same as the letter V of the Chinese phonetic alphabet, changed the TB type to the TV type wire rope electric hoist. In 1957, the Tianjin factory completed the trial production and production of the full series of TV type 0.25-5t and SIN type 10t (double drum two 5t TV type hoist combination type) products. From then on, Yaojin Crane Equipment Factory became the manufacturer of * * Daili Wire Rope Electric Hoists in China.In 1954, Tianjin Crane Equipment Factory successively imitated the Soviet Union's HK type electric single beam crane and IIK type electric single beam suspension crane. By 1956, they were able to produce and supply in batches. In 1957, Tianjin Crane Equipment Factory and Beijing Crane Machinery Factory, which was also producing electric single beam cranes at the time (later transitioning to automobile cranes), jointly revised and reorganized the drawings. The Soviet Union's HK type electric single beam crane was redesigned and finalized as the A571 type electric single beam crane (A represents bridge type at that time, 571 represents the 1957 * * rectification). The Soviet Union's LK type electric single beam suspension crane model 11K has not been changed. Later, Tianjin Qigong Equipment Factory successively imitated Soviet technology to produce DZ monorail grab lifting equipment with TV type hoists of 0.5 to 1.5m in length. From then on, Tianjin Crane Equipment Factory became a Chinese manufacturer of * * generation hoist type cranes. In 1987, the Heavy Mining Bureau of the former Ministry of Machinery issued an order to phase out the TV type electric hoist, A571 type electric single beam crane, and LK type electric single beam suspension crane. From then on, the Chinese * * generation hoist type crane completed its mission.The 1950s was the beginning and imitation period of Chinese gourd cranes.

With the development of China's economy, port cranes, dock cranes and other lifting machinery have also made significant progress in various aspects, as can be seen from the growth of sales and profits of related enterprises. However, it should also be noted that the difficulties encountered by lifting machinery in export, such as technological barriers and sales restrictions in developed countries, have become obstacles for export enterprises to form their own advantages and overcome national characteristics for a long time. This deserves the joint attention of the government and enterprises.
