The world's largest 4,000-ton crawler crane was successfully hoisted in Shandong
Our reporter Liu Jin reported: The world’s largest 4000-ton crawler crane SCC40000A, developed and manufactured by Sany Heavy Industry Co., Ltd., has successfully completed the lifting of No. 4 1500-ton propylene tower at the site of the Luqing Petrochemical Project in Shouguang, Shandong. "It has truly realized the replacement of a full range of imported crawler crane products.
SCC40000A is a large-tonnage crawler crane independently developed by Sany Heavy Industry in accordance with construction needs. It is also the largest tonnage crawler crane in service in the world. Its maximum lifting moment is 90,000 tons, the maximum lifting weight is 4000 tons, and it has more than 20 invention patents, 2 of which are international invention patents.
According to Zhang Yang, the project manager of the large-tonnage product institute of Sany Equipment Research Institute, the main engine of this product adopts the configuration of "four crawlers and eight drives", and the herringbone double boom is 120 meters long, plus the overlifting mast, counterweight, hook, etc. With an area of nearly 3,000 square meters, 150 trucks with a load of 30 tons are required to transport all of them.
Industry experts told reporters that super-mass crawler cranes are the most technically complex products with the highest manufacturing precision in the machinery and equipment industry, and they are also an intuitive manifestation of the development strength of host manufacturers. For a long time, my country's large-tonnage crawler lifting equipment has been monopolized by foreign brands, and the level of R&D and manufacturing of domestic related products has lagged far behind market demand.
"Strengthening core technology research is a warning from history, and it is an inevitable choice for China to accelerate its development as a manufacturing power. Starting from scratch to the frontier of the world's'intelligent manufacturing', Chinese equipment is no longer what it used to be." The expert said.
