The world's largest crawler crane, the Sany SCC86000TM (3,600T), successfully rolled off the assembly line on May 18, 2011.Sany Heavy Industry formed the world's largest Sino-US R&D team composed of nearly 500 people and built the most advanced crawler crane production line of the world. To develop SCC86000TM crawler crane, Sany Heavy Industry invested more than RMB 100 million to set up the first supercomputing centre in the industry, independently developed lifting simulation software, and imported the world's most advanced processing equipment and testing devices. During the development stage, Sany Heavy Industry widely sought suggestions from foreign and domestic industrial experts and passed technological review by industrial experts.Development of the product also won support and guidance from authoritative organisations like State Nuclear Power Technology Corporation and China Nuclear Engineering Group.
To mark the occasion of introducing the world's largest crawler crane, Sany held a press conference in China with the participation of government officials from Jiangsu provincial government, leaders of trade associations, industrial experts and major media. All the participants applauded roll-off of SCC86000TM (3600T) from the assembly line, which fills the absence of super-large crawler crane in China and signals that China has mastered the manufacturing competence and technology to independently produce the world's top crawler crane, and that China's crawler crane industry has reached the world's summit.According to the company, Sany SCC86000TM crawler crane's maximum lifting torque is more than 86,000 tonne metre, with lifting capacity of 3,600 tonne at maximum, higher than the maximum torque and capacity of any 3,200T crawler crane of the world. Its development adopted the most sophisticated design methods such as limit state design, digital prototyping and top-down design, overcoming the design challenges of non-linear structures and large deformation. This crawler crane pioneered in using the GB3811-2008 high-risk coefficient recommended for lifting machines used for nuclear industry and achieved a substantial break-through in structural design and control system. As of now, the product has applied for 30 patents, and some technologies have also applied for patents in countries like Germany and the US. Industrial experts remarked, "So far, this is the crawler crane equipped with the biggest lifting torque and most advanced technology in the world." Participants say that SCC86000TM is another historic contribution made by Sany to the Chinese crawler crane industry, and that its successful launch signals end of monopoly of foreign brands in the big-capacity crawler crane field and shows China's world-class R&D and manufacturing competence. Advent of SCC86000TM will definitely make more contribution to upgrade of Chinese crawler cranes. Sany's strong R&D and manufacturing competence allowed the company to create records one after another in the domestic crawler crane industry since 2006. When Sany rolled off China's first 400T crawler crane, it was recognised as the No. 1 crawler crane of China then and participated in Chilean mining accident in 2010. In June 2006, Sany SCC6500 was produced. In 2008, Asia's first 1,000T crawler crane rolled off the production line and was honoured as the No. 1 crawler crane of Asia. In 2010, the SCC16000 1600T crawler crane was launched and applied in the nuclear power generation industry. On May 27 this year, the Sany 1000T crawler crane successfully completed dome installation for Taishan Nuclear Power Plant. As the first Chinese crawler crane used for lifting key parts of nuclear power generation and islands, Sany SCC10000 and SCC16000, two models with capacity of over one thousand tonne, have been used in dome installation for nuclear power plants eight times, ending the monopoly of foreign brands in lifting key parts of nuclear power generation and islands. SCC86000TM will be mainly applied in nuclear engineering sector. Sany is expected to write a new chapter of Chinese crawler crane in the history of nuclear engineering in the near future.
