SANY Group began in 1989 as a small welding material factory. Its founders are Liang Wengen, Tang Xiuguo, Mao Zhongwu and Yuan Jinhua. Each year, SANY Group re-invests 5-7% of its sales revenue into the R&D, making it possible to expand its product lines to concrete, road, port, hoisting, pile driving, excavating machineries and wind energy products. Now as one of the most successful enterprises in China, SANY becomes one of the global top construction manufacturers. In 2007 and 2009, SANY Heavy Industry's self-developed 66m and 72m concrete pump trucks created Guinness World Records twice as the concrete pump with the longest boom. It demonstrated to the world that China became a leader in concrete pumping technology. On Sep 19th, 2011, SANY Heavy Industry's 86m concrete pump truck, which owns the longest boom in the world, successfully rolled off the production line. Once again, SANY has shown that there is no limit for SANY in concrete pumping technology.
