Sany Heavy Industry was founded in 1994 and listed on the A-share market in 2003. In 2011, with a market value of 21.584 billion US dollars, it was ranked among the top 500 global market capitalization of the Financial Times, and was the only Chinese machinery company on the list so far. In 2012, it acquired Putzmeister, Germany, the "world's first concrete brand", and has now developed into one of the largest construction machinery manufacturers in China and the largest concrete machinery manufacturer in the world. Sany Heavy Industry's performance in concrete machinery and equipment is more eye-catching, and its performance on excavators is inferior: it sacrifices high-power engines, so its performance is average, the digging force is small, and the fuel consumption is low, which is only suitable for earthmoving vehicles. And the accessories are also expensive, and the ease of maintenance is not outstanding.
