A Zoomlion 3200-ton crawler crane lowers the dome of a nuclear reactor in China

A Zoomlion 3200-ton crawler crane lowered down a 340-ton dome on top of the 45 meter high reactor in China.  Over 100 sensors are embedded in the crane and can detect tiny details like pressure, load and speed, etc. Then operation parameters can be automatically adjusted to ensure lifting accuracy of less than 2mm, making the operators job much easier.
