If you ask me in a few words to explain what the SLJ900 / 32 is, I answer you like this: it is a robot on wheels that weighs 580 tons, is 92 meters long and 7 and a half meters wide.
If the size itself is not enough to dislocate your jaw with amazement, I will continue to tell you that in China this mega-machine produced in Beijing is used to build bridges. Instead of using construction sites and means of transport, everything is concentrated in a single huge device that fixes the parts of a bridge in position, reducing the construction time in a crazy way.
Here is a live video and an animation that better illustrates how this 'robot' works.
