China is known for its gigantic-scale mind-set, there’s nothing we can do about it and it is always there ready to surprise us. To prove my point, just look at this:
This monster, known as the SLJ900/32, made by the Beijing Wowjoint Machinery Company, is a 580 ton, 300 foot long and 24 foot wide mega machine that looks more like a train than a crane and acts a lot like a Stretch Armstrong action figure. Instead of using a stationary or crawler crane to lift the girder of a bridge from the ground and drop it into its place, the SLJ900/32 drives the girder onto the previously placed girder, slowly extends its arms to the next support platform, pushes the girder towards the front of the machine and then lowers it into place.
