This is the SLJ900/32 Bridge Girder Erection Mega Machine. Created by the Beijing Wowjoint Machinery Company, it is 91.8 meters long and weighs in at a whopping 580 tons.
This impressive piece of engineering takes the place of giant, immobile cranes, which take up massive amounts of space in construction sites and require much more difficult maneuvers to operate.
Instead of lifting girders up from the ground, the machine takes these enormous sections and drops them into place from above, extending beyond the sections that are already in place, making the process both faster and more precise than using traditional cranes.
580-ton Chinese mechanical beast builds bridges in no time flat!
