Talk about heavy equipment! This is the SLJ900/32, a Chinese bridge-building machine. It weighs 580 metric tons and is 91.8 meters long. It carries and installs concrete bridge girders in places where a crane can’t go. This time-lapse video makes it look simple. It can’t be simple.
But at least it’s doable. Watch the guys working with this machine. They hop around hundreds of feet above a chasm, installing tons of concrete, with no safety harnesses. There are two other videos that give a closer look at some of the steps, if you are interested. -via Daily of the Day
