This amazing video shows a giant machine called the SLJ900/32 building a bridge in China. The SLJ900/32 is built by the Beijing Wowjoint Machinery Company and is an impressive 91m long, 7m wide, 9m tall, and weights a staggering 580 tons. You can sense its size in the video below, when you see workers scale down it to begin work.
It’s lays new bridges one section at a time, progressing gradually across support girders. The behemoth of a machine is a perfect example of how China’s economy and construction industry is booming and requires giant feats of engineering to keep up with the growth.
