For building bridges over rivers or lakes, floating cranes are needed to lift over 1000 tons of weight. In this video we will see the largest floating crane in the world that was built in Japan and can raise up to 4100 tons.
It’s called Kaisho and it’s a very important machine built by the Japanese. Usually 2 or 3 such cranes work in parallel and thus can raise very heavy loads up to 10,000 tons.
Take a look at this floating crane.
