A railroad bridge has to be laid over a four-lane federal highway near Flensburg. It is made of steel, 46 meters long, eight meters wide, over three meters high and weighs 267 tons. Two mobile cranes are needed for this. They weigh over 100 tons and can lift up to 1,000 tons. But these extreme weightlifters first have to be assembled themselves, which is why heavy transports bring the individual parts of the cranes to the construction sites. The report shows how they are assembled and used.
