Higher, stronger, more robust: Crane builders excel with superlatives. Loads are getting heavier and need to be lifted to hard-to-reach places. One of the big crane companies in this country is Knaack Krane in Hamburg. The company currently has about 60 different cranes, the largest of which can lift up to 750 tons. It takes a long way through planning and installation until the machine is used for the first time – the report accompanies the creation of a mega crane.
