Conning tower

The foreign word superstructure called - as a counter-concept to infrastructure - pavements such as all types of buildings ( warehouses, office and residential buildings, etc.) and all types of attached or halbbeweglichem equipment ( cranes, ramps, etc.). This can be seen in the photograph, the Kai is part of the infrastructure of the port and must be present, it can not be moved. The cranes are mobile, they can move from one point to another, or to be transported. So you belong to the superstructure of the port.
