Maritime bewegliche Brücken

Maritime moveable bridges - Steel linkspans for Rostock Port and Lübeck Port Authority.

Linkspans play a key role within the increasing RoRo traffic in sea trade. The particular requirements related to design and execution, also with regard to very short planning processes of only one year from the start of planning until contract awarding, indicate that large multi-disciplinary projects can also be accomplished in Germany. The interdisciplinary cooperation in civil engineering, hydraulic engineering, electric and hydraulic planning forms the basis for a fast realization of such construction projects. The specific technical requirements and solutions, in particular for steel bridge construction, are demonstrated using the double-deck linkspans in Rostock and Lübeck as examples. The main focus of this essay based on the kinematic boundary conditions, the specific load situations as well as on the typical harbor load models in connection with the weight-optimizing construction method. The question will be answered whether linkspans are counted among complex bridge structures or machine constructions.
