It’s almost 44 metres in length, and it’s one of the oldest swing bridges in Germany. The railway bridge in Warnemünde can once again be reliably rotated through 90 degrees – all thanks to the steel workers from Karstädt in Brandenburg. The SCHORISCH team completely renewed the rotational drive system and the bearings as part of contract awarded by the Hanseatic City of Rostock.
The Baltic seaside resort’s swing bridge was brought into service in 1903, and it’s not the first listed technical monument that the engineers and craftsmen from Karstädt have renovated. This is because they are the recognised specialists for the renovation of land- and water-based old steel structures.
“The renewal of such structures which are showing their age requires precision planning as well as considerable expertise and experience, and the welding that is involved is crucially important. In Warnemünde too – where the total span of the railway station bridge is 41.50 metres – the work was carried out with the utmost precision.
The rotating section by itself is 29.5 metres long. With a width of 7.10 metres the steel giant weighs in at an impressive 56 tonnes as measured by load cells. In order to carry out the renovation and welding operations hydraulic presses were used to raise the bridge by 65 centimetres, and it was then placed on support chocks.
