The new arch bridge weighing more than 660 tonnes forms a key component of one of the largest infrastructure projects in the region, connecting the inner city of Köthen with important arterial roads. In addition, the bridge is elevated, making it possible for the catenaries on the important Halle - Magdeburg rail link to be adapted in accordance with the new requirements.
In the past few months, large structural components of the bridge were transported from the construction workshop to the construction site next to the railway tracks. There, the steel construction specialists assembled the bridge into a colossus measuring no fewer than 73.0 metres long, 18.0 metres wide, 15.0 metres high and weighing 660 tonnes
In the meantime the engineers of Wagenborg Engineering had been studying the best way to install the bridge across the seven (!) railway tracks. This operation had to be carried out during a brief stoppage on the weekend to keep train traffic delays at a minimum.
The engineers from Wagenborg Engineering opted for the use of a combination of techniques to install the bridge. On one side of the track, where the bridge was assembled at the construction site, SPMTs were used for the transport. On the other side of the track, a 600-tonne crawler crane was ready to take over the end of the bridge. For the horizontal movement across the track, the engineers opted for Wagenborg Nedlift's own developed sliding system. Finally, several jacking systems were used for the vertical positioning.
A complex combination of relocation techniques, calculated and engineered to perfection by the clever minds at Wagenborg Engineering.
