A 30-metre-long, melon-yellow steel arch bridge over Heerstraße in Duisburg now connects the city centre with Rheinpark. In future, it will provide pedestrians and cyclists with a direct route from the main railway station to the Rhine. The project is impressive not only in terms of functionality but also visually.
However, the steel constructor faced a typical but critical challenge when installing the spherical bearings: welding distortions on the base plates resulted in tolerance deviations of up to 1.5 mm. This is too much to ensure precise bearing support. That is why our gap compensation material MM1018 – The Liquid-Shim® – was used. Applied on site, the polymer metal reliably compensated for the unevenness and created a force- and form-fitting connection: resilient, precise and durable.
A particularly challenging aspect was the very tight schedule: the work took place shortly before the planned lifting of the bridge, which meant that every move had to be perfect.
Thanks to good coordination with MWM, the work was completed smoothly.
