Launching 1,100te Bridge, Hennigsdorf, Germany
ALE launched a 1,100te railway bridge over the Oder Havel Canal in Hennigsdorf, Germany in a complex installation that included a combination of land, rail and water transport.
In the first phase of the transport, the 101m bridge structure was lifted 10m using four gantries, each with a 500te strand jack. The bridge was then skidded transversely 24m over railroad tracks. In order to support the skid ways, ALE installed bridging beams, supported by jacks, to compensate for the expected settlement in the foundations. Once the bridge was centred on the rail tracks, it was jacked down 1.5m onto 32 rail bogies. The bridge then needed to be transported the 500m to the quayside by rail.
