Blankenfelde op rolletjes
A large-scale renovation project is underway in Berlin on the Dresdner Bahn, one of the most important railway connections in Berlin. The bridge team from Wagenborg Nedlift was there!
Renovation of the Dresden Railway
The renovated Dresdner Bahn will soon connect Berlin city centre quickly and directly with Berlin Brandenburg Airport. And once all the work has been completed, the journey time on the Berlin–Dresden route will be reduced by no less than 45 minutes.
But before that happens, there is a lot to be done on this very busy 16-kilometre stretch of track. For example, a completely new double track is being laid alongside the existing connection. In addition, all nine level crossings are being replaced by railway bridges or underpasses, and another nine railway bridges are being renovated or expanded. A mega project of the highest order!
Bridge team
The bridge specialists at Wagenborg Nedlift were called in to install the new railway viaducts near Blankenfelde.
The heaviest bridge, weighing 183 tonnes, was unloaded in sections at the nearby construction site, transported to the project location using SPMTs, and installed there.
Electric trolley system
The bridge team utilised a sustainable horizontal displacement technique for this purpose. Instead of working with the traditional, hydraulically driven, sledge system, the team opted for ETR, an electric trolley system.
This ETR trolley system can move loads weighing up to approximately 600 tonnes horizontally along a guided rail system. The trolley system is electrically powered, making it emission-free and low-noise. Furthermore, as no hydraulics are involved, much less equipment needs to be transported to the project site. An environmental incident due to oil leakage is also ruled out.
On wheels
The trolley system not only scores better in terms of sustainability, but its technical properties also offer advantages over conventional sledge systems. The movements of the load are more stable thanks to the continuous movement and the ability to precisely control the travel speed, including acceleration and deceleration. Perfect for the installation of the railway viaduct in Blankenfelde.
This operation went smoothly, both literally and figuratively!
