Berlin U6
Precision Lifting Under Urban Conditions. The Bridge Project U6 Berlin
In this current project on the U6 line in Berlin, the focus was on the controlled movement of an existing bridge structure. As part of a comprehensive refurbishment of the abutments and the bridge construction, the approximately 100-meter-long bridge was temporarily lifted and subsequently lowered back into its final position with high precision.
Eight hydraulic jacks, each with a lifting capacity of 200 tonnes, were used. They operated in pairs, enabling a uniform and load-neutral lifting process of the structure. This approach was crucial to minimize stress within the structure and to ensure that the subsequent work on the bridge bearings could be carried out safely and efficiently.

The hydraulic equipment used enabled millimeter-precise control of both lifting and lowering operations. Especially in dense urban environments, with restricted space and existing infrastructure, this level of precision is a key success factor. The work was carried out in controlled stages, ensuring that all load transfers could be continuously monitored at all times.
The complete refurbishment of the bridge, including the bearings, makes a significant contribution to the long-term serviceability and operational safety of the structure. This project clearly demonstrates how modern lifting technology, experienced planning, and precise execution deliver reliable results even when working on complex existing structures.
