Construction of the Scherkondetal bridge near Weimar
The bridge is a semi-integral structure with a solid cross section and spans of up to 44 meters. The structure carries the railroad line over a river and a nature conservation area. One of the prime demands was therefore to minimize the environmental impact. We were entrusted with the planning, supply, erection, and relocation services for a rentable movable scaffold that ran beneath the superstructure and was used for span-by-span construction.
For shifting we used crane-independent self-launching brackets. No ground-supported lifting gear was required to relocate the pier scaffolds. By fixing the self-securing launching equipment of the movable scaffold on reaching the concreting position, we were able to achieve the structurally beneficial pre-curvature of the bridge piers.
