Crane service provider Wiesbauer has lifted a reinforced concrete bridge into position as part of renovations to a railroad overpass in Rottenburg-Kiebingen, Germany.
The company used a Demag CC 3800-1 lattice boom crawler crane to move the piece – which weighed over 400 tonnes – on behalf of Metzingen-based construction company Gottlob Brodbeck.
Wiesbauer project leader Marco Wilhelm noted that rigging the load was complex, owing to its shape, which required the four attachment points to be set up asymmetrically.
He added: “Due to the fact that we had a tight timeframe of only 100 hours to tear down the old bridge and lift the new one into place, it was absolutely crucial not to have any delays in the lift whatsoever.”
Therefore, Wiesbauer carried out a trial lift to ensure its approach would work, before moving the new bridge element smoothly into its final position.
