Crane specialist EGGER takes over bridge lift

Old iron bridge being renovated

Two hours of work in around one minute: the 120-year-old Sitter Bridge is excavated for the first time for extensive renovation work. This measure is part of the renewal of the railroad line between Gais and Appenzell.

With impressive precision, the 50-metre long, 4.35-metre wide, 7.65-metre high and 100-tonne bridge was lifted out of its mountings using a tandem lift of two cranes and placed on a meadow next door for the renovation work.

A 650-tonne pneumatic crane and a 250-tonne crawler crane were used.

The renovation work starts immediately and in October the bridge is raised again using the same procedure. This will ensure that they continue to function for decades to come.

The Hawker Hunter aeroplane is safely back at the Hunter association Obersimmental
Until a few years ago, the former Hunter fighter aircraft of the Swiss Air Force were among the highlights at airshows in Switzerland. So was the Papyrus Hunter. The jet has been looked after and maintained by the Hunter association Obersimmental for many years. Unfortunately, the increasingly strict regulations became its downfall. In autumn 2023, the Papyrus was flown over to Altenrhein for its annual inspection. It was no longer allowed to take off from there.
