Roth-Waagner bridge device
The Roth-Waagner bridge device , also known as the Roth-Waagner temporary bridge system or RW device for short , was a transportable steel truss bridge that could be assembled from pre-assembled individual components and used as a temporary bridge for heavier and heaviest loads up to temporary bridges for railways in the military as well as in the civilian area was used.
Shortly before the beginning of the First World War it was built in Austria-Hungary by the building officer Ing. Friedrich Roth, member of the Austro-Hungarian Railway Regiment, together with the bridge construction company R. Ph. Waagner, L. u. J. Birò and A. Kurz developed and used on a large scale in the following war by the Austrian and German armies.
The system was based on a field width of 3 m and 4 m high beams. It could be two-walled or three-walled and single-storey or two-storey with 8 m high beams.
The Roth-Waagner system was z. B. used for the
- Old Belgrade railway bridge over the Save in Belgrade , the 96 m wide central opening of which was assembled in 7 days,
- the railway bridge over the Vistula near Ivangorod (around 90 m span),
- the bridge over the Olt and the Caracau Viaduct in Romania,
- the great Salcanobrücke over the Isonzo , which was spanned in the cantilever and
- the Mainbrücke Volkach (1947–2011), part of the bridge was installed as a memorial on the western abutment.
After the First World War, the RW bridge device was used several times as a supporting structure for railway bridges of the Austrian Federal Railways . During the Second World War it was used extensively in the armies of both countries and after the Second World War it was used to restore blown bridges, but was replaced by the more modern SKR ( Schaper-Krupp-Reichsbahn ) device.
After the war, the RW device was z. B. used under Soviet supervision for the repair of the Mauterner bridge over the Danube, where it forms the southern half of the bridge to the present day.
