| The Hartlsgraben - Bridge lies on the B146 between Admont and Hieflau in Styria, Austria. As the renewal cost would been too high, the decision came for the new erection of the bridge, with contractor Massivbau GmbH (Klagenfurt Carinthia, Austria). The form traveller from Wito, in connection with the Doka - large area formwork Top50, made best results. Special about this project is the use of only 1 from traveller for erecting one cantilever aren from each side. To prevent the abutement from lifting - off, a heavy concrete girder was built into the end of cross section as a counterweight. By this measure the system with one cantilevering arm from each side had been able to be produced without any auxiliary supports or additonal costs. |
