TTO, Patent & License Manager, TU Wien at TU Wien

Wien, AT - Österreich, Austria

About

The proposed method will be especially beneficial for bridges with high piers and span length between 50 m and 250 m. The usage of temporary piers enables the expedient application of the balanced lift method for bridges with piers of modest height. The method is also applicable for temporary bridges and lift bridges.

  • Savings in construction materials (20 to 30 % in comparison to balanced cantilever method)
  • Fast vertical assembly of bridge girders and compression struts
  • Concentration of construction at the pier locations
  • Established technologies are available for the lifting or lowering process and the hinges

A pilot was built in Austria in 2020 on the motorway S7 by the Austrian Motorway Operator ASFINAG.
