VARIOKIT VBC Balanced Cantilever Carriage


The PERI VARIOKIT solution for balanced cantilever construction is a combination consisting of load-bearing, specially developed system components for this building method and VARIOKIT core components to complete the supporting structure. Based on the VARIOKIT Engineering Construction Kit, the rentable system components are quickly available. The bal-anced cantilever equipment can be adapted flexibly to accommodate a wide range of bridge cross-sections and geometries.

Reducing construction time
thanks to concreting sections up to 5.75 m long, as well as high load-bearing capacity and integrated hydraulics

Cost-effective project solutions
by combining practice-oriented and rentable system components based on the VARIOKIT Engineering Construction Kit and project-specific engineering

Safe access solutions
in all conditions due to compatibility with the PERI UP modular scaffolding kit

Technical Details

The balanced cantilever equipment transfers the fresh concrete loads into the supporting structure and moves the formwork from section to section. In order to accommodate the changes in the hollow box cross-section, a formwork solution consisting of VARIO girder wall formwork is used.

  • Concreting section weights up to 300 t using a standard application with two main frames
  • Section lengths up to 5.75 m possible
  • Maximum adaptability for transverse and longitudinal inclinations
  • For use in radii and spiral curves
  • Weight optimization due to a high level of material utilization
  • Exact, dimensionally-accurate concreting results through automatically setting up by means of integrated hydraulics
  • All modules can be re-used without any further processing

The PERI cantilevered construction equipment used allowed easy and quick formwork alignment as well as providing safe working conditions above the railway. With the help of the balanced cantilever carriage, extremely short concreting cycles as well as punctual realization of the project according to plan are possible. Thanks to the cooperation with PERI, the job could be realized in spite of the complicated infrastructure around the structure.

The chosen solution of using VBC Balanced Cantilevered Carriages proved itself to be correct. Thanks to the high flexibility of the system, we could optimize our project so that the workload necessary to pour each segment was as short as possible. It also had a measurable influence on the assumed schedule.

The PERI cantilevered construction solution provided us with many advantages: fast realization due to the well thought-out and easy handling as well as compliance with the required tolerances thanks to the practical formwork adjustment which allowed very accurate construction of the webs. In addition, the compatibility with PERI UP facilitated safe access means and working areas without any extra time and effort - indispensable for the execution of such a project.
