The PERI VARIOKIT solution for the cantilever method is a combination of stable, specifically developed system components for the main load transfer and VARIOKIT standard parts for the design of formwork, work scaffolding and platforms, as well as adjustment to the geometry of the cross-section.
Customized solution Load-optimized, rentable adaptation to the bridge geomety due to the construction kit principle
Easy and simple Jobsite-compliant and efficient application with standardized modular construction system
Safe Modular working platforms and access means to all working areas through a compatibility to the PERI UP scaffolding system
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 270 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 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.
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.
