The mobile bridge allows traffic to flow without interruption while work proceeds underneath.
The complete ASTRA bridge material was collected at the Rothrist storage yard in Switzerland. The site is located within the Wiggertal motorway triangle and is therefore strategically located for quick access to future motorway roadworks.
As the press and experts met, the bridge was assembled in two convoys. The first unit consisted of the complete ramp portals for the entrance and exit as well as a straight portal. The second group consisted of eleven straight portals and was used to programme and then test the satellite navigation.
Endurance test with a low bed semi-trailer combination
During the celebration, the guests had the opportunity to drive across the bridge with their own cars. After that, a test was performed as a premiere with a heavy load combination, for which the Senn company provided its Faymonville CombiMAX as a 2+4 with excavator deck. This demonstrated that the gradients and transition radii of the mobile bridge had been carefully selected so that even such a long and extremely low vehicle can drive over it without any problems.
The complete ASTRA bridge was used for the first time in early April. Senn cooperated here once again by providing its Faymonville CombiMAX combination for the transport of the Cometto ramp portal with the drive-on tongue.
