TBM for the tunnel clearance Belchen

Following a welcoming address and the presentation of the cutter head on the gloriously sunny day of 11 November, the invited guests, including representatives from building contractors, construction management, politics and public authorities, were in attendance to celebrate the insertion of the cutter head at the front of the TBM.
With a total weight of 350 tons and a diameter of 13.97 metres, the cutter head is currently the largest in Switzerland.
