Second Gotthard road tunnel tube: Drill head lifting


Friday, 4. October 2024

The cutterhead of the 12.3-metre-diameter tunnel boring machine for the main drive was successfully lifted into place. In a confined space, the ARGE secondo tubo managed to lift the 360-tonne cutterhead using a gantry crane and mount it on the TBM's main drive. IUB Engineering AG, as the lead company of IG-2G-BN, Construction Management North, wishes the ARGE secondo tubo continued success!
