Lötschberg Base Tunnel
Switzerland
On the Lötschberg Base Tunnel in Switzerland, Doka supplied several adaptable tunnel formwork travellers for complex sections such as the 4 jet-vent tunnels and the 275m long broadening zone. The fact that the system components used here are all rentable, and that the system is so adaptable and easy to operate, were a crucial advantage.
