Like a mole through the Gotthard
Engineering | The world´s longest train-tunnel is now open: Our slewing bearings have finished drilling through the Gotthard!
After 17 years of construction time now the main tunnel through the Swiss Gotthard is finally open. Our slewing bearings made in Lippstadt have completed their tireless way through the mountain. The 3-row roller bearings (5 meters diameter, 23 tons) moved the cutterhead of the tunnel drilling machines “Sissi” and “Heidi” 57 kilometers through the St. Gotthard. This means in the future: trains will be able to go from Zurich to Milan in only two and a half hours.
