KDS 30 in a railway tunnel: Cable ducts removed quickly


A KEMROC KDS 30 diamond saw on a compact excavator cuts out concrete cable ducts from the floor of the tunnel to make room for a new tunnel lining.

The Elleringhauser Tunnel in Germany’s Hochsauerland region is being completely renovated. To install new tunnel lining, concrete cable ducts had to be removed from the bottom of the tunnel wall. Specialists from the EET consortium (Max Bögl/Marti DE/Marti CH) chose an 8-tonne compact excavator and a KEMROC KDS diamond saw to cut the concrete ducting into manageable pieces
