GU50-SC Sawmill Machine for Tunnels

Chain Saw Model GU50-SC is a compact version for tunnel extraction work. By setting the cutting depth in automatic mode the machine makes vertical and horizontal cuts against the tunnel face.

It is self-propelled on a track and radio-controlled, and hence completely autonomous in its movements. Only one operator is sufficient to operate the machine. This model can run cuts up to 1.7 metres in depth.
