An ERC 1500 revolving rotary drum cutter is used to drive a railway tunnel in a weak to strong rock (30–40 MPa) in India. 
The horse-shoe shaped tunnel is 8 m wide and 9 m high.  One metre depth is cut across complete tunnel cross section in two hours i.e. approx. 32 m3/hr.


No two jobsites are alike.
The productivity depends on the material characteristics or rock hardness, the settings and condition of the carrier unit, the technical and wear condition of the attachment and the operator skills, as well as a couple of other factors. The given figures can vary based on different conditions. We reserve the right to change technical data without further notice.
