They are efficient and vibration-free attachments for the excavation of deep narrow trenches with the optimal trench profile. Trench width starts from 370 mm without a maximum limit. Another application is mining of medium hard minerals with compressive strength from 15 to 60 MPa, where drill and blast is not possible.
EK chain cutters reduce wear and tear on the excavator swing gear. In addition, they give a 40% energy saving for equivalent production rates compared to conventional rotary drum cutters without the cen
