PATENTED CUTTING ATTACHMENT; REDUCES WEAR & TEAR ON THE EXCAVATOR SWING GEAR AND SAVES ENERGY
THE EK RANGE OF CHAIN CUTTERS IS THE FIRST OF ITS TYPE ON THE MARKET. DESIGNED FOR USE ON EXCAVATORS FROM 1.5 TO 70 TONS AND THEY ARE IDEAL FOR CUTTING ROCK WITH A UNIAXIAL COMPRESSIVE STRENGTH UP TO 140MPa.
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.
The continuous chain driven by the cutter drums removes the material automatically from the space between the cutter drums, As a result, KEMROC chain cutters excavate trenches no wider than absolutely necessary. With standard drum cutters, the need to remove this material on technical grounds always results in trenches wider than the cutter but keeping trenches to the minimum width possible saves unnecessary transport costs for removal of cut material and fill material becomes cheaper. The material produced by the chain cutter is fine grained and is ideal for use as fill.
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 central chain.
