Chain cutters – Patented cutting attachment; reduces wear & tear on the excavator swing gear and saves energy
The EK range of chain cutters are the first of their type on the market. Designed for use on excavators from 2 to 50 tons, they are ideal for cutting stone with an uniaxial compressive strength up to 100 MPa.
They are efficient, vibration-free attachments for the excavation of deep narrow trenches with the optimal trench profile. Trench width starts from 480 mm. Another application is mining of medium hard minerals with compressive strength from 15 to 60 MPa, where drill and blast is not possible.
KEMROC chain cutters excavate trenches no wider than absolutely necessary. The continuous chain, driven by the cutter drums, removes the material automatically from the space between the cutter drums. With standard drum cutters, the need to remove this material on technical grounds always results in trenches wider than the cutter. 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.
