EK RANGE - CHAIN CUTTERS

The EK range of chain cutters are the first of their type on the market. Designed for use on excavators from 1.5 to 70 tonnes, they are ideal for cutting stone with an uniaxial compressive strength up to 120 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 80 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. 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 percent energy saving for equivalent production rates compared to conventional rotary drum cutters without the central chain.

FEATURES
  • Minimal wear on excavator

  • Needs approx. 40 percent less energy than equivalent drum cutter

  • Range of cutting widths available

  • Fine grained cut material

  • Low noise and vibration levels

  • Works underwater without need for modifications

APPLICATIONS
  • Trenching and pipeline work

  • Mining of soft to medium hard minerals

  • Can also be used for concrete renovation, profiling, underwater excavations and tunnelling
