EK SERIES

Chain Cutters

The innovative KEMROC EK range is the first of its type to market. Designed for use on excavators from 2 to 70 tons, they are ideal for cutting stone with a uniaxial compressive strength of up to 120 MPa. These efficient, vibration-free attachments excavate narrow trenches with the optimal trench profile every time.

The KEMROC Engineering Quality Guarantee

The result? Work tools renowned globally for their robust design, high durability, and low maintenance requirements, engineered to withstand harsh working conditions and provide maximum productivity.

REDUCED EXCAVATOR WEAR

Minimal wear on the excavator as the method of operation is similar to using the bucket i.e. eliminates the need for swing motion.

LOW ENERGY CONSUMPTION

Requires ≈ 40 percent less energy than an equivalent drum cutter without a chain between the drums.

SIZED TO SUIT ALL JOBS

A wide range of cutting widths available from 480mm to 1300mm.
