Kemroc EK Series
EK-SERIES
Kemroc Chain Cutters
Introducing the groundbreaking KEMROC EK series, the first of its kind on the market. Engineered for excavators ranging from 2 to 70 tons, these attachments excel at cutting stone with a uniaxial compressive strength of up to 120 MPa. They offer efficient, vibration-free operation, ensuring precise excavation of narrow trenches with the perfect trench profile every time.
The kemroc engineering qualty guarantee
Minimal wear on the excavator is achieved because the operation method mimics that of using a bucket, thereby eliminating the need for swing motion.
It requires approximately 40% less energy compared to an equivalent drum cutter that lacks a chain between the drums.
