Excavator hydraulic milling cutter EK 100

Overview
The EK 100 chain cutter for medium excavators uses KEMROC’s patented chain cutting technology to provide continuous, non-percussive cutting for precise trench geometry and low vibration. Built for excavators in the 18–30 t class, the EK 100 handles soil, concrete and medium to hard rock up to 80 MPa UCS, enabling consistent production in demanding ground conditions for utilities, pipeline and heavy civil works.

Key benefits

• Cutting depth up to 1,970 mm
• Available cutting widths: 600, 700 or 800 mm
• Continuous chain cutting for clean trench walls and reduced vibration
• Capable of working in formations up to 80 MPa UCS
• Stable machine operation and predictable production rates
