Excavator hydraulic milling cutter EK 110

Overview
The EK 110 Infrastructure Excavator Chain Cutter is a multi-purpose chain cutting attachment for civil engineering projects, engineered for 25–32 t excavators. Based on KEMROC’s chain cutting system, the EK 110 provides controlled continuous cutting at 65 rpm with performance suitable for soils, reinforced concrete and rock up to 80 MPa UCS. It is designed for trenching, selective excavation, profiling and concrete renovation in variable ground conditions.

Key benefits

• Reduces energy consumption by up to 40%
• Handles materials with compressive strengths up to 80 MPa
• Designed for low noise and vibration
• Produces narrow trenches with precise profiles
