EK 60 | High-Output Excavator Chain Cutter
Powerful Trenching Attachment for 12–17 Ton Excavators
- Achieves a cutting depth of up to 1,600 mm
- Operates with low vibration and reduced noise
- Cuts Soil, asphalt, concrete, and rock formations up to 50 MPa UCS
- Developed for high-performance trenching and controlled excavation without impact
- Delivers smooth material removal
The EK 60 High-Output Excavator Chain Cutter is part of the EK Chain Cutters range, KEMROC’s patented chain cutting system developed for high-performance trenching and controlled excavation without impact. The EK range replaces conventional breaking methods with a continuous cutting principle, enabling precise trench geometry, predictable cutting performance, and significantly reduced vibration.
Designed for excavators in the 12–17 ton class, EK 60 represents a major step up in cutting power and productivity. Instead of relying on percussive force that creates noise, vibration, and uncontrolled fracturing, the patented EK cutting chain delivers smooth material removal, low-noise operation, and consistent trench profiles—even in demanding ground conditions.
With the capability to cut soil, asphalt, concrete, and soft to medium-hard rock formations up to 50 MPa UCS, KEMROC EK 60 chain cutter is ideally suited for infrastructure trenching, deep utility installation, road construction, and heavy renovation works where output, depth, and reliability are critical.

Why Choose the EK 60 Chain Cutter?
High Output for Demanding Trenching
With a rated power of 60 kW and a maximum torque of 11,000 Nm, EK 60 is engineered for high material removal rates in compact and abrasive ground conditions—significantly increasing productivity compared to smaller chain cutters.
Deep and Wide Trenching Capability
EK 60 chain cutter achieves a cutting depth of up to 1,600 mm and is available with 500 mm or 600 mm cutting widths, allowing contractors to adapt the attachment to varying trench requirements and utility dimensions.
Low Vibration & Low Noise Operation
Despite its high output, EK 60 operates with low vibration and reduced noise, making it suitable for infrastructure projects near roads, buildings, and existing services.
• Maximum torque: 11,000 Nm at 400 bar • Maximum cutting force: 36.7 kN This level of performance allows EK 60 to cut efficiently through dense soils, reinforced concrete layers, and rock formations up to 50 MPa UCS without performance loss.
• Recommended oil flow: 130–160 l/min • Maximum oil flow: 220 l/min • Maximum operating pressure: 400 bar These parameters ensure reliable performance on modern excavators with high-capacity hydraulic systems.
• Pick box type: PH 22 • Number of picks on cutter drums: 40 or 60 (depending on configuration) • Number of picks on cutter chain: 53 • Standard pick: ER 15/46/38/22 C The robust pick configuration is optimized for abrasive materials and extended service life, even under continuous operation.
With a weight between 1,250 and 1,300 kg, EK 60 chain cutter provides excellent stability on 12–17 ton excavators, ensuring controlled operation and reduced mechanical stress on the carrier.
Main Applications of the EK 60 High-Output Excavator Chain Cutter
Deep Infrastructure Trenching
Ideal for large-diameter pipelines, district heating lines, and deep cable routes, EK 60 delivers accurate, deep trenches with uniform geometry.
Road Construction and Rehabilitation
EK 60 chain cutter efficiently cuts through asphalt layers and concrete road structures, preparing surfaces for reconstruction without damaging adjacent areas.
Selective Excavation in Rock and Concrete
The controlled cutting process allows precise removal of material in rocky or reinforced ground, reducing overbreak and material mixing.
Trenching in Medium-Hard Rock
Designed for formations up to 50 MPa UCS, EK 60 performs reliably in limestone, sandstone, compacted rock, and similar materials where conventional trenching tools struggle.
