EK 160 | Heavy Excavator Chain Cutter
Built for Maximum Resistance and Continuous Heavy-Duty Performance
- 40% lower energy consumption
- 120 MPa uniaxial compressive strength
- Operating within a recommended oil flow of 290–330 l/min
- Durability under abrasive and high-resistance contact conditions
The EK 160 Heavy Excavator Chain Cutter is designed for operations where ground resistance remains consistently high and attachments are required to perform under sustained mechanical stress. Positioned within the EK Chain Cutters range, EK 160 shifts the focus toward endurance under load, rather than simply production volume or energy efficiency.
Mounted on 35–50 ton excavators, EK 160 operates at a controlled speed of 60 rpm, delivering up to 34,000 Nm of torque and 80 kN cutting force. This configuration allows the attachment to maintain stable chain engagement in materials reaching 120 MPa uniaxial compressive strength.
Instead of relying on aggressive speed, EK 160 combines structural mass (3,650–3,800 kg) with torque reserve to ensure controlled, repeatable cutting behavior in high-resistance environments over extended operating cycles.

Why Choose the EK 160 Chain Cutter?
Engineered for 120 MPa Material Resistance
With a verified cutting capacity up to 120 MPa UCS, EK 160 is positioned for applications where lower-capacity attachments reach their mechanical limit.
High Torque Stability Under Load
Delivering 34,000 Nm at 380 bar, EK 160 chain cutter provides the torque reserve required to maintain chain motion without stalling in dense ground.
Endurance-Oriented Hydraulic Design
Operating within a recommended oil flow of 290–330 l/min, EK 160 is calibrated for sustained heavy-duty cycles rather than short cutting bursts.
Reduced Shock Compared to Impact Tools
The continuous cutting principle distributes force gradually, reducing sudden load spikes that typically affect excavator structures when using breakers.
• Maximum torque: 34,000 Nm • Maximum cutting force: 80 kN • Operating pressure: up to 400 bar These values support stable penetration in high-density rock and reinforced materials.
• Recommended rotation speed: 60 rpm The lower rotational speed ensures consistent chain engagement without excessive vibration or mechanical stress.
• Weight: 3,650–3,800 kg • Gearbox width: 700 mm • Cutter drum diameter: 850 mm The attachment mass and geometry contribute to stability during high-load cutting operations.
• Pick box: PH 32 HD • Drum picks: 44 / 48 / 56 • Chain picks: 63 • Standard pick: ER 19/75/70/30 Q The pick configuration is engineered for durability under abrasive and high-resistance contact conditions.
Main Applications of the EK 160 Chain Cutter
High-Resistance Rock Excavation
Designed for continuous excavation in rock formations approaching 120 MPa UCS, where torque stability is critical.
Controlled Concrete & Structural Removal
Suitable for cutting thick concrete and reinforced structures where impact tools would generate excessive vibration.
Heavy Civil & Industrial Excavation
Applicable in projects requiring consistent excavation performance under sustained mechanical load.
Underwater Operations
Like the rest of the EK range, EK 160 operates underwater without modification, maintaining performance under submerged conditions.
FAQs – EK 160 Chain Cutter
What excavator class is required for EK 160 chain cutter?
EK 160 is recommended for excavators between 35 and 50 tons with appropriate hydraulic flow capacity.
What material strength can EK 160 handle?
The attachment is rated for materials up to 120 MPa UCS.
How is EK 160 different from EK 150?
EK 160 prioritizes maximum resistance capability and torque stability, while EK 150 focuses more on production efficiency and cost optimization.
Can EK 160 chain cutter operate continuously in hard ground?
Yes. Its torque reserve, structural mass, and hydraulic configuration are designed for sustained heavy-duty operation.
How does EK 160 chain cutter achieve lower energy consumption?
By using a central chain to remove material between the drums automatically, EK 160 eliminates inefficient swinging movements and reduces wasted hydraulic energy—resulting in up to 40% energy savings.
