EK 150 | Chain Cutter Attachment for Heavy Excavators
High-Efficiency Cutting with Reduced Energy, Wear, and Operating Costs
- Verified cutting capability in stone and concrete up to 100 MPa uniaxial compressive strength
- 40% lower energy consumption
- Operates underwater without modification
The EK 150 Chain Cutter attachment for heavy excavators is designed for contractors who need high cutting performance without paying the price in energy loss, machine wear, or unnecessary material handling. Positioned within the EK Chain Cutters range, EK 150 applies a continuous chain cutting principle that fundamentally changes how material is removed compared to conventional rotary drum cutters.
Mounted on 35–50-ton excavators, EK 150 eliminates one of the most inefficient aspects of drum cutting: the uncut material left between the drums. Thanks to its continuous central cutting chain, material is cleared automatically from the cutting zone. This removes the need for lateral swinging movements, allowing the attachment to stay engaged with the ground and convert hydraulic power directly into productive cutting.
With a verified cutting capability in stone and concrete up to 100 MPa uniaxial compressive strength, EK 150 chain cutter attachment for heavy excavators combines heavy-duty performance with measurable efficiency gains—making it a practical solution for long-duration excavation projects where operating cost control is as important as cutting power.

Why Choose the EK 150 Chain Cutter Attachment for Heavy Excavators?
Up to 40% Energy Savings Through Continuous Cutting
EK 150 chain cutter delivers approximately 40% lower energy consumption compared to equivalent rotary drum cutters without a central chain. By removing material continuously between the drums, hydraulic energy is no longer wasted on repeated swinging or re-cutting already loosened ground.
Reduced Wear on Excavator Swing Components
Because EK 150 does not require side-to-side swinging to clear material, mechanical stress on the excavator’s swing gear, slew ring, and swing drive is significantly reduced. This translates directly into lower long-term maintenance costs and improved machine availability.
Cost-Efficient Excavation Output
The cutting process produces fine-grained spoil, which can be reused immediately as backfill. This reduces the need for material transport and minimizes the purchase of external fill material—lowering total project costs per meter excavated.
• Maximum torque: approx. 30,300 Nm • Operating pressure: up to 400 bar Rather than applying force in short, inefficient bursts, EK 150 uses available torque steadily, maintaining consistent penetration in hard ground and concrete.
• Recommended oil flow: approx. 280–320 l/min • Excavator class: 35–50 t This configuration allows EK 150 to operate within the optimal hydraulic range of heavy excavators during extended shifts without performance drop.
When used for trenching, EK 150 cuts only the width that is structurally necessary, producing clean trench profiles. This minimizes excess excavation, reduces spoil volume, and lowers transport and reinstatement costs.
The continuous cutting action breaks material into uniform, fine-grained particles, making the output suitable for direct reuse as fill and improving overall site logistics.
Main Applications of the EK 150 Chain Cutter Attachment for Heavy Excavators
Heavy Trenching & Pipeline Installation
EK 150 chain cutter attachment for heavy excavators produces deep, narrow trenches with accurate profiles, supporting efficient installation of pipelines and utility corridors while minimizing excavation width.
Mining of Medium-Hard Materials
The attachment supports selective mining operations in materials up to 150 MPa UCS, particularly where drill-and-blast methods are restricted or not permitted.
Tunneling & Profiling Works
EK 150 is suitable for precision cutting and profiling in confined excavation zones, supporting controlled shaping rather than uncontrolled breakage.
Underwater and Submerged Projects
Like the rest of the EK range, EK 150 chain cutter attachment for heavy excavators operates underwater without modification, making it effective for dredging, harbor construction, and submerged excavation up to 30 meters depth.
FAQs – EK 150 Chain Cutter Attachment for Heavy Excavators
What size excavator is the EK 150 designed for?
EK 150 chain cutter is recommended for heavy-duty excavators between 35 and 50 tons.
Can EK 150 cut reinforced concrete or hard rock?
Yes. It is designed for stone and concrete with a compressive strength up to 100 MPa UCS. For materials up to 140 MPa, EK 220 or DMW solutions are available.
Does EK 150 chain cutter require additional maintenance compared to other cutters?
No. While other cutters may offer simpler maintenance, EK 150 chain cutter attachment for heavy excavators uses robust bearings and protected hose routing to ensure long service life under demanding conditions.
How does EK 150 reduce overall project costs?
By cutting only the minimum required width and producing reusable fine-grained spoil, EK 150 reduces transport costs, disposal volumes, and the need for purchased fill material.
