KEMROC EK 160 Chain Cutter – trenching in Greece.
Caterpillar 345BL | Cutting limestone in trenching project.
In the Peloponnese region of Greece, a long-term infrastructure project required extensive trench excavation for electrical cable installation serving a large wind farm development across mountainous terrain. The project involved hundreds of kilometers of trenching through limestone formations, demanding an efficient excavator trenching solution capable of delivering consistent trench dimensions, high productivity, and minimal material handling challenges.
To meet these requirements, the contractor deployed the KEMROC EK 160 chain cutter mounted on a Caterpillar 345BL excavator. Compared with traditional rock breakers, the KEMROC chain cutter significantly outperformed impact tools in both cubic meter output and linear trench production. While rock breakers typically create wider and irregular trenches, the chain cutter produced precise, straight trenches with the exact required width, ensuring accurate trench profiles and reducing unnecessary excavation.
Another key advantage was the quality of the excavated material. The chain cutter generated fine, crushed material suitable for immediate reuse as backfill, eliminating the need to transport large rock fragments away from the job site. This was particularly important given the narrow mountain access roads within the wind farm area, where heavy cranes and low-bed trucks needed smooth and stable surfaces to operate safely. The controlled cutting process produced a level trench with consistent slopes, improving site accessibility and operational efficiency.
The KEMROC chain cutter also proved superior to conventional trenchers for this specific application. Due to the challenging terrain and narrow site conditions, traditional trenching equipment would have been too heavy and difficult to maneuver on the mountain roads. Additionally, trenchers typically discharge excavated material to the sides of the trench, which in this case would have deposited large volumes of rock on private land areas containing trees and vegetation, creating environmental and logistical complications.
By contrast, the KEMROC chain cutter attachment allowed operators to maintain full control over the excavated material. The crushed output could remain directly within the trench corridor, already profiled and leveled, ready for backfilling without additional material handling. This approach minimized site disturbance, reduced the need for hauling and cleanup operations, and streamlined the entire trenching process.
Overall, the deployment of the KEMROC EK 160 chain cutter delivered substantial operational and economic advantages. The precise trenching capability, controlled material output, and reduced equipment logistics significantly lowered the cost per excavated linear meter, making KEMROC chain cutter the most efficient and practical solution for this large-scale wind farm infrastructure project in Greece.

Efficient Excavator Trenching in Hard Limestone
The KEMROC EK 160 excavator chain cutter proved to be the ideal trench cutter solution for this demanding application. Designed as a high-performance chain cutter attachment, the EK 160 enabled efficient rock cutting trenching while maintaining accurate trench profiles.
Mounted on the Caterpillar 345BL, the excavator trenching attachment allowed the contractor to excavate narrow trenches directly through the limestone with controlled cutting geometry. Unlike conventional excavation tools, the chain cutter trenching attachment uses a continuous cutting chain equipped with round attack picks, enabling gradual material removal and smooth trench walls.
The use of an excavator chain cutter trench system provided several advantages on the job site. The controlled cutting process minimized over-excavation and ensured uniform trench dimensions, which was essential for the installation of utilities and underground infrastructure. In addition, the KEMROC chain cutter enabled precise profiling of the road sides, eliminating cracks and creating stable, clean surfaces that helped secure the trench walls and improve overall ground stability along the excavation corridor.

Higher Productivity and Lower Maintenance
One of the key reasons the contractor selected the KEMROC chain cutter over alternative solutions was its ability to deliver higher productivity while reducing maintenance requirements. Compared to traditional trenchers and other excavation methods, the chain cutter attachment provided a more efficient cutting process with fewer interruptions for tool maintenance.
Additionally, the robust engineering of the KEMROC EK 160 excavator chain cutter ensured reliable performance throughout the project’s 18-month duration, maximizing machine utilization and reducing downtime.
Optimized Material Handling on Site
Another important benefit of the chain cutter trenching attachment was the quality of the excavated material. The rock trenching process produced fine, reusable backfill material, which could be directly reused during trench backfilling operations. This significantly reduced the need for importing additional material and helped optimize overall project costs. Furthermore, compared to conventional trenchers that often extract material to the side of the trench, the KEMROC excavator trenching attachment minimized side spoil accumulation. This was particularly beneficial for working in confined project areas and agricultural land in the Peloponnese region, where maintaining a clean work zone was essential.

Precision Rock Cutting for Infrastructure Projects
By combining the KEMROC EK 160 chain cutter with the Caterpillar 345BL excavator, the contractor achieved a highly efficient rock cutting trenching solution capable of delivering consistent results in hard limestone. The excavator chain cutter trench system provided precise trench geometry, high productivity, and improved material management, making it a reliable choice for demanding excavator trenching applications.
This project highlights how modern chain cutter technology can significantly improve the efficiency of rock trenching operations in infrastructure projects. With its proven performance, the KEMROC EK 160 chain cutter attachment continues to demonstrate why it is a preferred solution for contractors seeking precision, productivity, and reliability in challenging ground conditions, while also significantly reducing the cost per excavated linear meter.
