KEMROC EK 160_800 Chain Cutter in Urban Trenching Project.
Mounted on Kobelco SK380 | Cutting Limestone in Dubai, United Arab Emirates.
In Dubai’s demanding construction landscape, precision and efficiency are non-negotiable. For a recent pipeline trenching project, contractors turned to the KEMROC EK 160_800 chain cutter, mounted on a Kobelco SK380 excavator, to deliver exact and efficient trenching through limestone rock with a compressive strength of 50–60 MPa. The result: a perfectly profiled trench: 3 m deep, 1.5 m wide, and 35 m long, completed with unmatched accuracy and speed.
The EK 160_800 chain cutter is one of KEMROC’s most advanced excavator trenching attachments, designed specifically for rock trenching, pipeline installation, and foundation excavation. Its dual cutting drums connected by a central chain ensure a clean, uniform trench bottom, eliminating the “ridge” typically left by twin-drum cutters. This makes it ideal for utility and pipeline projects where exact trench geometry is critical for pipe bedding and backfilling efficiency.
High Performance in Tough Conditions
Mounted on the Kobelco SK380, the chain cutter EK 160_800 showcased exceptional cutting force and stability, powered by precision German engineering. The limestone’s strength (50–60 MPa) posed a significant challenge, but the 17 mm pick-equipped chain cutter maintained consistent penetration and cutting efficiency throughout the project. KEMROC attachment’s optimized torque and hydraulic power transfer delivered continuous production, minimizing idle time and reducing the need for multiple passes.
The contractor reported a notable improvement in trenching productivity, citing smoother operation, less wear and tear, and lower maintenance costs compared to traditional trenchers or hydraulic breakers. With KEMROC’s solution, the team avoided over-excavation, achieving the required trench dimensions precisely, a crucial advantage for urban and high-value infrastructure sites like Dubai.
Why KEMROC Was the Smart Choice for Urban Trenching Project?
The decision to select KEMROC over other brands came down to 5 main factors: higher productivity, lower maintenance, low vibration, low sound, and precision cutting. KEMROC EK 160_800 chain cutter not only reduced downtime but also ensured predictable results, enabling efficient pipe installation, and reducing backfilling material costs. Contractors highlighted the advantage of controlled trench profiles, which simplified subsequent phases of the project.
In urban areas, especially near residential villas, low vibration and minimal noise were crucial. KEMROC’s cutting technology allowed the contractor to work efficiently without disturbing nearby residents, a major advantage in densely populated neighborhoods. The reduced sound levels and low vibration performance ensured compliance with environmental standards and created a safer, quieter working environment for both operators and the community.
Furthermore, the robust design and long-lasting picks contributed to lower tool consumption, offering excellent cost-per-meter performance. With KEMROC’s proven advantages, choosing KEMROC chain cutter for this pipeline and Urban trenching project was a smart and strategic decision by the contractor.
Conclusion: Smarter Urban Trenching for Modern Infrastructure
This project stands as a testament to the efficiency and precision that define KEMROC’s range of chain cutter trenching attachments. The EK 160_800 chain cutter, paired with a Kobelco SK380 excavator, proved to be the ultimate combination for smart rock cutting trenching in medium-hard limestone, delivering speed, accuracy, and operational reliability.
With KEMROC chain cutters, contractors gain more than an attachment, they gain a trenching technology German-engineered for performance and savings. As Dubai continues to expand its underground infrastructure, solutions like the KEMROC chain cutters will remain essential excavator attachment for achieving consistent, high-quality results in excavator trenching and pipeline construction. On top, KEMROC chain cutter’s low sound and low vibration made it the optimum choice for sensitive underground conditions, minimizing disturbance to nearby utilities, structures, and nearby community – a frequent requirement in urban Dubai projects.
