KEMROC EK 160 Chain Cutter in Rock Trenching Project.
Mounted on Komatsu PC 400 | Cutting Limestone in Abu Dhabi, United Arab Emirates.
In the demanding conditions of Abu Dhabi’s construction landscape, precision, performance, and reliability are vital. To achieve fast and accurate rock trenching through tough limestone, a leading contractor in the United Arab Emirates turned to KEMROC for a cutting-edge solution. The selected attachment: the KEMROC EK 160 Chain Cutter, mounted on a Komatsu PC 400 excavator.
The project involved trenching for underground utility installation in compact limestone rock with a compressive strength of 50 MPa (7,252 psi). The trench dimensions were 16 meters long, 4.5 meters wide, and 1 meter deep, requiring a method that could deliver clean, accurate results while minimizing wear and downtime. KEMROC’s excavator chain cutter proved to be the ideal choice, providing outstanding full-face rock cutting trenching performance with exceptional control and efficiency.
Why the Contractor Chose KEMROC for Rock Trenching Project?
After evaluating multiple trenching methods and attachment brands, the contractor selected KEMROC for several decisive reasons:
- Lower maintenance and higher utilization compared to alternative systems.
- Fast delivery: KEMROC attachment was delivered and commissioned on-site within a week.
- Proven reliability and adaptability of the chain cutter attachment in challenging ground conditions.
The KEMROC EK 160 chain cutter is a dual-drum trench cutter equipped with a central cutting chain that eliminates the rock ridge typically left between conventional drum cutters. This unique design ensures a uniform trench profile, reducing the need for secondary finishing, hence boosting productivity, and reducing overall project’s cost.
Performance and Productivity
Once installed, the KEMROC EK 160 chain cutter demonstrated exceptional excavator trenching performance. The chain cutter trenching attachment achieved consistent production rates and a clean trench geometry, even in hard limestone. Operators noted smooth, low-vibration and low-sound operation, efficient cutting, and minimal pick wear thanks to the round attack pick configuration. Over multiple operational cycles, the KEMROC attachment consistently produced 16 linear meters of trench at 4.5 meters depth and 1 meter width: 72 m³ of rock excavated in just 90 minutes, highlighting the linear productivity KEMROC cutters are known for.
Advantages on Site
Using the KEMROC excavator trenching attachment provided several measurable benefits:
- Precision: Straight, smooth trench walls ideal for cable and pipeline installation.
- Efficiency: Faster progress with lower fuel consumption and reduced operator fatigue.
- Durability: Designed for sustained performance in abrasive materials.
- Cost-effectiveness: Minimized maintenance downtime and replacement costs.
Conclusion
This rock trenching project in Abu Dhabi reaffirmed why KEMROC remains a trusted brand for contractors aiming for maximum performance in excavation and trenching applications. The EK 160 excavator chain cutter combined power, precision, cost-efficiency and durability, proving once again that KEMROC’s trench cutter technology is the smart solution for modern construction projects.
With its chain cutter trenching attachment range, KEMROC continues to redefine excavator trenching, offering contractors a reliable path to cut smarter, work faster, and achieve more.
