KEMROC KTR 65 Trencher Attachment for Cable Trenching Project.
John Deere 135G | Cutting Sandstone in West Virgina, USA.
Project Overview & Challenges
When a leading excavation contractor in West Virginia needed a reliable solution for precise trench excavation in sandstone, the KEMROC KTR 65 proved why modern trenching technology is replacing conventional methods in utility and infrastructure projects across the United States.
Mounted on a John Deere 135G excavator, the KEMROC KTR 65 was deployed for a trenching application involving sandstone excavation with a compressive strength of 40 MPa (5,802 psi). The project required an accurate 8-inch-wide cable trench with a trench depth of 36 inches, demanding both precision and high production efficiency in challenging rock conditions.
KEMROC Built for Precision Trenching in Rock
Unlike traditional trenching machine solutions or oversized chain trencher systems, the KTR 65 was specifically selected for its ability to deliver narrow trenching with minimal over-excavation. For this West Virginia contractor, maintaining a controlled trench profile was critical for utility trenching and cable installation applications.
One of the key reasons the contractor chose KEMROC over other trench cutter and hydraulic chain cutter solutions was the innovative auto-cleaning feature of the KTR range. This technology continuously clears excavated material from the cutting area, helping maintain consistent productivity even during trenching in rock and cutting sandstone formations.
The result is cleaner trench walls, improved trench accuracy, and a more efficient excavation workflow.
Exceptional Pick Consumption and Lower Operating Costs
In hard rock trenching applications, tool wear is often one of the biggest operational concerns. However, the KEMROC KTR 65 delivered exceptional performance with less than one round attack pick consumed per 100 cubic meters excavated so far.
This extremely low wear rate highlights the efficiency of the KEMROC KTR cutting system in sandstone excavation applications while significantly reducing downtime and maintenance costs for the trenching contractor. Compared to conventional rock trenching methods such as breakers or oversized chain trencher systems, the KTR solution provides:
- Lower tooling consumption
- Lower vibration
- Reduced overbreak
- Cleaner trench excavation
- More accurate trench depth control
Smart Trenching Technology for Modern Infrastructure
As utility installation and infrastructure development continue to expand across the United States, contractors are increasingly searching for smarter trenching solutions capable of handling trenching in rock efficiently and economically.
The KEMROC KTR 65 demonstrates how advanced trenching technology can transform difficult sandstone excavation into a precise and productive operation. Whether for cable trench projects, utility trenching, or narrow rock trenching applications, the KTR range delivers the accuracy, durability, and performance modern excavation contractor’s demand.
Less over-excavation. Less downtime. More trenching performance.
