In a desert region of Qatar, a civil engineering contractor was struggling with a critical infrastructure project. The job required cutting trenches through dense Simsima limestone—a rock formation known across the Gulf for its toughness. The contractor had been using hydraulic hammers to break the rock, but the process was slow, noisy, and produced uneven results. The project was falling behind schedule, and the client was applying pressure.
The contractor needed a more precise and efficient method for rock cutting. After researching alternatives, he discovered an excavator rock saw from YG Machinery—specifically the YGJ10 model with 360° rotation. This rock saw attachment for excavators features an 1800mm saw blade, delivers 3100Nm of torque, and is designed for 30-40 ton excavators.
The difference was immediate. The Qatari crew now cuts through the limestone with clean, straight lines at speeds up to 10 meters per hour. The rock saw produces minimal vibration, reduces noise significantly compared to hammers, and eliminates the need for secondary breakage. The contractor completed the trenching work ahead of the revised deadline and has since ordered a second unit for another project.

Technical Parameters Of The Excavator Rock Saw
Below are the specifications for the YGJ series rock saw attachments. The Qatari contractor chose the YGJ10 with 360° rotation.

Why the YGJ10 with 360° rotation suited the Qatari project:
- 1800mm saw blade – deep enough to cut through the limestone trenches required for the drainage infrastructure.
- 3100Nm torque – powerful enough to handle the dense Simsima limestone without bogging down.
- 360° rotation – allowed the operator to cut from any angle, essential for trench corners and complex geometries.
- 700kg weight – well‑matched to the 35‑ton excavator, keeping the machine balanced and stable.
Three Challenges That Made Rock Cutting Difficult In Qatar
The Qatari contractor faced three problems common across the region’s construction sector.
Problem 1: Hard, Abrasive Limestone
The Simsima limestone formation in Qatar is dense and tough, often slowing progress and increasing costs. Hydraulic hammers bounce off the surface or cause excessive fracturing, requiring multiple passes and extensive cleanup.
Problem 2: Noise And Vibration Restrictions
Many infrastructure projects in Qatar are located near residential areas or existing structures. Hydraulic hammers generate high noise levels and ground vibration, leading to complaints and potential damage to nearby buildings.
Problem 3: Imprecise Cutting
Hammers produce irregular break lines. The contractor then needed additional equipment to trim and shape the trenches. This added labor, time, and material waste.
The excavator rock saw solved all three.
How The Rock Saw Attachment For Excavator Transformed The Qatari Project？
The YGJ series rock saw is a hydraulic‑driven circular saw that mounts directly on the excavator arm. The diamond‑tipped blade spins at high speed, cutting through rock with a grinding action rather than impact. The result is a clean, straight cut with minimal waste.
Precision Cutting
The Qatari contractor now cuts trenches to exact specifications. The 1800mm blade produces a straight, vertical wall that requires no additional trimming. The 360° rotation allows the operator to adjust the cutting angle without repositioning the excavator.
Reduced Noise And Vibration
Because the rock saw attachment for excavator uses a rotating blade rather than impact force, noise levels are significantly lower than those of a hydraulic hammer. Ground vibration is minimal. The contractor received no complaints from nearby residents.
Higher Productivity
The rock saw for excavator cuts through limestone at speeds up to 10 meters per hour, depending on the rock hardness. This is substantially faster than hammering, which often requires multiple passes. The contractor completed the trenching work in half the time originally estimated.
Versatile Applications
Beyond trenching, the unit handles:
- Roadside cutting for utility installation
- Quarry stone cutting for building materials
- Concrete demolition for structural removal
- Foundation excavation in rocky ground
Real Feedback From The Qatari Infrastructure Contractor
After three months of using the YGJ10 rock saw for excavator, the project manager shared his results.
- Cutting speed: 8‑10 meters per hour through Simsima limestone, compared to 2‑3 meters per hour with a hammer.
- Noise levels: Reduced by approximately 60% compared to the hydraulic hammer.
- Vibration: Minimal. No complaints from nearby structures or residents.
- Finish quality: Clean, straight cuts. No secondary trimming required.
- Labor: Reduced the crew from four workers to two.
- Payback: The rock saw attachment for the excavator paid for itself within three months through time savings alone.
The project manager said, “We were losing money on every meter of trench. The hammer was too slow, too noisy, and the finish was terrible. The excavator rock saw changed everything. It cuts through the limestone like a knife through butter. The 360° rotation means we can cut corners without repositioning. I am ordering another unit for our 40‑ton excavator.”
An operator added: “The rock saw for excavator is easy to control. I set the speed, lower the blade, and follow the line. The blade lasts longer than I expected—we have cut over 500 meters, and it is still going strong. The machine is much quieter than the hammer. My ears thank me every day.”
