Mounting a heavy excavator rock saw boosts hard rock cutting output by more than two times compared to standard tools. Traditional breakers often create strong vibrations, high noise, and stress cracks in high-hardness granite or limestone, which can damage nearby foundation structures.
A hydraulic rock saw uses high-speed diamond blades to make clean, continuous cuts in rock and concrete. This vibration-free design protects surrounding buildings and cuts secondary trimming costs significantly.
How Do You Select an Excavator Rock Saw by Weight and Cutting Depth?
Selecting an excavator rock saw requires matching excavator weight, saw disc diameter (M), cutting width (mm), maximum cutting depth (mm), working pressure (Mpa), and oil flow (L/min). Check the official technical parameters below:
| Model | Suitable Excavator | Saw Disc Diameter | Cutting Width | Max Cutting Depth | Pressure | Flow | Field Application |
| YG-CF1 | 2 ~ 4T | 0.4 ~ 0.8M | 5mm | ≤400mm | 30Mpa | 30L/min | Mini excavators, indoor demolition, shallow trenching |
| YG-CF2 | 6 ~ 9T | 1.2 ~ 1.6M | 9mm | ≤800mm | 30Mpa | 80L/min | Road repair, utility trenches, light limestone |
| YG-CF3 | 10 ~ 18T | 1.8 ~ 2.2M | 14mm | ≤1100mm | 30Mpa | 120L/min | Medium utility trenches, granite slitting, concrete |
| YG-CF4 | 20 ~ 30T | 2 ~ 2.8M | 20mm | ≤1400mm | 30Mpa | 190L/min | Quarry stone blocks, heavy rock, deep foundation pits |
Operator Tip: If you cut both vertical and horizontal seams often, choose a mounting hitch with 360-degree rotation or 90-degree tilt to save repositioning time.
Where Do Contractors Deploy an Excavator Rock Saw on Jobsites?
- Quarries and Granite/Limestone Mining: An excavator rock saw cuts straight boundary seams on dimension stone blocks, reducing interior cracks from blasting and increasing stone recovery rates.
- Urban Road Demolition and Concrete Slitting: Operators cut clean trenches through reinforced concrete roads up to 1400mm thick without disturbing adjoining road beds.
- Utility Trenching and Deep Foundation Excavation: Cutting vertical edges along foundation trenches ensures clean side walls and safe excavation.
- Jobsite Attachment Teamwork: On complex mining and demolition sites, after the rock saw makes precise boundary cuts, crews can switch to a hydraulic breaker to knock out the cut rock slabs quickly. Operators can also use a drum cutter for fine wall profiling, mount a screening bucket to sort rock fragments, run a hydraulic concrete pulverizer for secondary rebar separation, and attach an excavator auger to drill foundation holes.
Operator Tip: Never force the boom down hard while cutting. Let the blade weight and steady hydraulic pressure do the work to prevent blade jamming.
How Did an Excavator Rock Saw Help an Australian Quarry?
- Jobsite Challenge: Quarry manager Mark in Queensland, Australia faced low stone yield when blasting granite blocks. Traditional blasting fractured stone internally, causing a 40% waste rate and drawing noise complaints from local residents.
- Equipment Solution: YG Machinery matched a heavy excavator rock saw with water-cooling jets (Model: YG-CF4, 2.8m saw disc diameter, 1400mm max cutting depth, 30Mpa pressure, 190L/min flow) to his 20-ton excavator.
- Real Business Results: Dimension stone yield jumped by 80%, producing clean block edges without secondary grinding. Blasting complaints fell to zero, cutting quarry operating costs by over $22,000 per month.
Operator Tip: Wash out rock dust inside the blade guard every evening. Caked rock dust hardens overnight and locks up the drive shaft.
Frequently Asked Questions About Excavator Rock Saw Selection
Single blades achieve deeper cuts (up to 1400mm) for thick concrete slab removal and deep trenching. Double blades cut two parallel seams at once, speeding up quarry block cutting and utility edge profiling.
Maintain steady hydraulic feed speed and ensure continuous water cooling flow. Water removes abrasive slurry instantly while keeping diamond segments cool to prevent heat damage.
Low oil flow (below required 30-190L/min) slows blade speed and prevents effective cutting. Low oil pressure causes hydraulic motors to stall in 30Mpa rock. Choose hydraulic motors with control valves to protect drive seals.
