Product & applications
About the rock saw
A single-blade hydraulic rock saw for cutting rock and reinforced concrete. Select the blade for the material and match the drive to the excavator hydraulic supply.
Features & benefits
Reversible rotation
The drive operates in both directions, including reversal when freeing a blade from a cut.
Hydraulic blade brake
Automatic braking stops the blade when power to the saw is removed.
Rotatable guard and support
The guard and stand allow the blade position to be adjusted for left- or right-side access.
Protected motor bearings
A supported hub, double bearings and dust sealing protect the motor connection.
Typical applications
- Quarry rock cuttingCut suitable granite, basalt, marble and other stone using the corresponding blade.
- Reinforced-concrete cuttingCut suitable reinforced-concrete sections during demolition and removal.
- Roadworks and trenchingMake controlled cuts for road removal, excavation and trench preparation.

Installation requirements
Confirm the attachment fits your excavator
Before ordering, send the machine identification and the connection, power and working information relevant to this product.
- D1 / D2
- Both pin diameters
- C
- Pin centre distance
- W
- Clear mounting width
Excavator and load
Check the specified 20–45 t excavator range, saw weight, lifting radius and working clearance.
Hydraulic supply
Compare recommended flow and operating settings with maximum limits; confirm return, brake and control requirements.
Mounting and blade clearance
Verify the bracket and actual pin geometry, blade diameter and space for guard movement.
Material and cooling
Provide material type, cut dimensions, reinforcement and available cooling water. Select a blade explicitly rated for that material.
Product questions
Rock saw questions
Can one blade cut every material?
No. Diamond and other tipped blades have different intended materials. Use the blade specification for the actual rock, concrete or metal.
What excavator weight range does this model specify?
The individual model table lists a 20–45 t excavator range. Also check the complete attachment weight, lifting radius, mounting connection and available hydraulics.
Is maximum flow the recommended flow?
No. This model table distinguishes recommended flow from maximum flow. Confirm operating settings before installation.
Can I choose using excavator weight alone?
No. Also confirm the actual mounting connection, attachment weight and excavator lifting capacity. Powered tools need the specified hydraulic supply.
Which information is needed for a quotation?
Send the excavator model, mounting dimensions, work requirements, quantity and delivery destination.
