What size excavator do I need for a hydraulic rock saw attachment?

Question

VANROCK Group · Accepted Answer

The right excavator size depends on three main factors: the saw’s hydraulic flow and pressure requirement, the attachment weight, and the cutting depth and material you need to handle. In general, smaller rock saws suit compact and mid-size excavators for utility trenches and lighter profiling work, while larger units need heavier excavators with stronger auxiliary hydraulics and enough operating weight to keep the machine stable during cutting. Carrier setup matters as much as machine tonnage, including one-way or two-way auxiliary circuits, case drain requirements, coupler configuration, and arm geometry. Cutting hard, abrasive rock usually demands more torque and a larger, more capable host machine than cutting softer limestone or asphalt-over-rock conditions. VANROCK manufactures and supplies rock saw attachments for excavators and can help you confirm compatibility from your excavator’s hydraulic specs, carrier weight, and required cut depth before providing a quote.
