Concrete rebar hydraulic cutter YG-CF series

high-strength

Overview
An excavator-mounted hydraulic rock saw uses high-speed diamond blades to cut rock and reinforced concrete with low vibration. Compared with hydraulic breakers, the vibration‑controlled design enables clean, continuous cuts, reduces secondary trimming and grinding, and increases cutting output for quarrying, road demolition, trenching and deep foundation excavation.

Key benefits

• Clean, continuous diamond-blade cutting with minimal vibration and noise.
• Protects adjacent foundations and structures, lowering secondary finishing costs.
• Deep cutting capability up to 1,400 mm for thick concrete and large rock blocks.
• Model range scalable to excavator classes from mini (2 T) to heavy (30 T).

Technical parameters (model table)

• YG-CF1 — Suitable excavator: 2–4 T; Saw disc diameter: 0.4–0.8 m; Cutting width: 5 mm; Max cutting depth: ≤400 mm; Pressure: 30 MPa; Flow: 30 L/min; Field application: mini excavators, indoor demolition, shallow trenching.
• YG-CF2 — Suitable excavator: 6–9 T; Saw disc diameter: 1.2–1.6 m; Cutting width: 9 mm; Max cutting depth: ≤800 mm; Pressure: 30 MPa; Flow: 80 L/min; Field application: road repair, utility trenches, light limestone.
• YG-CF3 — Suitable excavator: 10–18 T; Saw disc diameter: 1.8–2.2 m; Cutting width: 14 mm; Max cutting depth: ≤1100 mm; Pressure: 30 MPa; Flow: 120 L/min; Field application: medium utility trenches, granite slitting, concrete.
• YG-CF4 — Suitable excavator: 20–30 T; Saw disc diameter: 2.0–2.8 m; Cutting width: 20 mm; Max cutting depth: ≤1400 mm; Pressure: 30 MPa; Flow: 190 L/min; Field application: quarry stone blocks, heavy rock, deep foundation pits.

Selection guidance

• Match excavator operating weight, saw disc diameter, cutting width and maximum cutting depth to the model specifications.
• For frequent vertical and horizontal cuts, prefer a mounting hitch with 360° rotation or 90° tilt to reduce repositioning time.
• Use hydraulic motors with protective control valves when machine flow/pressure varies to protect drive seals and maintain blade speed.

Applications

• Quarries and dimension stone mining: cut straight boundary seams on blocks to reduce blasting fracturing and improve stone recovery.
• Urban road demolition and concrete slitting: cut clean trenches through reinforced concrete up to 1,400 mm thick without disturbing adjoining roadbeds.
• Utility trenching and deep foundation excavation: produce clean vertical edges for safe excavation and foundation work.
• Attachment workflow on complex sites: after precise boundary cuts by the rock saw, crews commonly switch to hydraulic breakers, drum cutters, screening buckets, concrete pulverizers and augers as required.

Case summary
In one quarry application, matching a heavy YG-CF4 rock saw (2.8 m disc, 1,400 mm max depth, 30 MPa, 190 L/min) to a 20-ton excavator increased dimension stone yield by ~80%, produced clean block edges without secondary grinding and reduced operating costs significantly.

Operator tips

• Let blade weight and steady hydraulic feed do the cutting; avoid forcing the boom to prevent blade jamming.
• Maintain steady hydraulic feed speed and continuous water cooling to reduce diamond-segment wear and prevent heat damage.
• Clean rock dust from inside the blade guard daily to avoid hardened deposits that can lock the drive shaft.

Frequently asked points

• Single vs double blade: Single blades reach deeper cuts (up to 1,400 mm). Double blades cut two parallel seams simultaneously for block cutting and edge profiling.
• Hydraulic mismatch effects: Insufficient flow reduces blade speed and cutting effectiveness; low pressure can stall motors. Use matched flow/pressure or protective control valves.
