Concrete cutter YG series

Product overview
The hydraulic concrete wall saw is a rail‑mounted cutting system designed for precise, deep cuts in reinforced concrete walls. Configurations YG 600 and YG 700 separate the hydraulic power unit (power pack) from the saw head to deliver continuous hydraulic torque while keeping the saw head compact and water‑cooled for sustained operation. The system is intended for heavy‑duty structural modifications with minimal vibration and controlled cutting performance.

Main components

• Hydraulic power unit (hydraulic oil pump / power pack)
• Saw head with hydraulic motor (water‑cooled)
• Rail‑mounted guide system for precision and stable cuts
• Gearing and multi‑speed rotation for different cutting conditions

Core advantages

• Hydraulic power efficiency for continuous heavy‑duty cutting
• Deep cutting capability up to 730 mm (YG 700)
• Rail‑mounted guidance for straight, flat cuts and reduced structural vibration
• Remote operation capability to improve operator safety by distancing personnel from the rotating blade
• Water‑cooled saw head motor enabling higher sustained power with lower saw‑head weight for easier setup
• Separate power pack and saw head for improved portability and serviceability
• Robust components designed for continuous operation to reduce downtime and total cost of ownership

Q&A (selected)
Q: Why choose a hydraulic concrete wall saw over other types?
A: Hydraulic wall saws are suitable for heavy‑duty projects that require sustained torque and continuous cutting. The hydraulic drive provides consistent torque and component reliability for thick concrete walls.

Q: How is the precision of the wall saw machine guaranteed?
A: Precision is achieved via the rail‑mounted guide system; rails provide stable guidance so large‑area cuts remain flat and accurate, helping to protect structural integrity.

Q: How to choose between a diamond wire saw and a wall saw?
A: Use a diamond wire saw when cutting depths exceed ~730 mm or when the workpiece is irregular. For flat walls up to 730 mm, a hydraulic wall saw generally offers better speed and precision balance.

Applications and case studies
The hydraulic concrete wall saw is used for structural modification, reinforcement and opening formation (doors, windows, elevator shafts) in large buildings and infrastructure. Typical projects include deep penetration openings at energy facilities and precision groove cutting for bridge reinforcement where rail‑mounted accuracy and continuous operation are required.
