Concrete cutter YG series

Overview
The hydraulic concrete wall saw is a rail-mounted cutting system engineered for precise, deep cuts in reinforced concrete walls. Configurations YG 600 and YG 700 separate the hydraulic power pack from the saw head to deliver continuous hydraulic torque while keeping the saw head compact and water-cooled for extended operation.

Main features

• Rail-mounted guidance for flat, accurate cuts and repeatable alignment
• Remote-control operation to keep personnel away from the rotating blade for improved onsite safety
• Separate hydraulic power pack and saw head design for stable high-pressure output and easier positioning
• Water-cooled saw head motor for sustained high-power operation with reduced head weight
• Multi-stage gearing and variable rotation speeds to match cutting conditions

Applications & Case Studies
Used for structural modifications, reinforcement works and creating openings (doors, windows, elevator shafts) in large buildings and infrastructure. Typical cases include deep penetrations in energy facilities and precision groove cutting for bridge reinforcement where rail-guided accuracy and continuous operation are required.

Core advantages

• High hydraulic efficiency and continuous stable torque suitable for deep cutting tasks
• Low vibration and minimal structural damage when operated with proper rail setup
• Robust components and separated power pack reduce downtime and total cost of ownership
