Hydraulic dredger YG series

remote-controlled

Product Overview
A dredging robot designed for efficient removal of silt and sludge from rivers, lakes, reservoirs and ponds. Remote-controlled and shore-powered via a hydraulic station, the YG series replaces manual dredging and conventional small dredgers for contractors and municipal water authorities.

How it Works
The unit operates submerged and is piloted remotely from shore. A shore-based hydraulic power unit connects to the robot via high-pressure hoses. The robot advances on tracked drives, uses a suction pump to collect sediment and transmits real-time video and positioning data for precise dredging. Suited to deep, narrow or difficult-to-access locations.

Main Features and Benefits

• High efficiency: Continuous operation with extended daily working periods.
• Operator safety: Crew remain on land, eliminating exposure to unstable banks and contaminated sludge.
• Energy efficiency: Lower fuel and energy use compared with many traditional dredgers.
• Precision cleaning: Effective in narrow channels, ponds and treatment tanks while minimizing environmental disturbance.
• Smart control: Real-time video and positioning enable accurate trenching and spot cleaning.

Main Application Areas

• Port channel and berthing maintenance for navigation and draught recovery.
• Inland river and canal management to restore flow and habitat quality.
• Lake and reservoir dredging to recover storage capacity and limit eutrophication.
• Industrial and municipal wastewater treatment facilities for sediment and sludge removal.
• Water conservancy projects: underwater excavation, pipeline clearing and maintenance.
• Emergency response and post-disaster cleanup in challenging conditions.
