A Crawler Dredging Robot is a heavy-duty, track-mounted machine engineered to clear hardened sediment, gravel, and sludge from confined underwater environments. Manual dredging in sewers and settling tanks exposes workers to toxic gases (like H2S) and structural collapse. Traditional vacuum trucks often fail when the sludge is too dense or contains heavy aggregate.
Our machines solve this by combining high-torque hydraulic track drives with high-chrome alloy pump impellers. Six standard models handle pipe diameters from 500mm to large open culverts. They generate pump flows from 100m³/h to 250m³/h and pass solids up to 50mm without clogging. YG Machinery manufactures every unit in our Zhengzhou facility. We bypass dealers, offering factory-direct pricing that saves you 15-20%. Every unit undergoes a 4-hour continuous load test before shipping.

How to Read These Specs for Your Project:
- Particle Pass Size: If your lines contain heavy gravel or construction debris, the YG700 and above (40 mm- 50 mm pass size) are mandatory to prevent impeller jams.
- Pump Head: The YG1200 can push slurry vertically 30 meters and horizontally up to 150 meters. This allows the hydraulic station to remain at surface level while the robot works deep in the line.
- Motor Power: For long-duration municipal work, the 18kW and 22kW electric motors provide stable, zero-emission power. For remote mining pits without grid access, the YG1200 offers a reliable 123kW diesel configuration.

How Does an Underwater Cleaning Machine Work?
An Underwater Cleaning Machine operates on a hydraulic agitation and suction cycle. It is not just a vacuum; it uses high-pressure water jets to break down compacted sediment before extraction.
Here is the engineering process:
- Descent and Positioning: The operator lowers the unit using the 0-10 r/min winch. Underwater LED lights allow the operator to visually align the suction head with the blockage.
- Hydraulic Agitation: High-pressure hydraulic water jets blast the hardened sludge, converting it into a pumpable slurry.
- High-Torque Extraction: The main pump creates a strong vacuum. The impeller is designed to pass solid particles up to 50mm, preventing the machine from stalling on rocks or debris.
- Continuous Discharge: The slurry travels up the discharge hose. The hydraulic system (running at 0-16 MPa) ensures consistent torque, even when pumping thick, heavy mud.
The entire process is monitored via the wireless remote. The operator can adjust the travel speed (3-15 m/s) and pump engagement instantly based on the density of the material.
Why Choose a Remote Control Dredging Robot for Safety?
A Remote Control Dredging Robot eliminates the need for Confined Space Entry (CSE). This directly protects your crew and reduces your liability.
- Zero Human Exposure: Sewer gas (H2S, methane) is lethal. By keeping operators above ground, you bypass the need for expensive gas monitors, ventilation blowers, and rescue teams.
- Collision Resistance: The tracked chassis is built with heavy-duty steel. It handles pipe joints and minor collapses without getting stuck.
- Instant Emergency Stops: The wireless remote features an E-stop. If the pump jams or the camera feed is lost, the operator can halt all movement instantly.
- Continuous Duty Cycle: Unlike human workers, the unit does not fatigue. It operates 24/7 in high heat or freezing conditions, keeping your project on schedule.

Where Does an Underwater Cleaning Machine Work Best?
An Underwater Cleaning Machine eliminates the need for manual entry across multiple demanding industries. Here is how our models adapt to specific site challenges:
- Municipal Sewers & Storm Drains. The YG500 and YG600 easily navigate 500- 600 mm pipelines. They remove compacted sand, grit, and grease that standard vacuum trucks cannot break apart, restoring flow capacity without street excavations.
- Industrial Settling Ponds. Chemical plants and steel mills use the YG800 and YG900 to clear thick, abrasive sludge. The high-chrome impeller handles chemical precipitates without clogging, allowing for continuous operation during scheduled plant maintenance.
- River Silt Removal. The YG1200’s high-capacity 250m³/h pump and 150m horizontal discharge distance make it ideal for dredging riverbeds and canals. It clears silt from a single setup point on the bank without needing floating barges.
- Mining Tailings & Sumps. The YG1200 diesel model operates entirely off-grid. It pumps heavy mineral tailings and abrasive slurries up to 50mm in particle size from deep sumps, ensuring processing plants never back up.
- Power Plant Intakes. Cooling water screens accumulate mussels and sediment. The compact YG700 clears these structures underwater, preventing costly plant shutdowns while keeping divers out of hazardous intake currents.
- Agricultural & Septic Tanks. The compact YG500 fits through standard 600mm tank hatches. It agitates and pumps out hardened sludge in minutes, making it a highly efficient tool for commercial septic service fleets.
Each model can be equipped with an optional live-feed camera, allowing operators to target specific blockages in zero-visibility conditions
