RYD550 River Desilting Cutter Suction Dredger

Royang River Desilting Cutter Suction Dredger

The river desilting cutter suction dredgers we produce are available in both self-propelled and non-self-propelled models, featuring a portable design tailored for river desilting tasks. The hull adopts a detachable box-type structure, enabling easy on-site assembly and flexible transportation via road, railway or container. This design not only simplifies the installation process but also makes it convenient to relocate the equipment between different work sites. According to customers’ specific operational needs, the power system can be designed as either an electric system or a diesel engine-driven system. The key equipment fitted on the river desilting cutter suction dredger includes: traversing device, cutter ladder lifting device, spuds and deck crane. Its working process is as follows: the cutter head cuts underwater sand and mud into a slurry mixture, which is then delivered to the pipeline on the river desilting cutter suction dredger through the dredging pump; finally, the slurry is discharged to the required on-land location via the on-board pipeline.

Royang River Desilting Cutter Suction Dredger Details

Design

Our river desilting cutter suction dredgers are designed by senior engineers with years of professional experience in shipbuilding and dredging projects. This ensures that each river desilting cutter suction dredger is scientifically designed, practical in use, and fully meets the demands of on-site desilting operations.

Cummins Engine

The river desilting cutter suction dredger is equipped with the world-famous and high-performance Cummins engine. This engine is widely praised for its strong durability, low fuel consumption, standardized accessories, and easy maintenance, providing stable and reliable power support for the long-term continuous operation of the river desilting cutter suction dredger.

Hydraulic system

The hydraulic system is one of the most critical components of both the river desilting cutter suction dredger and the wheel bucket dredger, with extremely strict performance requirements—it acts as the main artery that ensures the entire dredger operates normally. The lateral traction winches, lifting winch, and cutter head of the dredgers are all driven by hydraulic motors, guaranteeing stable and efficient operation.

A complete hydraulic system includes hydraulic oil tanks, hydraulic pumps, hydraulic valve manifolds, solenoid valves, hydraulic pipes, hydraulic components, electrical actuators, and other essential parts, all working together to ensure the smooth and stable operation of the entire system.

Detachable Structure

The river desilting cutter suction dredger features a detachable structure, which makes it convenient to transport during delivery or when moving from one working site to another, effectively reducing transportation costs and improving work efficiency.

Shijiazhuang Pump

The flow passage components of the pump are made of high-wear-resistant Cr27 alloy, which effectively extends the service life of the pump. The pump shaft seal adopts a packing seal design for easy maintenance, and the anti-friction bearings are sourced from the well-known Japanese brand NSK, ensuring the pump’s stable performance and long service life.

Cutter head

Each cutter head of the river desilting cutter suction dredger is equipped with 5 blades, and 8 teeth are installed on each blade. High-chromium material is used to make the cutter head, which provides excellent wear resistance to cope with harsh underwater working environments.

The cutter head of the river desilting cutter suction dredger is driven by a hydraulic motor, and the cutter bearing is equipped with a lubrication and sealing unit, which prevents sediment from entering and ensures the long-term stable operation of the cutter head.

Royang river desilting cutter suction dredger After Sales Installation

1) If required, Party A will send two qualified and experienced engineers to Party B's workplace to guide the installation of the river desilting cutter suction dredger and train Party B's staff on its operation.

2) To assist with the installation, Party B shall arrange 6-8 workers to support these engineers.

For one river desilting cutter suction dredger with all installation preparations completed, the installation and testing period is expected to take 10-15 days.

3) Party A's engineers must arrive at the location designated by Party B within 3 days after the river desilting cutter suction dredger is transported to the workplace.

4) After the complete installation of the river desilting cutter suction dredger, Party B may coordinate with Party A's engineers to test the dredger's performance in suitable water areas. The dredger test includes: operation of the dredging, hydraulic and electrical systems, operation of the dredger's outfitting equipment, and debugging by Party A's engineers to ensure the dredger works normally.
