Royang River Sand Suction Dredger
A river sand suction dredger is a self-propelled or non-self-propelled portable river sand dredging machine. Its hull adopts a detachable box-type structure. The detachable design allows easy on-site assembly and convenient transportation by road, railway or container, making installation and relocation between work sites hassle-free. The power system can be configured as an electric system or a diesel engine drive system according to customer requirements.
The river sand suction dredger is equipped with the following equipment: traversing device, cutter ladder lifting device, spuds and deck crane. Its working process is as follows: the cutter head cuts underwater sand and mud to form a slurry mixture, which is then pumped through the dredging pump to the pipeline on the river sand suction dredger; finally, the slurry is discharged to the designated location on land via the pipeline.

Royang River Sand Suction Dredger Details
Design
Our river sand suction dredger is designed by senior engineers with years of professional experience in dredger construction and dredging operations, ensuring a well-engineered and practical design.
Cummins Engine
The river sand suction dredger is equipped with the world-renowned high-performance Cummins engine, known for its durability, low fuel consumption, standardized accessories and easy maintenance.
Hydraulic system
The hydraulic system is one of the most critical components of both river sand suction dredgers and wheel bucket dredgers. It has extremely high and strict performance requirements, serving as the core power system of the entire dredger. The dredger’s lateral traction winches, lifting winch and cutter head are all driven by hydraulic motors.
A complete hydraulic system includes hydraulic oil tanks, hydraulic pumps, hydraulic valve manifolds, solenoid valves, hydraulic pipes, hydraulic components, electric actuators and other parts.
Detachable Structure
The river sand suction dredger features a detachable design, enabling easy transportation during delivery or relocation between different work sites.
Shijiazhuang Pump
The flow passage components are made of high-wear-resistant Cr27 alloy to extend the pump’s service life. The pump shaft uses packing seals for easy maintenance, and the anti-friction bearings are sourced from the Japanese brand NSK.
Cutter head
Each cutter head is fitted with 5 blades, and each blade has 8 teeth. It is made of high-chromium material for excellent wear resistance.
The cutter head is driven by a hydraulic motor, and the cutter bearing is equipped with a lubrication and sealing unit.
FAQ for Royang River Sand Suction Dredger
Do your river sand suction dredger have a test before ex-factory?
Answer: Yes, every river sand suction dredger must undergo thorough testing before leaving the factory. This ensures stable performance at the customer’s work site and saves customers time and costs. Before testing, we will send an invitation to customers to inspect the equipment’s performance in person. Only after obtaining the customer’s approval will the river sand suction dredger be transported to the port for shipment.
How is the river sand suction dredger transported?
Answer: There are two main transportation methods for the river sand suction dredger. Models smaller than RYD350 can be easily shipped in containers, while models larger than RYD350 are transported by bulk carriers. Thanks to its detachable and modular structure, the dredger can also be easily transported by road trucks.
What kind of service will supply after sales?
Answer: After the river sand suction dredger arrives at the customer’s work site, we will dispatch two experienced engineers to oversee on-site assembly and train local workers. With the assistance of auxiliary equipment such as excavators and cranes, assembly can be completed within 10 days, and the training program lasts one week.
