Royang River Sand Dredging Cutter Suction Dredger
The river sand dredging cutter suction dredgers we produce are available in both self-propelled and non-self-propelled models, featuring a portable design suitable for river sand dredging operations. The hull adopts a detachable box-like structure, which enables 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 installed on the river sand dredging 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 pumped through the dredging pump to the pipeline on the river sand dredging cutter suction dredger; finally, the slurry is discharged to the required on-land location through the on-board pipeline.

Royang river sand dredging cutter suction dredger Feature and Application
This Royang river sand dredging cutter suction dredger is equipped with horizontal shifting devices, cutter ladder lifting devices, spud devices, deck crane and other supporting equipment. It can also be fitted with anchoring poles and trolley devices based on actual operational requirements. In general, the river sand dredging cutter suction dredger integrates the functions of dredging, conveying and discharging mud or sand. It can generate a certain level of vacuum through a centrifugal pump, ensuring efficient suction and transportation of river sand slurry.
Royang River Sand Dredging Cutter Suction Dredger Details
Design
Our river sand dredging cutter suction dredgers are designed by senior engineers with years of professional experience in shipbuilding and dredging projects. This professional design team ensures that each river sand dredging cutter suction dredger is scientifically structured, practical in use and fully adaptable to on-site river sand dredging conditions.
Cummins Engine
Each river sand dredging cutter suction dredger is equipped with the world-famous and high-performance Cummins engine. This engine is widely recognized for its strong durability, low fuel consumption, standardized spare parts and simple maintenance, providing stable and reliable power support for the long-term continuous operation of the river sand dredging cutter suction dredger.
Hydraulic system
The hydraulic system is one of the most critical components of both the river sand dredging cutter suction dredger and the wheel bucket dredger, with extremely strict performance requirements—it serves as the core "artery" that ensures the normal operation of the entire dredger. The lateral traction winches, lifting winch and cutter head of the dredgers are all driven by hydraulic motors, which guarantees stable, efficient and smooth operation.
A complete hydraulic system is composed of hydraulic oil tanks, hydraulic pumps, hydraulic valve manifolds, solenoid valves, hydraulic pipelines, hydraulic components, electrical actuators and other essential parts, all working together to ensure the stable and efficient operation of the entire hydraulic system.
Detachable Structure
The river sand dredging cutter suction dredger adopts a detachable structure, which greatly simplifies transportation during delivery or when moving the equipment from one working site to another. This design effectively reduces transportation costs and improves overall work efficiency, especially for long-distance transportation.
Shijiazhuang Pump
The flow passage components of the pump are made of high-wear-resistant Cr27 alloy, which significantly extends the service life of the pump, even when handling abrasive river sand. The pump shaft seal uses 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 sand dredging cutter suction dredger is equipped with 5 blades, and 8 teeth are installed on each blade. The cutter head is made of high-chromium material, which has excellent wear resistance and can withstand the abrasive nature of river sand during dredging operations.
The cutter head of the river sand dredging cutter suction dredger is driven by a hydraulic motor, and the cutter bearing is equipped with a lubrication and sealing unit. This unit effectively prevents sediment and river water from entering the bearing, ensuring the long-term stable operation of the cutter head.

Pipes and Floaters
The river sand dredging cutter suction dredger is equipped with dedicated pipelines for solid material (river sand) discharging. These pipelines usually consist of three parts: pipes, floaters and rubber hoses, which are specially designed to adapt to river dredging working conditions.
There are three types of pipes available for customers to choose from according to the type of solid material (river sand) to be discharged: steel pipes, HDPE pipes and self-floating pipes, each with unique advantages to meet diverse operational needs.
Customers have the option to purchase pipes either independently or from our company. If customers have special requirements for the pipelines, we can provide customized pipeline solutions according to their specific needs.
Regarding shipping packaging: the pipelines will be shipped in 40" HQ containers to ensure safe transportation and avoid damage during long-distance shipping.
Kind reminder: customers are advised to purchase additional pipelines as spares to avoid operational delays caused by pipeline damage or wear during river sand dredging operations.
