RYD550D Depth 20m Cutter Suction Dredger

The Depth 20m cutter suction dredgers manufactured by our company come in two types: self-propelled and non-self-propelled, both with a portable design. The hull adopts a detachable box-type structure, which allows for easy assembly at the work site and convenient transportation by road, railway or container. This design not only simplifies the installation process but also makes it easy to move the equipment from one work site to another. According to customers’ actual needs, the power system can be designed as either an electric system or a diesel engine-driven system. The equipment equipped on the Depth 20m cutter suction dredger includes the following: traversing device, cutter ladder lifting device, spuds and deck crane. Its working process is as follows: the cutter head cuts and crushes underwater sand and mud into a slurry mixture, which is then delivered to the pipeline on the Depth 20m cutter suction dredger through the dredging pump; finally, the slurry is discharged to the required location on land via the on-board pipeline.

Soil conditions: The Depth 20m cutter suction dredger can adapt to a variety of soil types, including relatively hard soil, compacted sand, sludge, sea sand, river sand, clay, mud and so on.

Royang Depth 20m Cutter Suction Dredger Details

Design

Our Depth 20m cutter suction dredgers are designed by senior engineers who have rich professional experience in shipbuilding and dredging projects. This ensures that each Depth 20m cutter suction dredger is scientifically designed, practical and can fully meet the needs of on-site operations.

Cummins Engine

The Depth 20m cutter suction dredger is equipped with the world-famous and high-performance Cummins engine. This engine is well-known for its strong durability, low oil consumption, standardized accessories and easy maintenance, which can provide stable and reliable power support for the long-term continuous operation of the Depth 20m cutter suction dredger.

Hydraulic system

The hydraulic system is one of the most important components of both the depth 20m cutter suction dredger and the wheel bucket dredger, with very high and strict requirements—it is the core part 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 ensures 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 components, which work together to ensure the smooth operation of the entire hydraulic system.

Detachable Structure

The depth 20m cutter suction dredger adopts a detachable structure, which makes it very 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 can effectively extend the service life of the pump. The pump shaft seal adopts a packing seal, which is easy to maintain, and the anti-friction bearings are from the famous Japanese brand NSK, ensuring the stable operation of the pump.

Cutter head

Each cutter head of the depth 20m 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 adapt to harsh working environments.

The cutter head of the depth 20m cutter suction dredger is driven by a hydraulic motor, and the cutter bearing is equipped with a lubrication and sealing unit, which can prevent sediment from entering and ensure the long-term stable operation of the cutter head.

Royang Depth 20m Cutter Suction Dredger Other Can be Cumstomized

The depth 20m cutter suction dredger can be customized according to customers’ specific requirements, and the available customization options are as follows:

1. Installation of anchor booms to improve the positioning stability of the depth 20m cutter suction dredger during operation.

2. Configuration of spud carriage to realize more flexible and accurate positioning of the dredger.

3. Installation of 5 anchors to ensure the accurate positioning of the depth 20m cutter suction dredger in complex working environments.

4. Hydraulic drive for spud lowering, which enables the depth 20m cutter suction dredger to safely pass under low bridges and ensures safe transportation on water.

5. Adding an extra underwater dredging pump to the depth 20m cutter suction dredger, which can increase the dredging depth to 20-30 meters underwater and make the slurry concentration more than 30%.

6. Equipping the depth 20m cutter suction dredger with a booster station to extend the discharge distance of the slurry.
