Product Description

8 Inch River Cutter Suction Dredging Machine with Siemens PLC Control 
 

Feature	Description
Construction	The cutter suction dredger is manufactured with a steel structure, available in both non-self-propelled and self-propelled dismountable types. It can dock and dredge in any coastal areas and inland rivers.
Application	Suitable for excavating and transporting cohesive sediments of grade III and below as specified in the dredging construction technical specifications issued by the Ministry of Water Resources of the People's Republic of China.
Hull Structure	The dredger hull consists of a main pontoon and two side pontoons, which can be easily disassembled or assembled for transport by road, rail, or water, and reassembled at the project site.
Engine and Dredge Pump Placement	The engine and dredge pump are located in the central pontoon, while the two side pontoons serve as fuel tanks, ballast tanks, and storage rooms.
Power Source	Powered by diesel engines; the main diesel engine drives the dredge pump, and auxiliary engines drive the hydraulic system, including the cutter, swing and ladder winches, anchor winches, and spud cylinders.
Control Room	The spacious control room is ergonomically designed, providing a 360-degree panoramic view. All operation buttons, switches, indicators, and gauges are installed on the control console. A single operator can control the entire dredger from the control room.
Anti-Corrosion Coating	The dredger is coated with four layers of marine paint to prevent corrosion. Zinc anodes can be used to provide enhanced anti-corrosion protection.

 

 

 

•Cutter Head: The cutter head is one of the most core working parts of the cutter suction dredger. 

1. Loosening & Cutting: Breaks up compacted soil, sand, or rock, enabling efficient suction.

2. Feeding Material: Directs loosened sediment toward the suction pipe for removal.

3. Material-Specific Design:

   • Stone Cutter Head: Heavy-duty, equipped with robust teeth for hard rock or gravel.

   • Sand Cutter Head: Lighter, optimized for soft sediments like sand or clay.

•Portal Frame: The gantry of a cutter suction dredger plays a critical role in supporting the dredging operation

1. Structural Support:Supports/lowers the cutter head and absorbs operational forces (cutting, currents).

2. Pipeline Management:Suspends and stabilizes the slurry discharge piping during dredging.

3. Operational Platform: Provides access for maintenance and equipment control.

 

•Crane: A slewing crane fixed on the deck for loading and unloading cargo. 

1.Cargo Handling:Performs loading/unloading of materials on deck with a rotating turntable and adjustable boom.

2.Multi-Axis Mobility:Simultaneously operates lifting, luffing (boom angle adjustment), and slewing (rotation) for flexible positioning.

3.Integrated Design:Combines boom, hoist, luffing/slewing mechanisms, and control room on a single turntable, pivoting around a fixed pillar for stability.

 

 

•Anchor Boom: Move the traverse anchor forward to meet the requirements of traverse excavation of the reamer.

1. Positioning & Stability:Secures the dredger in place by deploying anchors, preventing drift during operations.

2. Swing Control:Controls the vessel's lateral movement (swing) for systematic dredging coverage.

3. Force Absorption:Handles tension from anchor cables and environmental forces (currents/waves) to maintain operational stability.

 

 

•Operating Cabin: The control system integrates advanced technologies like frequency conversion and electronics to optimize dredging efficiency.

1. Automated Control: Utilizes electronic systems for precise operation of dredging equipment.

2. Energy Efficiency: Employs frequency conversion technology to reduce power consumption.

3. Customized Operation: Adapts to different working conditions with selectable modes for optimal performance.

•Spud: Special pencil piles for positioning and shifting dredgers.

1. Positioning Stability: Provides firm anchoring to maintain the dredger's position during operation.

2. Controlled Shifting: Enables controlled forward movement (stepping) for systematic dredging progress.

 

Product Quality Control

The dredgers will use the best parts from world-renowned brands, including Cumins engines, Shijiazhuang pumps, Hangzhou gearboxes, and Siemens PLC control systems.

The hydraulic system is one of the most crucial components of cutter suction dredgers. The cutter head, ladder winch, swing winches, and spud or spud carriage are driven by hydraulic motors, ensuring higher efficiency and durability. Reputed brands are also used for other hydraulic parts, such as hydraulic pipes, pumps, and valves.
