Product Description

Weifang Hairui Xinsheng Environmental Protection Equipment Manufacturing Co., Ltd., located in Qingzhou city---one of the Nine Ancient Cities in China, is leading company of China mining equipment. We specialize in producing various types of cutter suction dredgers,Customize various products according to customer requirements.
Can widely to meet the many dreding working situation such as: inland waterway dredging\port construction\river dredging\lake silt and clay dredging\land reclamation\salt lake so on.

•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.

Application

Application Scenarios of Dredging Vessels

1.River Dredging:  Maintains navigational depth by removing silt and sediment buildup.

2.Port Construction: Excavates harbor basins and approach channels for vessel access.

3.Channel Dredging:Ensures safe passage for commercial ships by deepening shipping lanes.

4.Lake Cleaning:Removes eutrophic sludge to improve water quality.

5.Underwater Tunneling:Prepares trenching paths for subsea pipelines or cable laying
