Multifunctional Amphibious Dredger for Shallow Water Areas with Et500 Model

Product Description

Product Description

Watermaster / Amphibious Dredger

Watermaster Amphibious Dredger is a versatile machine designed for dredging, excavation, aquatic weed removal, and waterway maintenance. With its unique amphibious design, it can travel and operate efficiently on land, in shallow water, wetlands, marshes, and soft terrain where conventional dredgers cannot reach.

The machine supports multiple attachments, including a cutter head, suction pump, excavator bucket, rake, piling hammer, and aquatic weed cutter, allowing one machine to perform various tasks. Its hydraulic propulsion system and intelligent controls provide excellent mobility, precise operation, and high working efficiency.

Widely used for river dredging, lake restoration, reservoir maintenance, channel cleaning, environmental projects, industrial sedimentation ponds, and wetland management, the Watermaster significantly reduces equipment investment, labor costs, and project duration while delivering an environmentally friendly dredging solution.

DREDGER ATTACHMENTS

Dredger Attachment

1. Cutter Head (Cutter Head Assembly)
The cutter head is designed for high-efficiency breaking and loosening of compacted materials such as hard soil, clay, gravel, and rock layers. Equipped with wear-resistant teeth, it ensures stable cutting performance under heavy-duty dredging conditions.
Its optimized structure delivers strong digging force while maintaining smooth hydraulic operation, making it ideal for challenging dredging environments.

 
2. Rake Attachment
The rake is used for cleaning, vegetation removal, and loose sediment collection. It efficiently gathers debris, aquatic plants, and soft materials without disturbing the surrounding structure.
With a reinforced frame and high-strength rake teeth, it offers excellent durability and low resistance during operation, making it suitable for river and lake maintenance projects.

 
3. Digging Bucket
The digging bucket is a versatile excavation attachment designed for sand, gravel, silt, and general earthwork. Its large-capacity structure improves loading efficiency and reduces working cycles.
Built with reinforced wear-resistant steel, the bucket delivers stable penetration performance and long service life, even in abrasive working conditions.

 
4. Discharge Pipe System
The discharge pipe system is responsible for long-distance slurry transportation with high efficiency and stability. It ensures smooth material flow from the dredging site to the discharge area.
Made with high-strength, wear-resistant materials, it provides excellent sealing, reduced blockage risk, and easy connection for modular dredging operations.

 
5. Quick Change System (Optional Function)
The quick change system allows operators to switch between different attachments rapidly and safely, significantly improving operational efficiency.
Its hydraulic locking structure ensures firm connection and stable performance, reducing downtime and increasing overall productivity in multi-task dredging projects.

 
6. Hydraulic Power Interface System
The hydraulic interface system provides stable power transmission to all attachments, ensuring consistent performance under varying working conditions.
It is designed for easy maintenance, high reliability, and compatibility with multiple Watermaster working tools, supporting continuous heavy-duty operation.
