Product Description
The dredging floating crane is a high-performance, safe, and reliable dredging equipment that provides strong support for underwater excavation operations in rivers, oceans, lakes, and other water bodies. Equipped with heavy-duty grabs, it can effectively remove sand, silt, and gravel from the bottom, ensuring smooth navigation and waterway maintenance.
1. Main Functions and Uses of the Dredging Floating Crane
Dredging
Removes sediment in rivers, ports, lakes, and other waters to maintain waterway depth and prevent siltation.
Material Handling
Lifts excavated sand and waste to transport ships or shore treatment points.
Engineering Assistance
Participates in underwater foundation construction, ship salvage, and submarine pipeline laying.
2. Structural Characteristics of the Dredging Floating Crane
- Floating Platform: Based on barges or self-propelled floating bodies, it is suitable for water operations and has strong stability.
- Lifting System: Equipped with a high-power lifting mechanism, grab, or dredging device (such as a grab, shovel, or mud suction pipe).
- Rotating Mechanism: Most are designed to be fully rotating to expand the working range.
- Corrosion Resistance Design: Uses anti-corrosion coatings or corrosion-resistant materials to adapt to seawater environments.
3. Working Methods of the Dredging Floating Crane
Grab Type: Uses a heavy grab to collect underwater materials.
Suction Type: Combines with pump suction equipment to directly remove silt (must be equipped with a mud pump).
Mixing Type: Combines mining and lifting functions for high flexibility.
4. Application Scenarios of the Dredging Floating Crane
- Waterway Maintenance: Dredging of inland rivers or coastal waterways such as the Yangtze River and Pearl River.
- Port Construction: Expansion of wharves or harbor cleaning.
- Environmental Dredging: Controls polluted sediment and improves water quality.
- Emergency Rescue: Dredging of river channels after floods or typhoons.
5. Technical Advantages of the Dredging Floating Crane
Efficiency: Strong continuous operation capability with large processing capacity.
Flexibility: Not limited by shorelines; can be moved to different waters.
Adaptability: Equipped with GPS, sonar, and other positioning systems for precise operations.
Working Capacity: Lifting capacity can reach 350t, with a working radius of up to 28m.
Product Advantages: High strength and stability, capable of working in harsh environments. The dredging crane is also equipped with an advanced hydraulic and electrical system, enabling efficient digging and lifting operations.
