Bucket Ladder Dredger
Dredging Vessels
Ideal for the extraction of sand and gravel with an endless chain of buckets
- Dredging depth: up to 25 meters
The Bucket Ladder Dredger, also known as the bucket chain dredger, is a highly efficient tool for sand extraction. It operates by using a power unit to drive a reducer, which rotates the corner wheel, moving the chain. The buckets on the chain then scoop up sediment from the waterbed, and the material is processed through a screening system to separate sand and gravel.
With a dredging depth ranging from 4 to 40 meters below the water’s surface, this dredger can simultaneously excavate and screen sand and medium-sized stones on board. The materials can be transported directly to shore via a remote pump through pipelines or loaded onto transport vessels for further delivery to distant docks.

- Strong Excavation Capability: The dredger can efficiently extract larger materials such as gravel and pebbles, and it also performs well in harder soil conditions. It is suitable for various underwater environments, excluding rock formations.
- High Extraction Efficiency: With a higher bucket capacity, the dredger can operate continuously, allowing it to excavate and transport more sand and gravel per unit of time compared to other types of dredgers.
- Energy-Efficient and Effective: Combining both extraction and screening processes into one step, this dredger improves overall operational efficiency while reducing energy consumption.
