Dredgers, as professional underwater dredging equipment, boast their core feature of flexible operational capabilities. Equipped with various working devices such as chain buckets, drag buckets, or grabs, they can cater to the cleaning needs of various substrates like silt, sand, and gravel. The automated control system achieves excavation and concentration adjustment, significantly enhancing construction efficiency. The modular design balances draft depth and operational radius, meeting the requirements of different water bodies such as coastal and inland rivers. The environmentally friendly mud discharge system effectively controls turbidity diffusion, while also offering stability against wind and waves and reliability for continuous long-term operations. It is a key piece of equipment for waterway maintenance and port expansion projects.
