The chain bucket dredger uses a dredging bucket mounted on two parallel steel cables to excavate sediment, and uses a chain wheel and steel cable at the top of the bucket tower to pull the dredging bucket for excavation and unloading. This type of ship is suitable for excavating harder soil. The grab dredger uses a large grab to directly grab sediment, suitable for excavating harder soil or salvaging underwater objects.

In the vast ocean and vast rivers and lakes, there is an unknown yet crucial role - the dredger. It is not only a powerful assistant in water construction, but also a key force in river dredging, port expansion and other projects. This article will take you in depth to understand the working principle, types, and applications of dredgers in modern engineering.
