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.

A dredger is an engineering vessel mainly used for dredging, channel dredging, land reclamation, sand extraction and other construction projects in rivers, lakes, seas and other water bodies. Dredgers can be divided into rake suction dredgers, cutter suction dredgers, chain bucket dredgers, grab bucket dredgers, etc. according to their working principles.

Dredgers can be classified into various types based on their working principles and uses. Among them, the rake suction dredger sucks in sediment through the suction pipe and transports it to the mud tank on the ship; The cutter suction dredger uses a cutter device to cut the sediment and transport it to a designated location through a mud pump and pipeline; The grab dredger, on the other hand, uses a large grab to directly grab sediment, making it suitable for excavating harder soil. In addition, there are various types of dredgers such as chain bucket and bucket to meet the needs of different projects.

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.
