The brief introduction to bucket dredgers

Common dredger types in the United States and abroad include cutter suction type, bucket wheel type, chain bucket type, bucket type, grab type, and so on. Bucket dredgers are primarily used to remove silt, silt, gravel, gravel, boulders, and other materials from the seafloor, but they can also be used for channel dredging, wharf construction, and seabed engineering excavation. Grab dredgers are classified into two types: self-propelled and non-self-propelled. The self-propelled type typically has a mud tank, and once full, it will self-propel to the mud discharge area for unloading; the non-self-propelled type loads and unloads mud using mud barges.

The grab dredger digs and grabs the sediment by inserting the mud layer and closing the grab and then manipulating the ship when dredging. The special crane mechanically raises the grab from the water, rotates to a predetermined position, and unloads the sand into the mud cabin or mud barge, and so on.
