2.Simple Description: 
A stationary dredger, fixed on anchors and moved while dredging along semi-arcs by winches. It has an endless chain of buckets, that fill while scraping over the bottom. The buckets are turned upside down and empty moving over the tumbler at the top. The dredger material is loaded in barges.  

They comprise a rectangular pontoon with a central well in which a heavy steel frame or ladder is suspended. The ladder supports an endless chain of buckets, each of which is equipped with a cutting edge. By rotating the bucket chain about flat-sided wheels (known as tumblers) at each end of the ladder, material can be loosened and transported. This type can also be self-propelled. The propulsion machinery is used to move the vessel from site to site, but is not used in the dredging operation.  

Combined with other device, bucket dredger can be used as gold/iron extraction machinery, and sand washing, sieving machinery.
