Sand dredging vessels are suitable for conditions with abundant sand resources or a high stone content, primarily used for sand mining operations in sandpits, rivers, reservoirs, docks, coastal areas, and more.
Sand dredging vessels are suitable for narrower waterways and are divided into cutter suction and jet suction types. Both types of sand dredging vessels can be chosen based on different geological conditions such as silt content in riverbed sand, cobble content, and the speed of flowing sand. Sand dredging vessels are better suited to complex geological environments compared to sand mining vessels.

The sand dredger is a chain bucket type, consisting of the hull, large frame, bucket, chain, transmission system, reduction system, power system, separation system, etc.

The sand pump boat is composed of a hull, power source, sand pump, and flexible hoses, etc. The dredging depth ranges from 5 to 35 meters.
