Dredging ships are suitable for conditions with abundant sand resources or a high stone content, primarily used for sand mining operations in sandpits, rivers, reservoirs, ports, coastal areas, and more.
Sand dredging vessels are suitable for narrower waterways and are divided into cutter suction and jet suction dredgers. Both types of dredgers can be selected based on different geographical conditions such as the sediment content of riverbed sand, the content of river pebbles, and the speed of flowing sand. Sand dredging vessels are more adaptable to complex geographical environments than sand挖掘 vessels.

A sand dredger consists of a hull, a large frame, buckets, chains, a transmission system, a reduction system, a power system, a separation system, and more.

The sand pump ship is a pump-type, consisting of the hull, power, sand pump, rubber hose, etc. The lower suction depth is 5-35 meters.
