Types Of Dredgers - Jet Suction Dredger - Leader Dredger

Similar to the cutter suction dredger, the jet suction dredger does not have a cutter head, it is equipped with a high-pressure water gun, and the suction pipe is pushed vertically into the sand sediment. The water spray helps to blow up the sand for easy inhalation.
The mixture is loaded into the barge or sent directly to the filling area through pipelines.

Because there is no cutter head, jet suction dredger can only be suitable for relatively soft riverbed. The structure is much simpler than the cutter suction dredger, and the cost is much lower.
