This is a very convenient small dredging equipment. The pump is directly fixed by the winch and the winch is controlled to change the depth of the pump underwater, so it can be dug very deep.

Because Portable dredger is not equipped with reamer equipment, it is more suitable for relatively soft riverbeds.
