Overall length: 23.3m

Main engine model: WD615.C-28 125kw
Advantage: Compared with a non-self-propelled dredger, self-propelled dredger does not need to rely on an external power drive, and the dredger with sailing power itself is suitable for construction in the waterway where larger ships pass, and the grab dredger is mainly used for dredging clay, silt, hatching stone, and it is suitable for grabbing fine sand and powder sand. It can be used for dredging waterways and river silt so that other ships can pass smoothly, and it can also be used for sand
Operation process: The bucket dredger uses the boom and steel cable of the rotary dredger to hang the bucket; under the action of the weight of the bucket itself, it is put into the seabed to grab the mud. Then the bucket winch is turned on and the bucket rope is passed through the pulley at the top of the boom to close the grab and lift it up, and then the dredger is turned to a predetermined point (or mud barge) to unload the mud. The dredger turns back to the excavation site for dredging, and so on.
