The dredger we produced is self-propelled or non self-propelled, portable cutter suction dredger. The hull uses dismantle and box-like structure, assembly at working site, which is equipped with horizontal shifting devices, cutter ladder lifting devices, spud devices, deck crane and so on. It can also be equipped with anchoring poles and trolley devices to increase capacity.

The dredger pump is driven by the main diesel engine through the reducing gear box.

The alternator, which driven by the auxiliary diesel engine, supplies electricity for power and lighting of the whole dredger.

Generator supplies electricity for lighting and emergency using when dredger doesn't work.

The shifting winches, cutter ladder and lifting winch are driven by the hydraulic motor.

The design, construction, quality inspection is according to the standards and regulations of CCS. The hull, machinery equipments and other spares are at the requirements of CCS. The hull is square, cross keel, which is full welding steel structure, and authorized by CCS.
