Dredging, conveying and discharging of mud and sand.

Desilting, reclamation for channels and land, and building roads.

Relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.

To pass low bridge easily, the controlling room and rest room are dismountable. Connecting parts for cabin room and deck are easily dismounted joints.

 It consists of three pontoons: 1 main pontoon and 2 side pontoons. The pontoons are connected by the connecting pieces and tightened by high intensity bolts and nuts.

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.

Specifications of HL 500 dredger

There are 3 pontoons in dredger, which including 1 main pontoon and 2 side pontoons. And also pontoons are dismantle type can be different parts in order to transported convenient by truck, then installation at working site.

Because pontoons of dredger are designed wider and longer, they are transported in bulk vessel from the sea. And also in the transportation process, pontoons are anti-corrosion paint, then it doesn't matter which place they will be put, in the deck or at the bottom of the vessel.
