River Dredging Machine Boat with Cutter Head for Port Construction

River dredging machine description

The dredger we produce is self-propelled or non self-propelled,portable cutter suction dredger. The hull uses dismantle and box-like structure, which 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. Generally, it has functions on dredging, conveying and discharging of mud or sand. It can produce certain amount of vacuum by the centrifugal pump.

The dredge 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 sets supplies electricity for lighting and emergency use when it doesn’t working.

The dredger is moved by alternate swing of the spuds. The spuds are lifted by the hydraulic cylinder.

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

The hydraulic oil pump is driven by the auxiliary diesel engine.

Functions of cutter suction dredger: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads.

We can produce dredgers according to the requirements of the customers.

Functions of river dredging machine

dredging river, dredging sand, desilting, reclamation for channels and land, and building roads.

We can produce dredgers according to the requirements of the customers.

Applicability this machine:

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

Construction: it consists of three pontoons: one main pontoon and two side pontoons. The pontoons are connected by the connecting pieces and tightened by high intensity bolts and nuts.

Working site of cutter suction dredger: sea, port, lake, and river.

Soil conditions: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.

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.

Design

Our cutter suction dredgers are designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee their dredging work performance and practical well.

Skilled workers & ex-work testing

Every cutter suction dredger is built by skilled workers and inspected strictly to assure the high quality and durability. Each finished dredger will be tested in our testing center to make sure it work smoothly before delivered to customers.

Dismountable Structure

The river dredging machine are detachable, so it is easy to be transported on road by trucks when working site is changed to another place.

Assembly & Staff Training

Our experienced engineers will arrive at the working site within one week to guide, teach and train customer’s native workers to debug and operate the dredger until they can operate skillfully by themselves.

The dredgers can be custom made according to customers'requirements:

1. Anchor booms installation

2. Spud carriage

3. Dredger position of 5 anchors.

4. Hydraulic driving for spud flat down(to pass and transport on water safely).

5. Make the dredger with extra dredging pump underwater to deepen dredging depth for 20-30m underwater and slurry concentration is more than 30%.

6. Make the dredger with booster station to further the discharge distance.
