Depth 20m Cutter Suction Dredger

Weifang Jin Meng Depth 20m Cutter Suction Dredger

Our company depth 20m cutter suction dredger is self-propelled or non self-propelled，portable cutter suction dredger. The hull uses dismantle and box-like structure, Its dismantle type can be assembly at working place easily and be transported by road, railway and container accordingly, convenient in installation and working place moving from one to another. The power system can be designed to electric system or diesel engine driving system according to customers’ requirements.Equipment on the depth 20m cutter suction dredger are as bellows: traversing device, cutter ladder lifting device, spuds and deck crane. 

The working process is as following: the cutter head cut the sand and mud underwater to mixture of slurry, then through dredging pump to the pipeline on depth 20m cutter suction dredger; at the end the slurry will be discharged by pipeline on land to the required place.

Weifang Jin Meng Depth 20m Cutter Suction Dredger Details

Design

Our depth 20m cutter suction dredger is designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee they are well-designed and practical.

Cummins Engine

The depth 20m cutter suction dredger is equipped with world famous powerful Cummins engine, which are famous for its durability, lower oil consumption, standardized accessories and easy maintenance.

Hydraulic system

The most important parts of depth 20m cutter suction dredger and wheel bucket dredger. The hydraulic system requirements are very high and strict; it’s the main artery of the entire dredger. Lateral traction winches, lifting winch and cutter head of the dredgers are driven by hydraulic motors.An integral hydraulic system includes hydraulic oil tanks, hydraulic pump, hydraulic valve manifold, solenoid valve, hydraulic pipes, hydraulic components, electrical actuator and so on.

Detachable Structure

The depth 20m cutter suction dredger is detachable, so it is easy to transport when delivering or moving from one working site to another.

Shijiazhuang Pump

Flow passage components use High wear resistant alloy Cr27 to prolonged the pump service life, pump shaft seal use packing seal which is easy to maintain , and anti-friction bearings are from Japanese brand NSK.

Cutter head

For one cutter head, there are 5 blade, 8 teeth equipped on one blade. There is material High chromium. for easy-wearing proof.Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.

Weifang Jin Meng Depth 20m Cutter Suction Dredger Other Can be Cumstomized

The depth 20m cutter suction dredger 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 low bridge and transportation 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.
