The JLWNC 10/8, 12/10, 14/12, 16/14, 20/18, 22/20 series dredgers can

apply to all kinds of soils, which are widely used in port, waterway dredging

and reclamation works. This series of dredgers, absorbing advanced technology

of Dutch and American related products,have advantages of totally hydraulic

control system, simple operation, easy maintenance, rational design, novel

layout and strong power. The maximum dredging depth can reach 25m and

discharge distance 3000m.

Working environment:

1.The range of adaptation to the environment: the temperature no higher than 40 degrees Celsius in summer and winter temperatures not lower than -10 degrees Celsius, the air humidity is no more than 30%, wind power does not exceed 7 in rivers.

2. River ore requirements: sand ratio is no less than 60% (clay content is no more than 10% scree content is no more than 15% gravel content is no more than 15% Wind Stone is no higher than 10%.)

3. The ship diesel engine should apply to the CIS countries grade use of fuel, oil.

4. The ship is equipped with night-time lighting system suitable for all weather conditions and working uninterrupted.

5 .2-3 person operate every time.

6.The entire dredger is equipped with safety barriers.

Why choose us?

1. Design

We have built good relationship with many famous domestic ship-design institutes.Thedredgers are designed by senior engineer, who have specialized in dredging machine building and hydraullic system with many years.

2. 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 works smoothly when delivering to customers.

3. Cummins Engine

The dredgers are equipped with world famous powerful Cummins engine, which are famous for its durability, lower oil consumption, standardized accessories and easy maintenance.

4. Pump(Shijiazhuang Pump)

Australia Warman Tecnology, best pump in China

5. Hydraulic system

Hydraulic system: the most important parts of cutter suction 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.

6.Detachable Structure

The cutter suction dredgers are detachable, so it is easy to transport when delivering or moving from one working site to another.

7. Assembly & Staff Training

Our experienced installers will arrive at the construction site to guide, teach and training your staff to debug and operate the dredger until they can operate skillfully by themselves.

Now we have 4 sets of dredger in stock, expecting to your visit!
