China suction sand cutter dredger hydraulic system operation

 YHWNC 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, fashion layout and strong power. The maximum dredging depth can reach 25 m and discharge distance 3000 m .

The technical options of the dredgers are customized and truly flexible

--totally up to the customer's requirement and the working environment.

1. Design

    Our sand dredging machine are designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee they are well-designed and practical.

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. Hydraulic system

     Hydraulic system: the most important parts of 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.

5. Detachable Structure

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

6. 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.

7. cutter head

Our cutters are exposed to continuous technical development and provide an ideal solution for every cutter dredging challenge. They can be fitted with a variety of teeth and replaceable cutting edges to offer the full spectrum of standard and customised excavation tools for all types of bottom soil.

The cutterhead is integrated within vessels to deliver high productivity and minimal downtime thanks to the profile, spacing and size of the arms, as well as the location, orientation and form of the teeth. An example is the newly developed Lancelot cutterhead. In loose compacted soil, it makes better use of the available power, resulting in a higher output of dredged material thanks to its cylindrical shape and availability of more arms.
