High-Performance, Low-Cost Dredger Ship Widely Used In Rivers, Lakes, Oceans, And Reservoirs
1. Why Choose Leader Dredger Hydraulic Dredger Ship?
Leader Dredger Co., who integrates design & research, production, export and after-sale service, is a professional high quality Chinese manufacturer for cutter suction dredgers with many branch offices in Asia, Mid-East, Africa countries etc, one of the largest annual sale for cutter suction dredgers.
Leader dredger, on the march to a world famous brand name, is your ideal choice for dredging machinery!
All our products will be tested in the testing center before leaving the factory, and will be dismantled and shipped to the port. During the test, all tests are the same as the dredger at the work site, and the operational performance and product safety will be tested and recorded. This test will reduce the debugging time on the job site and
increase the training time for workers.
1. Strong adaptability. Cutter suction dredgers can be widely used in rivers, lakes, oceans, reservoirs, etc. for sand and mud dredging, waterway cleaning and reclamation.
2. High efficiency. The cutter suction dredger can dred and discharge sand at the same time, without other ships. Therefore, the cost will be greatly reduced, and they can reach a large production capacity of several thousand cubic meters per hour and a discharge distance of several kilometers.
3. Easy to operate. With the hydraulic system and PLC control system, all dredger operations can be completed in the operating room.
4. Quick disassembly and assembly.
5. Customized design can be made according to customer's project requirements. Our engineers have many years of experience in ship design.
6. The dredger will use the best parts, such as the world-famous Cummins engine, Shijiazhuang pump, Hangzhou gearbox, Siemens PLC control system.
7. The hydraulic system is one of the most important parts of a cutter suction dredger. The cutter head, trapezoidal winch, rotary winch, pile or pile frame are driven by hydraulic motors to improve efficiency and durability. Hydraulic pipes, hydraulic pumps, hydraulic valves and other hydraulic parts are all of well-known brands.
8. The dredger is detachable. Therefore, they can be easily disassembled and assembled. Therefore, it is convenient for road, rail or water transportation.
9. Professional engineers will be sent to the project site to request the customer to carry out the installation, commissioning, testing and operator training of the dredger.
2 . About 18 Inch Dredger Ship Application
1. The sand dredger for sale is used for cleaning river silt, sand production and mining projuct.
2. Suitable for heavy duty opetations in tripical climates and in sheltered waters.
3. Applied to dredging rivers, lakes and ponds, reclaiming land, cleaning ports and pumping sand.

3. Dredger Ship Feature
About 18 Inch Dredger Ship Cutter Head
For one cutter head, there are 5 blade,6 or 7 teeth equipped on one blade. There is material Cr. for easy-wearing proof. Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.
The cutter motor is hydraulic driven low speed and high torque heavy duty design. The cutter motor is mounted on the cutter front piece on the ladder end. A special cover is provided to protect the motor from damage due to sand, rocks and debris. The cover can be removed from easy inspection and maintenance.
About 18 Inch Dredger Ship Hydraulic winch
To support the ladder, a hoisting winch is provided at the front of the main pontoon, which is installed on a solid foundation. The winch is hydraulically driven by the reduction gear box in the winch structure. The winch has a disc brake, which is automatically activated when the pressure drops. The winch is operated from the control room
and has a fixed speed.
For the lateral pull of the ladder, there are two winches at the front of the main pontoon, which are installed on a solid foundation. The winch is hydraulically driven by the reduction gear box in the winch structure. The winch has a disc brake, which is automatically activated when the pressure drops. The winch is operated from the control
room with variable speed.
About 18 Inch Dredger Ship Hydraulic system
The hydraulic system is the most important part of the river sand dredger and bucket wheel dredger. The hydraulic system is very demanding and strict; it is the main artery of the entire sand dredger. The side traction winch of the dredger, the lifting winch and the cutting head are driven by hydraulic motors.
We use hydraulic pressure to drive the entire dredger, including winches, cutting machines, hydraulic cylinders, etc. The valve is REXROTH, and the hydraulic control system is SIEMENS PLC.
