A:
 

Working principle: First the hydraulic cutter in the ladder dredges clay below water, then dredged sand moved by the rotated

cutter mixes with water and form liquid medium.Then the sand liquid in the inner cutter blade and beside the marine pump

suction functioned by the fluid power of sand pump, enters sand pump, meanwhile, get some energy,at last, it is discharged

 to the destination through discharge pipe

B:

 1.     Simple, rapid assembly and dismantling

2.     Spare parts and floating pipe available

3.     Transportable by road, rail or sea

4.     Reliable hydraulic system

5.     Fresh water engine cooling system

6.     Efficient fuel consumption

7.     Simple operation.(the most advanced PLC control system)

C:

All the products are with different sizes for customers choices

We have professional R&D departmen, CAD drawing design center, quality control department and after-sales service department. Our company has more than over **0 employees, including 5 professional senior engineers on dredger building and researching, *6 designers on machinery construction, 8 engineers on quality inspecting and controlling as well as *0 after-sales service engineers. The annual turnover has been more than billions of RMB. To go ahead, we have cooperated with port offices, channel dredging departments and riverway administrations. To meet the needs of market and the customers, We also have signed primary agency agreements with trade companies in more than ten countries such as Brazil, Argentina, Benin, Egypt, Poland, Nigeria, Ukraine, Indonesia, and North Korea. During recent years, the cutter suction dredgers, gold panning dredgers and assorted ore selecting platforms on sea we produced have been successfully exported to above countries.
