20inch/3500m3 China Cutter Dredger for River/Lake/Sea/Port Dredging Use

Weifang Jin Meng Dredger Co.,Ltd. located in Qingzhou, Weifang City, is a manufacturer for cutter suction dredger, work boat and gold dredging equipment,which is specialized in dredger researching, designing, production and sales.

We have professional R&D department, CAD drawing design center, quality control department and after-sales service department. Our company has more than over 500 employees, including 5 professional senior engineers on dredger building and researching, 16 designers on machinery construction, 8 engineers on quality inspecting and controlling as well as 10 after-sales service engineers.

Design__Cutter suction dredger design meets the requirements and regulations of CCS, BV and ABS , which are belonging to IACS.

The technology refer to Holland IHC, and dredger can be custom made according to customers' requirements.

Chief engineer Gan attended the “Local cutter dredger design study on IHC Beaver” in 2000.

Steel plate__ Raw material is marine use material which meets the requirements of CCS., and all plates are under sand blasting process.

Hydraulic system__Hydraulic oil pipes made by pipe bending machine to decrease the welding points so that can keep system stability. When the oil pipe finish, should be acid picking and  phosphating treatment to keep whole system clean and stability.

Dredging 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.

There are two ways for river cutter dredger being transported, if the sand dredger size smaller than JMD350, it is easy to transported by containers; if the river cutter dredger size is larger than JMD350, it will be transported by bulks. The river cutter dredger structure is dismuntable and assembled so that can be easy transported by trucks on road.

Cutter Dredgers

The cutter dredger we produce 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 cutter 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 dredger; at the end the slurry will be discharged by pipeline on land to the required place.

The design, construction, quality inspection is according to the standards and regulations of CCS. The steel plates are CCSB plates which meet the requirements of CCS.

The welders are skillful and experienced and certified under the regulations of CCS.

Anti-corrosion paints material are marine use under the requirements of CCS.

The installation concentricity of diesel engine is less than 0.05mm.

   -----The diesel engine brand is Cummins or DEUTZ, which technology is from America and Germany.

  ------The pump brand is Kingda which technology is from Australia Warman.

  ------The gearbox is China famous brand Hangzhou Qianjin Advance Gearbox.

  ------The hydraulic system brand is Rexroth which technology is from Germany,

  ------The PLC system is from Germany SIEMENZ.

  ------The bushes are from Japan NSK.

  ------The sealings brand is Parker from America.

Functions of cutter dredger: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads.

Working site of cutter dredger: sea, port, lake, and river.

Soil conditions: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.

 Installation

1) Party A will send 2 qualified and experienced engineers to Party B's workplace to direct and guide the cutter dredger's installation and training operating, if needed. .

2) To assist in the installation; Party B will arrange for 6-8 workers to aid these engineers.

3) Installation and test period is expected to take 10-15days for one cutter dredger with full ready of installation.

4) Party A's engineers must arrive at Party B's designated place within 3 days after the dredger has been transported to the workplace.

5) After the cutter dredger's complete installation, Party B Can coordinate Party A's engineers to test cutter dredger's performance in appropriate water. Dredger Test includes: operation of the dredging, hydraulic and electrical systems, running of the dredger's outfitting equipment, and Party A's engineers' debugging of the dredger's natural work.

The company is popular recognized by customers for strong technical strength, high quality dredgers and good after-sale service. At home the products are sold to dozens of domestic provinces, municipalities and autonomous regions; in abroad the dredgers are sold to India, Iran, Oman, the United Arab Emirates , Argentina, Colombia, Saudi Arabia, Bangladesh, Egypt, Nigeria, Mongolia, Russia and so on.

Innovation, custom made, delivery on time, and good quality will be the company concept with more and more customer cooperation and trust;

And it is also committed to dredger innovation and technology introduction of the United States and the Netherlands;

1). How is the river cutter dredger transported?

Answer:

There are two ways for river cutter dredger being transported, if the sand dredger size smaller than JMD350, it is easy to transported by containers; if the river cutter dredger size is larger than JMD350, it will be transported by bulks. The river cutter dredger structure is dismuntable and assembled so that can be easy transported by trucks on road.

2). What kind of service will supply after sales?

Answer:

After arrive cutter dredger arrive at clients' working site, we will send two experienced engineers for river cutter dredger body assembly and native workers' training. With the assist of ancillary equipment like excavators and cranes , the river cutter dredger assembly can be finished within 10days and training can be in one week.
