Excavation dredge machine description

The excavation dredge machine 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 excavation dredge machine 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.

Design

Our excavation dredge machine are designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee their dredging work performance and practical well.

Functions of excavation dredge machine: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads.

Working site of excavation dredge machine: sea, port, lake, and river.

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

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;

The excavation dredge machine can be custom made according to customers’ requirements:

1. Anchor booms installation

2. Spud carriage

3. Dredger position of 5 anchors.

4. Hydraulic driving for spud flat down(to pass and transport on water safely).

5. Make the dredger with extra dredging pump underwater to deepen dredging depth for 20-30m underwater and slurry concentration is more than 30%.

6. Make the dredger with booster station to further the discharge distance.
