The dredger we produce is self-propelled or non self-propelled,Portable cutter suction river sand 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 suction 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 space is enough and easy for maintain.

1) Party A will send 2 qualified and experienced engineers to Party B's workplace to direct and guide the 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 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 dredger's complete installation, Party B Can coordinate Party A's engineers to test 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.
