Cutter Dredger

The dredger we produce is self-propelled or non self-propelled,portable cutter 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 cutter dredger; at the end the slurry will be discharged by pipeline on land to the required place.

FAQ for River cutter dredger

1). Do your river cutter dredger have a test before ex-factory?

Answer:

Yes, it must be. Each river cutter dredger machinery must be tested very well before ex-factory so that can guarantee river cutter dredger performance at customers' working sites and save the time and cost for customers. Before test we will send invitation letters to the clients to invite them come and do the performance inspection by themselves, after get the clients permission and the river cutter dredger will be transported to the port for loading.

2). 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.

3). 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.
