The most important parts of cutter suction dredger and wheel bucket dredger. The hydraulic system requirements are very high and strict; it’s the main artery of the entire sand dredger. Lateral traction winches, lifting winch and cutter head of the sand dredger are driven by hydraulic motors.

Cummins engine

Testing equipped on the discharge pipeline on the sand dredger. The sand dredger has Cummins engine and hydraulic system for easily operation.

Yes, it must be. Each dredging equipment must be tested very well before ex-factory so that can guarantee 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 inspectation by themselves, after get the clients permition adn the Sand dredger will be transported to the port for loading.

Answer:

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

Answer:

Aftersand dredger arrive at clients' working site, we will send two experienced enginneers for cutter dredger body assembly and native workers' training.
