4. FAQ for Sand mining dredger
1). Sand mining dredger test before-ex-factory
Do your sand mining dredger have a test before ex-factory?
Answer: Yes, it must be. Each sand mining dredger must be tested very well before ex-factory so that can guarantee sand miningdredger 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 and the sand mining dredger will be transported to the port for loading. |
2). Sand mining dredger transportation
How is the sand mining dredger transported?
Answer: There are two ways for sand mining dredger being transported, if the sand mining dredger size smaller than JMD350, it is easy to transported by containers; if the sand mining dredger size is larger than JMD350, it will be transported by bulks. The sand mining dredger structure is dismountable and assembled so that can be easy transported by trucks on road. |
3). Sand mining dredger after sales service
What kind of service will supply after sales?
Answer: After sand mining dredger arrive at clients' working site, we will send two experienced enginneers for sand mining dredger body assembly and native workers' training.
