Weifang Jin Meng Dredger Co.,Ltd. located in Qingzhou, Weifang City, is a manufacturer for sand mining dredger, work boat and gold dredging equipment,which is specialized in dredgeing equipment researching, designing, production and sales.

We have professional R&D department, CAD drawing design center, quality control department and after sales service department. Our company has more than over 500 employees, including 5 professional senior engineers on sand miningdredger building and researching, 16 designers on machinery construction, 8 engineers on quality inspecting and controlling as well as 10 after sales service engineers.

Cutter head

For one cutter head, there are 6 blade,7 teeth equipped on one blade. There is material Cr. for easy-wearing proof.

Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.

Hydraulic system:

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

 JICHAI engine

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

KINDA Pump

Flow passage components use High wear resistant alloy Cr27 to prolonged the pump service life, pump shaft seal use packing seal which is easy to maintain , and antifriction bearings are from Janpanese brand NSK.

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.

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.

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. With the asist of ancillary equipment like excavators and cranes , the sand mining dredger assembly can be finished within 10days and training can be in one week.
