Weifang Jin Meng Dredger Co.,Ltd. located in Qingzhou, Weifang City, is a manufacturer for river dredger machine, work boat and gold dredging equipment,which is specialized in river dredger machine 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 river mining machine building and researching, 16 designers on river mining machine construction, 8 engineers on river ming machine quality inspecting and controlling as well as 10 after sales service engineers.

The river dredger machine we produce is self-propelled or non self-propelled,portable river mining machine. 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 river mining machine are as bellow: traversing device, cutter ladder lifting device, spuds and deck crane. The river mining machine 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 river mining machine; at the end the slurry will be discharged by pipeline on land to the required place.
