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

The main products of our company are sand suction dredger ,dredger machinery, mineral processing dredger machinery, sand washing dredger machines, sand pumping dredgers, auto-load and auto-unload sand transporting dredgers, iron extraction dredger machinery (water election, dry election), gold mining dredgers, high standard sand washing dredger machinery, sand making dredger machinery, transportation dredger, stone crushing dredger machinery, large and medium-sized dredging ships.

The sand suction dredger we produce is self-propelled or non self-propelled,portable sand suction 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 dredger are as belows: 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 small sand dredger; at the end the slurry will be discharged by pipeline on land to the required place.

Functions of sand suction dredger: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads.

Working site of sand suction dredger: sea, port, lake, and river.

Soil conditions for sand suction dredger: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.

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

An integral hydraulic system includes hydraulic oil tanks, hydraulic pump, hydraulic valve manifold, solenoid valve, hydraulic pipes, hydraulic components, electrical actuator and so on.
