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

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

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

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

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

A. Hull Welding

2. Carbon-dioxide arc welding and Submerged-arc welding.

3. Tightness test and inspection

B. Deck machinery installation.

C. Main engine and auxiliary engine location installation.

D. Hydraulic system installation.

1.  The pickling , phosphating treatment of the hydraulic pipes.

E. The electrical installation

F. The Whole machine test.

Design__Cutter suction dredger design meets the requirements and regulations of CCS, BV and ABS , which are belonging to IACS.

The technology refer to Holland IHC, and dredger can be custom made according to customers' requirements.

Chief engineer Gan attended the “Local cutter dredger design study on IHC Beaver” in 2000.

Steel plate__ Raw material is marine use material which meets the requirements of CCS., and all plates are under sand blasting process.

Hydraulic system__Hydraulic oil pipes made by pipe bending machine to decrease the welding points so that can keep system stability. When the oil pipe finish, should be acid picking and  phosphating treatment to keep whole system clean and stability.

Dredging 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 anti-friction bearings are from Japanese brand NSK.
