We manufacture the sea sand dredging cutter suction dredger is self-propelled or non self-propelled,portable sea sand dredging cutter 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 sea sand dredging cutter suction dredger are as bellows: 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 sea sand dredging cutter suction dredger; at the end the slurry will be discharged by pipeline on land to the required place.

This Weifang Jin Meng sea sand dredging cutter suction dredger is equipped with horizontal shifting devices, cutter ladder lifting devices, spud devices, deck crane and so on. It can also be equipped with anchoring poles and trolley devices. Generally, it has functions on dredging, conveying and discharging of mud or sand. It can produce certain amount of vacuum by the centrifugal pump.
Design
Our sea sand dredging cutter suction dredger is designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee they are well-designed and practical.
Cummins Engine
The sea sand dredging cutter suction dredger is equipped with world famous powerful Cummins engine, which are famous for its durability, lower oil consumption, standardized accessories and easy maintenance.
Hydraulic system
The most important parts of sea sand dredging cutter suction dredger and wheel bucket 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.
Detachable Structure
The sea sand dredging cutter suction dredger is detachable, so it is easy to transport when delivering or moving from one working site to another.
Shijiazhuang 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.
Cutter head
For one cutter head, there are 5 blade, 8 teeth equipped on one blade. There is material High chromium. for easy-wearing proof.
Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.
1.Sea sand dredging cutter suction dredger will be equipped with pipelines for solid discharging work.
2.Pipelines usually include three parts: Pipes, floaters and rubber hose.
3.There are three kinds pipes(Steel pipe, HDPE pipe and self-floating pipes) for customer to choose according to the discharged solid material.
4.Customers can buy pipes by themselvies or from us . If customers have special requirements, the pipelines can be custom made by suppliers.
5.About shipping package: pipelines will be shipped by 40" HQ containers .
6.Kind reminder: customers shall buy extra pipelines as spares.
