China hydraulic system cutter suction dredger, sand river pump dredger
Cutter suction dredge is widely used in dredging project.It makes use of a cutter head equipted around the front of the water suction tube to loosen and cut the mud to be dredged. It pumps the dredged material via the mud flowing pipeline to the pile. The digging,transpating and discharging progress can be carried out at the same time.It's of high work efficiency and low costing.Cutter suction dredge is a good choice for underwater dredging.

Working theory :
The hull uses dismoutable and box-like structure , which 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 discharge of mud or sand. it can produce certain amount of vacuum by the centrifugal pump.
Generator sets supplies electricity for lighting and emergency use when it doesn’t working.
Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.
The dredger is moved by alternate swing of the spuds. The spuds are lifted by the hydraulic cylinder.
The shifting winches, cutter ladder and lifting winch are driven by the hydraulic motor.
The hydraulic oil pump is driven by the auxiliary diesel engine.
The design, construction, quality inspection is according to the standards and regulations of CCS. The hull, machinery equipments and other spares are at the requirements of CCS. The hull is square, cross keel, which is full welding steel structure. And authorized by CCS.
Applicability : To pass low bridge easily, the controlling room and rest room are dismountable. Connecting parts for cabin room and deck are easily dismounted joints,.
Construction: it consists of three pontoons: one main pontoon and two side pontoons. The pontoons are connected by the connecting pieces and tightened by high intensity bolts and nuts.
Working site of cutter suction dredger: sea, port, lake, and river.
Soil conditions: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on.
1) For sand dredging , river maintenance,etc
2) Reliable hydraulic system
3) Fresh water engine cooling system.
4) Solid structure and top quality parts
5) Ideal dredging depth and discharge distance
6) High efficiency and Great production
7) Spare parts and floating pipe available
8) Low energy consumption
9) Efficiency fuel consumption
10) Simple to assemble , operate and maintain
11) Transport by road , rail or sea
12) The dredger is mainly used in the coastal , river, channel , reservoir , to dredge and backfill for the harbor construction.
The technical options of the dredgers are customized--up to the customer's requirement and the working environment.
Quality Warranty :
Every cutter suction dredger is built by skilled workers and inspected strictly to assure the high quality and durability. Each finished dredger will be tested in our testing center to make sure it works smoothly when delivering to customers.
Will provide 12-months warranty for the quality of the main parts: Diesel engines, generators, gear boxes, dredge pumps, Hydraulic system.
1) 12 months manufacturing warranty on all new installed component parts.
2) 12 months warranty on hull and all fabricated parts.
3) Wearing parts are not included.
During the warranty period , We will provide free parts and on-site technical guidance . After the warranty period, We will provide free and on-site technical support quickly, if the ship-owner need. But if the dredger need replacement parts, the cost paid by the owner.
The cutter suction dredgers are detachable, so it is easy to transport when delivering or moving from one working site to another.
Training and installation :
Our experienced installers will arrive at the construction site to guide, teach and training your staff to debug and operate the dredger until they can operate skillfully by themselves.
