The JLCSD-150 Cutter Suction Dredger of steel construction, non self-propelled, dismountable type, is able to berth and dredge at any waters both in the coastal area and inland rivers, with similar conditions to that in navigation area “A” or below the “A”-line specified in code for inland river steel engineering ship manufacture of P.R.China.
The dredger can be used to excavate and transport cohesive sediment below the class ? specified in code for dredging engineering construction technique issued by Ministry of Water Resources(MWR) of P.R.China.
In the course of technical designing, we have considered special requirements for local tropical climate conditions such as meteorological and waters distributing state etc.
It’s hull consists of a main pontoon and two side pontoons, which is to be easy to dismantle or mount for transportation by road, rail or water, and is to be easy to reassemble at project site.The engines and dredge pump are located in the center pontoon,the 2 side pontoons serve as fuel bunkers,ballast tanks and storage tanks.
The dredger is powered by diesel engines. The main diesel engine is to drive the dredge pump, and in the free part of the engine, one set of power distributor is equipped, to supply power for all other equipments such as cutter, swing and ladder winches, and the spud rams etc.
The spacious control cabin is ergonomically designed with 360 degree view. All the operation buttons, swifts, indicators, gauges are equipped on the control desk. Only two operators can control all the dredger in the operation room.
The dredger is painted by 4 layers of marine paint to protect from the corrosion. The ZINC anode can be used to give better anti-corrosion function.
1. Qingzhou Julong Dredging & Mining Machinery Co.,Ltd. is a dredger manufacturer and exporter, but not just trading company. In such case, we can guarantee the products quality, delivery time and after-sales service. Also better price will always be available. 2. Customized designs will be made based on customers' project requirements. Our engineers are all experienced in ship designs for many years. The cooperation with China leading ship design institutes and professional colleges help us to ensure the design quality. 3. All the Julong dredgers are built by skilled workers and inspected strictly to assure the high quality and durability. Each finished dredger will be fully tested before delivery to make sure it work smoothly when delivered to customers. 4. Best parts will be used for the dredgers, like world famous Cummins engines, Shijiazhuang pumps, Hangzhou gearboxes, Simens PLC control system. 5. Hydraulic system is one of the most important parts of cutter suction dredgers. The cutter head, ladder winch, swing winches, spud or spud carriage are driven by hydraulic motors for higher efficiency and durability. Reputed brands are used for the other hydraulic parts like hydraulic pipes, hydraulic pumps, hydraulic valves. 6. The dredgers are dismountable. So they can be disassembled and assembled easily. Thus it is convenient for the transportation by road, rail or water. 7. Professional engineers will be sent to the project site to insist the customers on the installation, commissioning, testing of the dredgers and training of operators. 8. The main parts of Julong cutter suction dredgers are all imported ones or assembly of imported parts so that the buyer can purchase the spare parts easily, like the Cummins engine, the Shijiazhuang pump,Siemens PLC control system, Schneider or Omron electric system.
These dredgers are highly flexible in use. The modular structure and tight design allow the dredgers to work even in shallow river and waterways. Different arrangements of sand pumps and cutters make sure the dredgers can work in different circumstances like sand , stones, mud , etc. In container or bulk ship. Our field engineer will guide to assemble the machine at your working site and train your staff.

For ship inspection certificate, we can make the following dredgers: 200M3,400m, 3800M3,1200M3,2000M3,3000M3,3500M3,5000M3. The company can make dredgers of the following depth: 2M, 5m, 10m, 15m, 20m, 25m, 35m. The company can make the following transport mileage dredger 100m, 200m, 500m, 800m, 1000m, 1500m, 2000m, 2500m, 3000m. Our Dredger and desilting vessel are customized according to customer's requirements and construction conditions and environment. The product type is different, the product price also can have the different concrete negotiable. The work flow undefined first uses the winch arm rest two test cables and the anchor traction fixed to the two tests to fix the cutter suction dredger with the positioning post behind. The cutter is placed in the underwater mud layer (see figure 2) by operating room button control, the cutter head is rotated, the riverbed mud layer is cut and stirred (see figure 3) , and the mud-water mixture is pumped up through the suction pipe (see figure 5) through the suction pipe (see figure 4) , the mud-water mixture is piped (see figure 6) to the desilting site (see figure 7,8) for desilting.
Cutter suction dredger is widely used. It can be used for dredging, river and pool excavation, river dredging, channel excavation, reclamation by pumping filling, etc. in rivers, lakes and sea
China Classification Society (CCS) and foreign classification societies, completes the task of new ship building in a shorter time better, and provides the construction side with real-time technical operation guidance.
