1). Great Adaptability. The cutter suction dredgers can be widely used in river, lake, sea, reservoir and so on for sand/mud dredging, waterway cleaning and reclamaition work.
2). High Efficiency. The cutter suction dredgers can dredge and discharge sand/mud at the same time without other ships for transportation. So the cost will be much lower and they can reach big production capacity of several thousand cubic meters per hour and also several thousand meters discharge distance.
3). Easy Operation. With hydraulic system and PLC control system, all the dredgers operation can be done in the operation cabin.
4). Quick disassembly and assembly.
5). Customized designs will be made based on customers' project requirements. Our engineers are all experienced in ship designs for many years.
6). 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.

8). 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.
9). The dredgers are dismountable. So they can be disassembled and assembled easily. Thus it is convenient for the transportation by road, rail or water.
10). 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.
