Advantages of large cutter suction dredgers

 1. Cutter suction dredgers are widely used and can be used in rivers, lakes and seas for dredging, channel excavation, and land reclamation. In special circumstances, the installation of high-power reamer equipment on the cutter suction dredger will allow exploration of rock formations such as basalt and limestone without blasting.

2. The cutter suction dredger is economical. Excavation and transportation of materials can be completed at one time, without the need for other ships to cooperate with, transfer multiple times. The relative engineering cost is lower.

3, cutter suction dredger operation efficiency, output value, pump distance. The large-scale cutter suction dredgers can reach thousands of cubic meters per hour; the silt or rock fragments can be pumped out of a few kilometers by strong power through mud pumps and sludge discharge lines.

4. The cutter suction dredger is simple and easy to operate. The cutter suction dredger relies on the trolley of the ship to position and step the steel piles, and uses the reamer arm frame to measure both the steel cable and the anchor fixed in the groove and the two anchors, relying on the traction of the hinged vehicle, and the hatchback swings and cuts the sand and sediment. The material is operated under a certain control swing angle, and the wrung material is pumped to the stacking field through the mud pipe. The stepping of the dredging vessel is alternated by two piles, striding forward.

5. The large-sized cutter suction dredger has a self-propelled system and can be self-propelled when it is moved. Most small and medium-sized dredgers are not self-propelled and are towed by tugboats. Small and medium-sized dredgers can be planned and built to be assembled, transported by land to the site, and can be used after being assembled.
