Features

High Efficiency: With integrated dredging, transporting, and discharging functions, our vessels can operate continuously, resulting in higher production efficiency.
Precise Dredging: Equipped with Siemens PLC control systems, the vessel can perform precise dredging in specific areas with accurate contouring using the cutter head control and positioning system.
Strong Adaptability: Capable of working in various soil conditions, our dredgers can handle different types of cutters to dig sand, sandy loam, silt, and more. They perform well in calm inland rivers, lakes, and coastal ports with low currents and minimal waves.
Cost-Effective: Our dredgers complete excavation and transportation in a single step, eliminating the need for multiple vessels and reducing overall project costs.
