The HID amphibious dredger efficiently dredged in the lake area dredging project, increasing the construction efficiency by over 40%.

The HID-200 amphibious dredger, independently developed and manufactured by HID Shipyard, has successfully completed the phased construction tasks in the lake ecological dredging project. Facing a complex working environment with dense reeds and deep silt, this vessel has achieved continuous and trouble-free operation for 48 hours, thanks to its excellent amphibious passing capability, high-power reamers breaking soil system and efficient mud pumping system. The silt removal efficiency is over 40% higher than that of traditional machinery, earning high praise from customers.

Over the years, this lake area has accumulated a large amount of organic silt, with an average depth of 4.5 meters. Moreover, the lakeshore zone is a typical marshy wetland, making it very easy for ordinary excavators and transport vehicles to get stuck. Crawler equipment also frequently skids and sinks, making it impossible to safely approach the working surface. If the traditional dry method of silt removal is adopted, it is necessary to build a cofferdam for drainage first, which is time-consuming, costly and causes significant disturbance to the surrounding ecology.

HID Shipyard allocated a HID-200 amphibious dredger based on the actual situation of the project. It can drive smoothly and perform parking operations in both mud and shallow water areas.

Its core configuration includes:

- Hydraulic-driven cutter head: Can break hard clay and grass root layers, with high digging concentration;

- High wear-resistant slurry pump: With a maximum conveying distance of up to 1,200 meters, it enables in-situ extraction of sludge and pipeline transportation to the storage yard.

- Remote control + intelligent posture monitoring: Operators can stay away from dangerous areas, making construction safer.

HID amphibious dredgers are widely used in fields such as water conservancy dredging, environmental protection silt removal, wetland restoration, and tailings treatment in mines.
