The amphibious dredger is a special engineering vehicle that combines land mobility with floating capability on water. It overcomes the limitation of conventional excavators or dredgers, which can only operate in a single environment. This multi-functional dredger can efficiently perform dredging, silt removal, and environmental remediation in challenging conditions such as swamps, wetlands, shallow river and lake areas, ponds, drainage canals, and intertidal zones – where conventional machinery cannot easily access.
