Dredging Clamshell Grab

Multi-material adaptability
It can dredge a wide range of materials, including seabed silt, mud, sand, gravel, crushed stone, and boulders, and can even handle weathered rock and dense crushed stone (a heavy-duty grab bucket is required).
It is suitable for full-range operations across a range of soil types, from soft to hard layers, particularly in areas that are challenging for trailing suction dredgers to access, such as harbors and channel bends.
Precise operation capability
It can accurately remove underwater obstacles (such as old revetment facilities and reefs), and is suitable for construction in narrow or complex terrains.
It supports layered excavation, and the grab bucket lowering depth can be adjusted according to the thickness of the mud layer (such as soft soil or hard soil layer below 2 meters).
