Mechanical Level-cut Clamshell grabs
This type of grab is specially designed for dredging of polluted mud. The advantage compared to a normal dredging grab is that it has low turbulence when lifting the grab, it has a bigger foot print and because the grab will close almost horizontally it is possible to remove mud from the bottom very accurately. The grabs are manufactured of high wear resistant steels.
By positioning the grab you can remove only the required layer of polluted mud without taking any non polluted mud. The grab is suitable for dredging mud with a density up to 1.5 t/m3.
These grabs can be manufactured in a 2 rope or four rope execution.
