Hydraulic Level-Cut Clamshell Grabs - The solution for polluted mud.
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 is closing almost horizontally it is possible to remove mud from the bottom very accurately.
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.
The grabs can be executed with:
- Hydraulic rotator for 360˚ rotation
- Hydraulic 360˚ rotation by means of slewing ring and hydro Motor
The grabs are manufactured of high wear resistant steel and can be manufactured in any execution weight and capacity you require.
A suspension link for connection of the grab to the crane can be manufactured according to your requirements.
