Sealed hydraulic grab bucket system
We installed the electric hydraulic unit in the bucket, which takes the power from the vessel with cable. So it has more grabbing force due to hydraulic and more dredging power due to its whole bucket weight, enabling dredging hard soil easier, unlike conventional grab bucket.
High energy efficiency with counter weight balanced grab hoisting system
It is adopted with a balance equation grab hoisting system.
The counter weight that is balanced with the grab weight is connected with crane's hoisting wire.
So it needs only the power for the soil's weight during hoisting the grab bucket in dredging.
According to our survey, only 60% of energy is necessary compared to the conventional grab dredger that winch has to hoist both bucket and soil's weight. (Patented)
Speedy shift by 2 spuds system
She has a spud system for shifting. One spud is in the middle of the vessel and the other in aft.
With them, she can shift without assistant of push boat or anchor wire.
The system can be controlled by one operator from the bridge. (Patented)
Dredging execution management system
With RTG-GPS and special soft ware for operation, we can easily specify dredging area and check the history.
