High energy efficiency with counter weight balalnced 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)
Hydraulic grab bucket for hard soil
We made hard soil dredging possible by installing 130 ton self-weight bucket with max. pressure 34.3 MPa hydraulic unit.
High oil temperature can be prevented by cutting off hydraulic pump at set pressure when pressure gets too high.
