Grab Dredger/Grab Bucket Sand-Excavating Ship/Rivers Excavatorse
Special Grab Bucket Dredger, 70t Rivers Excavators
The deck crane is a kind of ship's hoisting equipment usually set
in the cabin deck which contents high technology of electricity,
liquid, machine integration of deck. With the advantageof easy
manipulation, impact resistance, good performance,safety and
reliability, it can make a good use of the limited space of port,
yard and other places. It has high working efficiency and good
adaptability to the goods, especially for the dry bulk cargo

Our dredger advantages
1. PLC and Visual simulation system:
which make hoisting more simple and easy operation,realize fixed
and pvikut digging.
2. Heavy digging control system:
which greatly improve dredging efficacy of the , make dredging work
more smoothly and reduce drivers operating intensity.
3. Fixed dredging depth control system:
which greatly improve underwater dredging work quality,make
dredging depth be fixed and avoid over dredging waste.
3. Satellite positioning dredging construction system:
Which will do timely determination of hull and grab position,
rapidly and accurately display the excavating position of ship and
grab trajectory, ensure high efficiency, high precision of the
dredging engineering construction.
4. Flat digging control system
Which can store several type grabs’ work processing procedures for
the users to change grabs in accordance with work. By using such
flat digging system, we can not only make digging face level to
meet the dredging project quality requirements, but also can
relieve fatigue of drivers.
What’s more,our accuracy of flat digging is 15 ~ 25 cm, better than
all similar products’ accuracy of 50 cm at home and abroad. meet
all kinds of marine waterway dredging engineering.
5. Mining depth and grab opening control system
Our grab dredger is equipped with a data depth gauge and simulated
bucket opening degree gauge , which indicating working depth and
grab opening degree.
6. Depth correction system
