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
