Product Description

A Grab Dredger picks up seabed material with a clam shell bucket, which hangs from an onboard crane or a crane Barge, or is carried by a hydraulic arm, or is mounted like on a dragline. This technique is often used in excavation of bay mud. Most of these dredges are crane barges with spuds. The Grab Dredger is the most common used dredger in the world, especially in North America and the Far East. It is a rather simple and easy to understand stationary dredger with and without propulsion.Grab steel marine dredgers

Advantages of our grab dredgers
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.

4.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.

5.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.

6.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.

7.Depth correction system:
Which is very important in dredging management system. When the grab according to work requirement set by the depth
of the dredging sank to the bottom, gran dredge rwill swing, boom luffing and tilt by hull, the influence of the change in the
tide heights, cause errors in the dredging depth, this device can be caused by the impact on the error correction, ensure
the accurate of the grab dredging depth of the water.
