Model Number: Grab Dredger-18 M-B Brand Name: Weihua Key Specifications/Special Features: Grab dredger boats are used for dredging sludges in waterways, harbors, lakes and more as dredge and drainage engineering shipsGrab dredger boat mainly consists of hoisting mechanism, luffing mechanism, slewing mechanism, rigging hook device, A-frame, rotating platform, rotating support, booms and grab bucketsThere are several control systems provided to improve dredging efficiency and accuracy as following (includes but not limited to):1. PLC and visual simulation systemPlC system can greatly improve and facilitate operation of speed control and halt with load in the mid-air, visual simulation system is able to achieve visualization and intellectualization in depth keeping digging and horizontal digging2. Depth keeping digging systemThis crane is provided with depthometer, according to which the operator is able to set dredging depth to improve the dredging quality and avoid wast of over excavating

3. Satellite positioning dredging construction management system
This system is is used to indicate location of the hull and working track of the grab bucket anywhere and anytime to ensure high efficiency and accuracy of dredging construction quality

4. Horizontal digging control system
This system is able to store several kinds of grab working processing program and provided with manual input type depth correction function. Thus smooth working faces are able to achieve

5. Depth correction system
While working, the grab can be affected by dredger slewing, luffing hull tilting, depth correction system can revise the tolerance
