Product Description
China Grab Derdger with Low Price for Sale
Operation principle:
with rotational arm and cable,the dredger can be equipped with different type grabs.Suitable for grabbing clay,sludge,incubated stone,not good function for fine sand ans silty sand.
Rated lifting capacity: 70t
boom: 30m
Rotary radius: 15~23.5m
Boom working angle: 71°~51°
Suitable grab: 18m³×45t(dead weight)
Grab cable: 44ZAB-6×36WS+IWR-1770
Rotary speed: 1.2r/min
Luffing time: 60s
Boom luffing cable: 34-ZAB6×36WS+IWR-1770
Max lifting height: 10m(up water level)
Max digging depth: 50m(down water lever)
Grab lifting speed: 0~60m/min
Hoisting Mechanism:
Structure: Motor, Coupling, Brake, Reducer, Drum Group, Bearing, etc;
Feature: Motor through coupling and reducer drive to Launch and recovery wire rope drum group,to realize the grab bucket hoisting, declining, open and close,dig etc action.
USES: mainly used for digging clay, silt, gravel soil, gravel soil and weathered rock;
Luffing mechanism:
Structure: Motor, Coupling, brake, reducer, reel drum and bearing pedestal etc.
Function: The motor through the coupling, reduce driven the reel drum launch and recovery the wire rope, adjustable the jib beam working angle, control the grab working range.
Towing mechanism:
Structure: Mainly compose by motor, limit moment coupling, brake, vertical planetary reducer, small gear, big gear ring.
Function: The motor through the coupling, reduce driven the small gear, the smal gear and big gearing ring engage, realize the grab bucket rotating movement.
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.
