60 CBM Grab Dredger for Sale

The overall performance of the machine is stable and easy to operate. The three imported Mitsubishi diesel engines with a power of 1890kW are powerful and have a very low failure rate to ensure the efficiency of the whole machine. The machine drives the transfer case through the diesel engine to drive the oil pump to power the entire system. The oil pump and motor in the system adopt German Rexroth products, and the proportional control flow reversing valve group adopts world famous brand products such as Rexroth and SUN. The main crane and the auxiliary crane are driven by the diesel engine-hydraulic drive, the proportional control flow reversing valve group and the electronic system are integrated and controlled by the PLC to control the lifting speed with stepless speed regulation, and the energy release during the lowering is well solved. It can realize                deep   excavation,  deep   excavation,  hovering,   and semi-automatic dredging. The depth of the excavation of the unit can be grasped by the sensor signal reception on the reel. The variable amplitude system and the slewing mechanism are also controlled by diesel engine-hydraulic drive, which has good performance and reliability, and uses the grab and the weight to automatically lower the bottom.

This dredger is the largest bucket grab dredging crane controlled by the fully hydraulic system in China. It breaks the monopoly of Japan’s SKK on this market. At present, the self-weight and the world of buckets are ranked second. The weight and function of the free-falling weight hammer are the first in the world. It can effectively cope with the world’s largest displacement wreck and the hardness of rock above 50 MPa.
