Overviewof HUALI

HUA LI,built in April 2014,is a multifuctional vessel for wreckremoval and dredging.It is particularly suitable for salvaging deep-water sunkenships in harsh sea conditions with high winds and waves, and is suitable for self-propelled mobilization in any sea area in the world. The vessel is driven by propellers and equipped with two 360°rotary cranes,mainly engaged with wreck salvage and dreging,with advantage over its competitors in the industry deep-water salvage and dredging.

60m³ Grab Crane

The dredging crane is 360° full rotary, capable of hoisting, salvaging,dredging and smashing. It can undertake highly difficult hard engineering works under deep water environment.

The working temperature is between -20°C to 40°C(water temperature:0°C~28°C), it ensures safety work under maximum wind speed 20m/s (gust).

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 in fixed place, hovering, and semiautomatic 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 slewing mechanism are also controlled by diesel engine-hydraulic drive, which has good performance and reliability, and uses the grab and hammers which can fall to the bottom automatically.

This machine is currently the most self-developed fully hydraulic system controlled grab bucket crane with the maximum bucket capacity and strongest excavation force. It can excavate up to 200meters water depth, which is obviously superior to the Japanese SKK dredging crane. At present, the crane gripping force, the weight of the grab and the bucket capacity rank second in the world. 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 (170,000Tons) and the hardness of rock above 50 MPa.





200T Crane

This dredging crane is a 360 °degree fully rotating grab bucket crane which has the function of dealingwith complex marine environment and is matched with double-peel and six-peel grab buckets for emergency repair.

The working temperature is between-20°Cto40°C(water temperature:0°Cto28°C),it ensures safety work under maximum wind speed20m/s(gust).
