The first largest excavator has been successfully launched in China
、
The progress of science and technology is a sign of the growth of a country. In July 1st, a historic moment, by the Wuhan University of Technology and Weihua group jointly developed the production of a weight 570 tons of large dredgers in Wei Hua group to come, to fill the gaps in the type on the machine.
Located in Changyuan County, Weihua Group Co., Ltd. is a large equipment manufacturing enterprise which mainly produces domestic cranes. It is the first time to manufacture this kind of super large dredger. The company's technology and manufacturing personnel to overcome many difficulties, especially for some large steel structure and complex components, such as supporting the cylinder 3.6m * 8.4m * 10.5m * 12.5m, table 1.85M, 30m * 4.5m * 1.8m boom, only on the fixture clamping fixture for designed more than 20 kinds, the more scientific and precise equipment.
The dredger uses 16 technologies, such as horizontal excavation control, underwater mining visualization, super power frequency conversion and multi drive control, of which 3 technologies have reached the leading position in china. This machine is matched with the vessel after assembly, can be used for dredging and cable laying in front of the debris mining etc.. The dredger of steel wire rope maximum tensile force of 70 tons, the maximum dive depth of 60 meters, one can dig 18 cubic meters of debris.
It is learned that the dredger is the national "863 Plan", the national key scientific and technological research projects. This project started production and manufacturing in June last year through market research, market forecast, plan formulation and expert evaluation.
This product is passed by the expert group of the Ministry of science and technology of China. At present, the birth of the largest domestic dredger is finished, and the history of our country has not been independently developed, designed and made by ourselves. Before, the domestic similar products all rely on imports, and the successful development of Weihua large dredger broke the international monopoly, indicating that our country's large-scale dredger has made strides into the world high-end manufacturing field.
A long way in China in the field of dredge development road is still very long, I believe that with this machine gradually into the market, China's development will be on the upgrade project.
