The first large-scale marine crankshaft manufactured by Dalian Heavy Industry·Holding Group Co., Ltd. was officially launched at the end of 2007 by Dalian Huarui Crankshaft Co., Ltd. through the joint inspection of classification societies and users. This indicates that Dalian Heavy Industry·Zhangzhong Group has already possessed the mass production capacity of large marine diesel engine crankshafts with independent intellectual property rights, which will effectively alleviate and solve the crankshaft bottleneck problem that restricts the development of China's marine diesel engine and shipbuilding industry.
Large-scale marine crankshaft is a key component of marine diesel engines. It has large weight, high precision, demanding performance and complicated manufacturing process. Its market is basically monopolized by a few countries such as Japan, South Korea, Czech Republic and Spain. In recent years, there has been a global shortage of supply. In the shortage situation, prices continue to rise, and delivery time is getting longer and longer, which has led to the phenomenon of “ships (ship diesel engines), machines and other crankshafts†in shipbuilding in China, which has become a constraint to China’s machine building, shipbuilding capacity and shipbuilding industry. The key issue was thus listed by the state as one of 16 major technical equipment research and development projects.
The first crankshaft of Dalian Huarui Crankshaft Co., Ltd. was officially launched on December 29, 2007. The 6.7-meter-long, 41-tonne crankshaft will be used on the 50,500-ton oil tanker exported by Italy.
Song Jiajing, chairman and general manager of Dalian Heavy Industry·Hangzhou Group, said that the crankshaft is an important symbol of the national shipbuilding industry. The mass production capacity of marine crankshafts with independent intellectual property rights formed by Dalian Heavy Industry and Crane Group will be the world for China. The development of the first shipbuilding power provides strong support.
