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.
