Marine Crank Shaft

　　DHHI Group has a modern workshop with an area of 24,000 m2 for the crankshaft manufacture and nearly 30 units of advanced NC machining equipment as well as other sound facilities.

Products cover a MAN series of Type 50 to 108 half built-up crankshafts and a Wartsila series of Type 52 to 96 half built-up crankshafts of low-speed marine diesel engines. The design capacity is 150 large crankshafts per year. DHHI achieved the localization of half built-up crankshafts of low-speed marine diesel engines, and overcame the “bottleneck” problems that restrict the development of Chinese shipbuilding industry, thus making a contribution to promotion of the development of China’s shipbuilding industry.
