Large marine crankshafts are crucial components of marine engines and essential for large vessels. HDM produces half-built-up crankshafts for MAN series 50–108 and Wartsila series 52–96 marine low-speed diesel engines, with a designed production capacity of 150 large crankshafts per year. HDM has achieved localization of these crankshafts, addressing the bottleneck issue that previously hindered the development of China’s shipbuilding industry, thereby contributing to its advancement.
