on september 29, the crankshaft (12g95me-c10.5) designed and built independently by my country for 24,000teu methanol dual-fuel powered container ships officially rolled off the production line at dalian heavy industry equipment. the marine crankshaft adopts a butt-type structure, with a total length of 23.67 meters and a weight of 539 tons, which is equivalent to the length of a high-speed rail carriage. it is known as the "core of the giant ship" and is a key component used in methanol dual-fuel propulsion engines.

under the huge challenge of having no basis for reference, the r&d team comprehensively upgraded and transformed the processing tooling, carried out bold process innovations and improvements, and finally successfully overcame nearly 10 technical difficulties and completed this " the production of "big guy" is off the production line.

it is understood that this crankshaft has created an important milestone in the localization of my country's large-scale marine crankshafts. from the crankshaft blank, processing and manufacturing technology, to the overall hot assembly and processing, it has completely broken the long-term monopoly of foreign large-scale low-speed marine crankshafts in china. make the dreams of several generations of "china's national machinery and machinery" and "china's national machinery and machinery" become a reality.
