my country developed the first 50-ton variable frequency marine crane

       The reporter learned from Wuxi Huishan District Science and Technology Bureau that my country's first self-owned brand 50-ton frequency conversion marine crane developed by Wuxi Jiangnan Ship Equipment Co., Ltd. has passed the inspection of the Bureau Veritas and the official factory inspection recently, marking the possession of The major scientific research achievements with independent intellectual property rights have begun to enter the stage of industrialization.

        According to reports, the 50-ton variable frequency marine crane developed by the company is tailor-made for the Indonesian customer's 57,000-ton bulk carrier "SELDAVINTO", with a lifting capacity of 50 tons and a maximum working range of 36 meters. , the fastest lifting speed is 40 m/min, and the fastest turning speed is 0.82 rpm. It is controlled by a fully variable frequency programmable controller (PLC) and is equipped with a user-friendly human-computer interaction system, which can realize the three actions of lifting, turning and frequency conversion at full load and full speed at the same time, without the use of hydraulic oil. Especially compared with hydraulically driven cranes, the work efficiency is increased by 1.5 times, and the power consumption is saved by 20%, which completely eliminates the hidden dangers of oil leakage, bursting, hook slipping and other accidents that may exist during the use of traditional marine hydraulic cranes. It is understood that the company is a professional manufacturer specializing in inland water, marine ships, military ships, and deck machinery for offshore oil platforms. Due to its emphasis on the introduction of scientific and technological innovation talents and the research and development of high-tech products for many years, it has effectively promoted the internationalization of enterprise innovation. process. The hydraulic cranes, crane cranes, hydraulic windlasses and various special marine deck machinery produced by the company are exported to Greece, Norway, Japan and other places, and a subsidiary has been established in Singapore, becoming a "benchmark enterprise" in the domestic industry. At present, the company has initially reached a cooperation intention agreement with several large domestic shipping companies and foreign users.
