Recently, the riprap leveling ship lifting device independently developed by Zhenhua Heavy Industry and applied to the Hong Kong-Zhuhai-Macao Bridge Island Tunnel Project successfully completed the prototype test. As the first platform project independently researched and developed by the company, the Hong Kong-Zhuhai-Australian riprap ship will make Zhenhua Heavy Industry take the lead in realizing the platform uplifting technology breakthrough in China.
      The main design parameters of the flattening ship lifting system are similar to those of conventional offshore oil drilling platforms, but at the same time, it has the characteristics of Zhenhua Heavy Industry. It adopts frequency conversion control to realize two speed control of lifting platform and pile legs; The herringbone form greatly improves the reliability of the device.
      The lifting system is mainly used for lifting and supporting the offshore jack-up platform. If the jack-up platform wants to “stand up, rise, and pull outâ€, the lifting system is the key. For a long time, the lifting system has been monopolized by foreign companies. The company is brave in innovation, and has overcome the four key technologies of large load lifting mechanism design, high modulus machining of large modulus and large size racks, development of large speed ratio gravure planetary gears and simultaneous control of lifting system (72 sets of motor drive units). .
     Up to now, Zhenhua Heavy Industry has successfully sold more than 600 sets of lifting systems to home and abroad.
