Zhenhua Heavy Industry successfully developed the first locking system

Recently, Shanghai Zhenhua Heavy Industry (Group) Co., Ltd. successfully developed the first set of locking system independently developed by Hong Kong-Zhuhai Ore-plating and leveling ship, and passed the prototype test and obtained the qualification certificate issued by China Classification Society (CCS). The key equipments such as hydraulic, electrical and worm gear jacking devices in the system were independently developed by the company and obtained a number of national patents. They successfully broke the foreign monopoly, and the company successfully entered the international few with the system design and production capacity. Of the company.

The locking system will be used for the platform lifting mechanism of the riprap leveling ship of the Hong Kong-Zhuhai-Macao Bridge Island Tunnel Project. After being put into use, the hull load can be smoothly converted from the lifting system to the locking system. The maximum vertical load is 2,600 tons. The efficiency of locking or loosening is high, the operation time is only about 10 minutes (usually about 20 minutes in the industry), and the design life is 20 years.
