Core Points - The Three Gorges Ship Lift has been operational since 2016, facilitating nearly 50,000 vessel passages and transporting over 19 million tons of goods, while also receiving more than 2 million tourists, making it a crucial component of the Yangtze River Economic Belt development [1] - The annual maintenance inspection, lasting 35 days, is the fifth planned shutdown since the completion of the ship lift, aimed at eliminating equipment defects and enhancing operational reliability and safety [1][3] - This year's maintenance focuses on systematic repairs, particularly on the synchronous shaft, which is critical for the transmission system and affects the overall operational precision of the ship lift [3] Maintenance Innovations - The introduction of a large-scale laser cleaning device for the nut column, which is part of the safety system, significantly improves cleaning efficiency compared to previous manual methods, addressing issues of space, efficiency, and safety [5] - Extensive testing was conducted to optimize the laser parameters to ensure effective cleaning without damaging the surface roughness of the components [5] Operational Adjustments - During the maintenance period, vessels meeting the technical requirements can still pass through the Three Gorges double-line five-level ship lock, ensuring continuity in navigation and stability in shipping operations [7] - The Yangtze River Three Gorges Navigation Administration has proactively communicated with shipping companies to facilitate transportation planning during the maintenance period [7]
