Lock system to lift 10,000tons ship!

The five-stage ship lock system at China's Three Gorges Dam lifts and lowers 10,000-ton vessels step-by-step over a vertical water-level differential of 113 meters (370 feet).How the Ship Lock System WorksWater Staircase: The system uses five consecutive watertight chambers. It acts like a giant water elevator moving in stages.Filling and Draining: Valves open and close to gravity-feed or drain water into each chamber. Ships rise or drop to match the water level of the next segment.Capacity: The massive chambers accommodate large commercial cargo ships and multi-vessel convoys up to 10,000 tons.Transit Time: Navigating all five stages takes roughly 3 to 4 hours.Alternative: The Ship LiftFaster Option: A separate vertical Three Gorges Ship Lift handles smaller vessels up to 3,000 tons.Single Lift: Instead of stepping through five chambers, it hoists a water-filled basin straight up or down 113 meters in about 40 minutes.
