More than 220,000 tonnes of cargo have been carried by the world’s largest shiplift at the Yangtze River’s Three Gorges Dam in central China’s Hubei Province since September, China Three Gorges Corp. announced on Tuesday.

A total of 886 ships, carrying 220,415 tonnes of cargo and over 7,900 passengers, have passed through the dam’s ship lock via the shiplift between September and mid-March.

According to the company, the shiplift has reduced the average time to pass the dam from over three hours to just one hour.

The shiplift, the largest and most sophisticated of its kind in the world, features a ship-chamber, which has a container that is 120-meters long, 18-metres wide and 3.5-metres deep.

It is designed to transport small and medium-sized ships, with a maximum displacement of about 3,000 tonnes.
