Powered pontoon bridges—60-metre steel giants dubbed “Rescue Carriers”—became the unlikely heroes when catastrophic flooding engulfed Guigang City, Guangxi, in early July. As torrential rains sent water levels skyrocketing to 7 metres at the Xinjiang Education Park, 30,000 teachers and students found themselves trapped in a rising nightmare.

But these floating lifelines didn't wait for the waters to recede. Each capable of ferrying over 300 survivors per trip, the high-tech platforms sliced through submerged streets, wove between half-swallowed buildings, and navigated narrow, debris-choked passages with surgical precision. The result? After three harrowing days and two nights, more than 6,000 stranded students and staff were evacuated in just 20 hours by the giant rescue platforms, proving that cutting edge engineering technologies are truly life-saving.
