Species8472, I'm an American, living in the United States. I know what you mean, though. I'm praying that the rescue teams in China have access to this type of equipment.
I copied those photos of rescue equipment from an Emergency Rescue conference which was held in Indianapolis, Indiana earlier this year. Last year I attended a rescue demonstration where firemen demonstrated one of the lifts. When it was deflated, it looked like a simple rubber mat. When inflated, it was capable of lifting many tons, enough for a rescue in a collapsed building.
We have a new air bag (Zumro NT)that we like a lot better than the "square bag" They can attach together and stack several layers high.
