The Bailong Elevator, any summary thanks?

The Bailong Elevator, also known as the Hundred Dragons Elevator, carries tourists 1,070ft (330m) up the side of a massive sandstone column in a mountain range in China 's Hunan Province .

Riding the glass lift, which carries up to 50 people at a time or1,380 an hour, offers jaw-dropping, not to say vertiginous, views down to the bottom of the rocky mountain range in the Wulingyuan area of Zhangijiajie.

You can see the structure in link given below.
