Bailong Elevator, Glass double-deck elevator in Wulingyuan, Zhangjiajie, China

The Bailong Elevator is a glass double-deck elevator built onto a quartz sandstone cliff in the Wulingyuan area of Zhangjiajie. It has three transparent cabins, each in two levels, running on an exposed steel derrick: 154 m inside a shaft in the mountain and 172 m on the outside lattice. The cabins are made of acrylic glass.

Construction finished in 2002 after crews carved tunnels and shafts directly through the natural rock formation. This project significantly improved access to the upper areas of the canyon.

The name Bailong means "Hundred Dragons," and the Chinese name 百龙天梯 is rendered as "Hundred Dragons Heaven Elevator." The three double-deck cabins are made of acrylic glass, and the lift was supplied by Kone and installed by Weifang Longer, a Chinese joint venture of Germany's Langer. It carries visitors directly to Yuanjiajie, in the core of the Wulingyuan scenic area.

Three double-deck cabins run the shaft; after the 2013 upgrade each carries up to 64 people at 5 m/s, covering the 326 m in about 1 minute 28 seconds. Of that height, 154 m lies inside a tunnel in the rock and 172 m on the exposed steel derrick. The cabins reach the Yuanjiajie area at the top directly.

Of the 326 m of travel, 154 m runs inside a shaft bored through the sandstone and 172 m on the exposed steel derrick fixed to the cliff. The cabins' glazing is acrylic glass, and the three lifts were supplied by Kone and installed by Weifang Langer, a Chinese joint venture of the German firm Langer.
