Description

Technical Field

[0002] The zip-line is the original form of the passenger aerial ropeway. In the ancient southwestern mountainous areas of China, there were many river crossings that used bamboo ropes or rattan ropes to cross the river, which were called "zuo" or "hanging crossing". In the Ming and Qing dynasties, many such non-powered primitive ropeways were built in the southwestern region and can still be seen in remote mountainous areas. At the same time, the zip-line, as a new entertainment project, is called an extreme sport. Passengers wearing flexible slings are suspended under the sliding trolley and slide rapidly from a high place to a low place by using gravity along the two obliquely pulled steel ropes as tracks.
