Improvement of Windproof Performance of Ropeway Carriers (1st Report, Analysis of Accidents Due to Wind and Wind Tunnel Experiment of Real Carriers)

In order to increase the safety and reliability of ropeway systems, it is extremely important to improve windproof performance of carriers since the excessive swing of the carrier by wind may lead to a serious accident such as a collision with the columns. As the first step of studying improvement of windproof performance of ropeway carriers, this paper presents analysis results of accidents due to wind and results of wind tunnel experiments of real carriers. Analysis results of accidents clarified features of ropeway accidents due to wind. Results of wind tunnel experiments showed aerodynamic characteristics of two typical monocable carriers.
