Cable car systems are predominantly used in the Alpine Region for the transportation of passengers and goods. During operation, their components are subjected to environmental influences as well as to static and dynamic loads. Even if standards, measurements, experimental tests, periodic inspections, and maintenance are considered, a component failure can not be entirely excluded. It is for that reason that cases of damage in the cable car industry are clarified based on systematic analyses aiming at prevention and an increase in security.The approach for the identification of the underlying causes of a case of failure is presented using the example of a spectacular incident in 2004 where all external profile wires of a support cable of a 100 passenger aerial tramway broke during operation.A precautionary and thorough preservation of evidence, detailed examinations of the subject components, clarifications of the operating history of the system, as well as an eventual identification of a probable damage process supported by examination findings are essential steps of this approach.The findings of such evaluations are the basis for recommendations regarding testing and construction of further systems, their operation, maintenance, and inspections with a focus on damage prevention.
