摘要: Abstract Monitoring of the rope condition and lengthening its lifetime - it is a requirement each user. The operator can get information about current by using method non-destructive testing (NDT). Parameters (information) gained from testing, such as number distribution fractures, diameter winding height, determinate further operation rope. However, possible to observe trends in monitored parameters, if NDT inspections are performed regularly. We made an attempt employ these create prediction model parameters changes development determine well. aerial cableway subject monitoring. During regular checks was evaluated well monitoring trend ruptures increase carried out. It found that showing practically growth fractures particular period operation. course generated gradually; shape quite lot resembled bathtub curve known maintenance practise. arm this general having exponential course. This assumption created base subsequent periods. Besides record fracture for next two years after every new measurement. gradual comparison real with supported (confirmed) prognosis course; enabled setting advance date deployment. creating very important because utilization terms safe cableway. past track regularly coordinated six In operating on changed or working operator. establishment based prolonged up 13 years.
