Journey Safety Assessment to Urban Aerial Ropeways Transport Systems Based on Continuous Inspection During Operation

Abstract

This paper proposes a continuous inspection method to assess the journey safety applied to aerial cable vehicles of mass transportation;a type of detachable gondola liftin terms of commercial operation in an urban area, specifically referring to the device coupling assembly on the track rope. The inspection method has been developed on the basis of a continual measurement process of the recorded strain conditions on a principal component of the coupling assembly. The selected component is commonly referred to as moving jaw. The proposed inspection procedure is structured based on the following set of consecutive stages: (i) Downloaded by [Simon Fraser University] at 02:56 17 March 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 characterization of the load states generated by the commercial operation of the system; (ii) definition of the sections of greater sensitivity to the strains caused by the load states, by means of Finite Elements; (iii) development of a measurement system; (iv) calibration of the measuring system with controlled tests; and (v) implementation and continuous records data in commercial operation.

Modeling the Reliability Indicators' Kinetics of a Mobile Ropeway Formed by the Self-Propelled Units

“…The operation of stationary and mobile aerial ropeways is associated with the risk of occurrence and development of emergency situations that lead to a negative impact on the transported people or transported goods [6,11]. Forecasting and analysis of the risk of such accidents in the operation of the main parts, systems or ropeways in general, as a rule, is based on application of the well-known method of fault trees [12][13].…”

Joint optimisation of operation and maintenance policies in an urban ropeway transport systems context

“…since 2004, providing continuous service 360 day a year, 7 days a week, 20 hours a day. The object of study is a gondola-type aerial cable system running on a continuous cycle, see Figure 5(b), mono-cable (simple ring) with a detachable release clamp device (Martinod et al , 2015). Table AI shows the overall technical characteristics of the object of study.…”

“…Daemyung, Korea; La Clusaz, France; Donovaly, Slovakia) (Estepa et al , 2014), but it does not share the tourist purpose of these other examples (Mizuma, 2004). Therefore, the transport system in question is required at high levels of service demand that have not been supported by similar systems, causing highly elevated wear rates (Hoffmann, 2006); it will be hence the aerial cable transportation system with highest level of demand, in terms of wear hours of components and service (Martinod et al , 2015).…”

Maintenance policy optimisation for multi-component systems considering degradation of components and imperfect maintenance actions

“…This numerical application considers the fleet of a massive urban transport system with the following characteristics (Martinod et al, 2015): (i) gondola-type aerial cable, (ii) a continuous cycle, (iii) mono-cable (simple ring), and (iv) detachable release-clamp device (see Table 2). The aerial ropeway system is a télécabine-type system, with a pulling cable constantly revolving in one direction.…”
