NOMOGRAMS FOR OPTIMIZING CARRIER CABLE CHOOSING FOR GRAVITATIONAL CABLE TRANSPORT INSTALLATION

Cristina SESCU-GAL, Horia Mircea ALĂMOREANU

Abstract


The paper refers to installations known as ‘ziplines’ which are gravitational cable transport installations used in recreational areas; their route is descending and only one user is allowed on the route - a single mobile load. The calculation of the sizing of the carrier cable will be done by tests, because its mass as well as the optimal arrow are not known a priori. This paper presents a solution for sizing the carrier cable based on nomograms that the designers can draw themselves according to the particular data of the respective installations.
