Analiza uslova i podloge za izbor uređaja za zaustavljanje kod zipline-a

Abstract

This paper defines the basis for zipline arresting devices. Considering that there is currently no legal regulation in Serbia that defines devices for zipline braking and arresting, an excerpt from foreign standards are given in the first part of the paper. This is followed by an overview of existing solutions of arresting systems, as well as examples of patented solutions. As it is necessary to know the velocity of the passenger at the beginning of braking, the paper gives a basis for determining the kinematic parameters of the passenger. The analysis of kinematic parameters consists of two parts - the first one, which includes static analysis based on catenary theory, and the second, which takes into account inertial forces, movement resistance, air resistance, the position of a passenger during lowering, tightening force, etc. Finally, recommendations for the selection of zipline arresting system are given, as well as an example of concrete zipline which was built on Fruška Gora.
