Description
Summary:The article deals with the safety of labour and of technical equipment in timber skidding using forest cableways. It analyses the applicability of the current theory used for designing cableway routes from the point of view of safety in terms of an excessive overload. The analysis, which was carried out using situational models, has shown that the skyline will break as a result of several fold excess of the safe working load. The value of the buckling load is in such case at least 3.5 times higher than that of the safe working load. Our results have confirmed the applicability of the theory currently used in designing cableway routes.
