Abstract
The article presents the basic technical requirements for carrying-hauling ropes for monocable aerial ropeways contained in the Directive 2000/9/EC of the New Approach of March 20th 2000 on cableway installations designed to carry passengers and in European Standards harmonized with it. These requirements apply to materials used for ropes, methods of manufacturing of wires and ropes, physical parameters, mechanical properties, testing methods and rope discarding criteria. The article summarizes the different types of loads in carrying-hauling ropes for monocable aerial ropeways and their impact on the operation of the cableways. It also touches the subject of the properties of carrying-hauling rope constructions with equal lay and compacted strands used in ropeways in Poland in the last two decades with particular emphasis on the structure of cores made of plastics. An analysis and assessment of the rope operation has been carried out in the last part of the article. This analysis considers factors such as the rope construction, the method of carriers gripping, lay direction of rope related to the direction of ropeway movement, rope elongation depending on the type of core and the associated rope shortening and rope fatigue life.
