TECHNICAL REASONS FOR WIRE BREAKS OF CARRIER-TRACTION ROPES ON PASSENGER CABLEWAY

The article presents the examination results in order to establish technical reasons for wire breaks of the carrier-traction rope on the passenger cableway. It was established that the main causes of breakage of wires were: a defect in the form of undulations, arising from the unequal distribution of tensile load be-tween the rope strands. Corrosion on the defective area indicates on the improper interaction between the strand ropes in undulation area, and the squeezingof the inner ribbon and the core all over the splice. The carried out examination has identified that the dam-age of carrier-traction rope strands is a con-sequence of improper use of cable cars, with regard to the failure to conduct carrier-traction rope audit, and notperforming the periodic application ofspecial lubricants on the whole rope and on the splice. Repair of the above mentioned carrier-traction rope can be done by replacing the defective strand or by replacing the defective part by the qualified technology manufacturer.
