О критериях и нормах браковки канатов пассажирских канатных дорог

Abstract

The criteria for the rejection of ropes of Passenger cable cars are considered, the main defects of load-bearing, traction and load-bearing cables, possible causes of their occurrence and the criteria for rejection are described. The theoretical substantiation of defects associated with plastic deformations of the rope wire (extrusion of wires, stratification, twisting of the rope, kinks, breaks, basket shape) is given. The methods of monitoring the state of ropes in the process of operation of passenger cable cars are considered. Recommendations are given to improve the level of security by using remote monitoring systems based on modern digital information technologies. The criteria for rejecting the ropes of passenger cable cars are proposed: according to the undulation, wear and breakage of the outer wires of the ropes, which are absent in the current Federal Norms and rules «Rules for the safety of passenger cable cars and funiculars».
