Determination of tension forces of ropes during the operation of mobile transport and reloading rope complexes

During the operation of aerial ropeways, the system of carrying and carrying-traction ropes, which provides the possibility of moving passengers or transported goods between the terminal points of the route, experiences a high level of loading from a variety of operational loads and environmental influences. These loads and influences form the tension of the ropeway system variable along the length of the ropeway route, which has a decisive impact on the main technical and economic indicators of mobile ropeways, and thereby determines specific areas of their effective and inappropriate or unacceptable use. This article presents an engineering technique for constructing tension diagrams of carrying-traction ropes in stationary and non-stationary modes of operation of a mobile ropeway. Calculated dependences are given to determine the tension forces of ropes at characteristic points along their length, as well as calculated dependences for determining the resistance forces to the movement of ropes on characteristic sections of the mobile ropeway route. This technique can be used both for calculating the loading of the rope system based on taking into account a large number of factors characterizing operational loads, terrain parameters and transported cargo, and for analyzing the direction and significance of the variation of these factors and the main design parameters of the main technological equipment of mobile transport and reloading rope complexes. The results of the analysis of the influence of the variation of a number of significant quantitative parameters on the change in the tension forces of the carrying-traction ropes are also presented.
