Force calculation of the fastening mechanism of the end tower of a mobile transport and reloading rope unit using a holding rope

Mobile transport and reloading rope units based on special self-propelled wheeled chassis with increased load capacity and cross-country capability are currently a promising type of rope transport technologies for logistics operations in difficult natural conditions, if necessary, their rapid deployment. However, the issues of designing and analyzing the work processes occurring in the main technological equipment of these units during the operation of single-span mobile ropeways of the pendulum type have not yet been sufficiently investigated. This article presents a mathematical model designed to perform a force calculation of the mechanism of rope fixation of the end tower during the opera-tion of a mobile transport and reloading rope unit. The model makes it possible to determine the magnitude of the force in the holding rope and the support reactions in the attachment points of the end tower and the rope winch, depending on the design dimensions of the mechanism and the tower, the operational load from the carrying-traction rope system of the mobile ropeway, the spatial orientation of the rope pulley and other parameters. The analysis of the obtained quantitative results of the test force calculation of the rope fixation mechanism of the end tower is also presented and appropriate recommendations are formulated.
