Abstract: In order to study the structural mechanical performance of freight ropeway under the influence of dynamic factors, the calculation method of ropeway dynamic structure is adopted. According to the typical construction conditions and main technical parameters of freight ropeway, the calculation conditions of ropeway start-up under different parameters are designed according to the transportation start-up factors affecting the safety performance of ropeway. By comparing the cable load, start-up speed, start-up position, height difference change and span change of the cableway, this paper makes a quantitative analysis on the influence of the cableway start-up power, and puts forward the load coefficient of the start-up factors on the structure calculation of the towing cable and the towing device, so as to provide more scientific and reasonable reference for the design of the freight cableway.
