Abstract: To solve the freight ropeway path planning in the mountainous region, we proposed a comprehensive method of construction site selection and path planning of freight ropeway. The calculation and analysis methods were studied to process the geographic information data, select the loading and unloading position, screen and optimize the trestle position, and estimate construction quantity. The ropeway cost analysis formula was proposed based on the main influencing factors of ropeway construction, which provides a basis for ropeway path sequencing and analysis. The ropeway paths of three iron towers in typical areas were planned, and 110, 17, and 32 ropeway paths that meet the requirements were obtained, respectively. The average calculation time was 2.34 h, much lower than the 1-2 days of the manual path planning method. It can be seen that the proposed method can effectively shorten the path-planning cycle of material transportation.
