[0002] UHV transmission line projects can transmit electricity over long distances and have a wide regional span. As land resources become increasingly scarce, more and more transmission line project design routes need to pass through mountainous terrain with poor transportation conditions, which brings great difficulties to project construction and material transportation. One of the effective ways to solve the material transportation problem in mountainous terrain for UHV transmission line projects is to use cableways for material transportation. Cableway transportation can significantly reduce the construction of temporary construction roads and has little impact on the environment around the line.

[0003] There are many transmission line construction projects in mountainous areas. Affected by construction costs and environmental protection requirements, tower materials, concrete and other materials are generally transported by cableway. Some tower foundation construction sites have large working areas, and there is still a long distance between the cableway unloading point and the construction site. In addition, according to environmental protection requirements, the excess stones excavated from the foundation need to be transported out for processing. If manual transportation is used, it will cause a significant waste of resources.
