Abstract: With the gradual deepening of power grid construction, the main architecture of the power grid has been further strengthened and extended. Construction in high-altitude mountains and mountainous areas is increasing. Due to its high efficiency, low energy consumption, and environmental protection advantages, the cargo ropeway has been widely used in complex terrain power construction projects, especially in high-altitude mountain areas. However, in traditional cargo ropeway construction, the transit of materials is a difficult problem that restricts the improvement of transportation efficiency and safety levels. It relies heavily on manual disassembly, assembly, and transportation of materials between two-level ropeways, which severely affects transportation efficiency. In this context, the standardized heavy-duty ropeway bridge technology emerges.
