When installing power transmission towers in mountainous areas and using large unmanned helicopters to drop steel structure components, there is no need to build roads, which can greatly shorten the erection period of line towers and save transportation costs. For transportation operation has developed a large mountain line tower unmanned helicopter transport system, the system is developed by Beihang university, 500 kg large flying unmanned helicopter as a platform, carrying over-the-horizon autonomous navigation module, wireless image transmission module, electromagnetic lifting on the module, a single flight can carry 200 kg payload into the transportation on the job, without human intervention, reduce mountain flight personnel risk. A successful flight operation was carried out in the mountainous area of Wenzhou, Zhejiang province in December 2019. The results show that the transportation cycle of the tower can be shortened from months to less than a week by using a large, unmanned helicopter to lift the steel structure components in the mountainous area, and the engineering cycle can be greatly shortened, and the transportation cost can be saved.
