Abstract
The UHV power transmission line from Huainan to Shanghai uses the steel tube tower for the first time,and the cross arm connection of the tower uses existing suspending arm pull rod construction technology which can't meet the tower cross arm hoisting requirements.Through the analysis of tower structure,we selected aiding 人 shape derrick and hoisting test.The research determined the new technology of the steel tube tower cross arm hoisting,which was applied in the engineering.
