Abstract
A light console-type double-level rotating steel lifting pole was developed for tower erection under the special circumstance of the Zhejiang section of Xiangjiaba-Shanghai ±800 kV UHVDC transmission project,where the transmission corridor is narrow and the terrain condition is very poor,making it difficult to erect the towers.This construction technology is proved to be applicable to erection of angle-steel towers and steel-pipe towers of the UHV transmission lines,the towers in mountainous and hilly areas where guy installation is difficult,or the towers which are close to the live lines and guys cannot be installed.
