The invention relates to an overhead line erecting method in the field of high-voltage power transmission. The method comprises the following steps: S1, placing a yoke plate and a block together at the lower end of an insulator string; S2, making bundled conductors cross the block and placing the bundled conductors on the pulleys of the block; S3, hoisting the bundled conductors one by one to corresponding positions of the yoke plate through lever hoists; and S4, removing the block. The problem in the existing line erecting method that the number of lever hoists required is large and the block is inconvenient to remove is solved.
