The invention discloses whole set of technology to install attachments in power transmission line construction by using a strain type scaling ladder. The main technology characteristic is that hard replaces soft. The upper end of a scaling ladder (2) is provided with a movable ring (11), (5)s are configured to change various angles and positions, and (6)s position to ensure operation safety. Using the above scheme can make (9)s in various models achieve optimal technology according to design requirement. The scaling ladder is necessary to popularize.
