发明名称 IMPROVED METHODS OF RAISING UTILITY POLE TRANSMISSION CABLES
摘要 A method of raising the transmission hardware carried by a utility pole having a base end with a ground foundation supporting the pole in upright position, without disturbing the pole foundation or disconnecting the cables, includes the steps of securing opposed, circumferentially spaced elongate pole support members to extend upwardly along the pale and severing the pale to define a first pale supported by the pole foundation and a second pole supported by the first pole; fixing the support members to the first pole and slidably banding them to the second pale; raising the second pole above the first pole to a level remaining below the upper ends of the support members; and fixing the lower end of the second pale within and to the upper ends of the support members at a spaced distance above the first pole. The method further contemplates the releasable securement of ladder steps to at least one of the support members to provide ready access for carrying out some of the method steps.
