There is provided a method of installing spiral hangers about a messenger line installed between first and second utility poles with a cable being lashed to the messenger line with a lashing wire. The method includes attaching a first and second spiral hangers to the messenger line between first and second utility poles with the first spiral hanger disposed about the messenger line and the cable. The method includes removing the lashing wire from being around the messenger line and the cable adjacent the second spiral hanger. The method includes moving the second spiral hanger towards the second utility pole. The method includes attaching a successive spiral hanger to the messenger line between the spiral hangers, and repeating the moving of the second spiral hanger and attaching another successive spiral hanger.

The embodiments provide a transformable robot mechanism and an inspection robot. The robot mechanism includes a functional device box, balance side shells, a battery cell, and a control panel. The balance side shells are rotatably installed on two sides of the functional device box respectively, wherein the balance side shells on one side of the functional device box are internally provided with the battery cell, and the balance side shells on the other side of the functional device box are internally provided with the control panel.
