1. An electric generator phase ring handling tool, comprising: a base unit configured to move in a fore and aft direction, wherein the base unit includes a front-end part, a back-end part and a vertical extending part between the front-end part and the back-end part;
a vertical support structure coupled to the base unit, wherein the vertical support structure is configured to tilt towards and away from the vertical extending part;
a phase ring support head coupled to the vertical support structure, wherein the phase ring support head is configured to rotate and move along the vertical extending part of the base unit;
at least three support arms coupled to the phase ring support head, wherein said at least three support arms are configured to support one or more electric generator phase rings; and
wherein the vertical extending part is coupled to the vertical support structure with a first drive system, wherein the first drive system is configured to tilt the vertical support structure towards and away from the vertical extending part of the base unit, and the first drive system is a screw drive system comprising a screw and a hand wheel configured to drive the screw.
