Rail system for installing a stator core in a frame

A rail system for use in installing a stator core in a generator frame, comprising:

• a plurality of rail assemblies for installation in the frame, wherein each rail assembly comprises;
• a plurality of support pieces positioned at a respective circumferential location along frame rings of the frame from an exciter end to a turbine end of the frame;
• a plurality of fasteners configured to secure the plurality of support pieces to the respective circumferential locations along the frame rings;
• a plurality of lifting assemblies positioned on the support pieces;
• a support beam segment positioned on each lifting assembly such that a support beam including a plurality of support beam segments extends axially along the plurality of support pieces of the rail assembly;
• and
• a rail segment positioned on each support beam segment such that a rail including a plurality of rail segments is axially positioned along the plurality of support pieces of the rail assembly.

A system for installing a stator core in a frame comprising:

• a rail system installed in the frame;
• a lifting assembly configured to adjust a height of the rail system such that stator core segments guided into the frame along the rail system are aligned to fit in the frame;
• and
• a plurality of keybars for securing the stator core segments to the frame;
• wherein the rail system is configured to be detached and removed from the frame once the stator core segments are secured to the frame.
