1. A rotor jacking system for a turbine or generator, comprising:
- a rotor rotatably disposed in a turbine or generator; and
a jacking assembly comprising;
an arc-shaped saddle configured to extend around and support a lower portion of the rotor without removing the rotor from the turbine or generator, the saddle having two blind holes formed therein;
a lifting beam configured to extend over the rotor transversely to an axial direction of the rotor, the lifting beam being axially aligned with the arc-shaped saddle; and
two connectors disposed on respective lateral sides of the rotor, each connector extending between and being attached respectively to the lifting beam and the arc-shaped saddle such that the arc-shaped saddle is positioned spaced-apart from the lifting beam, the connectors being received, respectively, in the two blind holes without passing through a rear side of the saddle,wherein one or both of the two connectors is configured to facilitate rotating the saddle around the rotor, while the rotor is disposed in the turbine or generator, until the saddle is positioned beneath the lower portion of the rotor, andwherein the saddle is configured to lift the rotor vertically when the lifting beam is displaced vertically.

Abstract
A jacking assembly for a rotor of a turbine includes an arc-shaped saddle which extends around and supports a lower portion of a rotor. A lifting beam extends over the rotor transversely to an axial direction of the rotor. The lifting beam is axially aligned with the arc-shaped saddle. Two connectors are disposed on respective lateral sides of the rotor, each connector extending between and being coupled to the lifting beam and the arc-shaped saddle such that the saddle is configured to lift the rotor vertically when the lifting beam is displaced vertically.
