The invention in its broadest form includes a device for inverting a cover with a predetermined weight from a horizontal position to an inverted position, the device comprising a crane for lifting the cover; at least two pivotable brackets each attached to both the cover and the crane and positioned to suspend a substantial amount of the weight of the cover for pivoting the cover; and a cable attached to the cover at one end and to the crane at its other end and positioned to suspend a nominal amount of the weight of the cover for supporting the cover.

Method and device for inverting a turbine cylinder cover

An improved method and apparatus for changing alignment shims used in conventional three-key bearing support systems for steam turbine rotors is provided by coupling the two lower bearing support pads together to maintain their fixed relationship relative to the spherical bore within which they are mounted.

Method and apparatus for aligning turbine rotors

A boring bar assembly for boring large diameter turbine bores in the field, the assembly utilizing a small hydraulic motor which drives a boring bar through an in line double reduction gear drive with a reduction ratio in excess of 100:1 and an output shaft which compensates for as much as 6.degree. angular misalignment between the boring bar and the output shaft of the gear box.

Boring bar assembly

A system for lifting a turbine disc having a mounting flange or balance ring, the system comprising a fixture having a base which attaches to the flange or balance ring, in elongated portion which extends beyond the periphery of the disc and a cantilevered portion extending from the distal end of the elongated portion and over the tips of the blades, eyelets disposed on the cantilevered portion and on the lower portion of the disc. The eyelets on the cantilever portion are disposed over the center of gravity of the assembly and a pair of hoists attached to the eyelets to lift the disc and move it to any orientation without damaging the blades.

Lifting system for a turbine disc

A fixture for supporting a sleeve and induction coil which encircles the sleeve to facilitate removal and replacement of shrunk-on sleeves on a shaft, the fixture having upper and lower portions electrically insulated from each other and standoff insulated studs and pads which support the sleeve and induction coil within the fixture to minimize circulating currents in the fixture and heating of the fixture.

Fixture for removing and replacing shrunk-on sleeves on a shaft

A method for removing and replacing shrunk-on sleeves on a shaft utilizing a fixture having upper and lower portions electrically insulated from each other and stand off insulated studs and pads which support the sleeve and induction coil within the fixture, the fixture having insulated parts which minimize circulating currents in the fixture that would result in heating of the fixture.
