Abstract
A lifting fixture assembly adapted for shipping and/or lifting includes a lower turbine casing having two horizontal joint flanges adapted to engage mating flanges on an upper-turbine casing. The horizontal joint flanges are provided with plural bolt holes used for securing the upper turbine casing to the lower turbine casing. A plurality of cross-beams extend transversely across the lower turbine casing, removably secured to said horizontal joint flanges, using selected ones of the existing bolt holes.
Claims20
A lifting fixture and lower turbine casing assembly adapted for shipping and/or lifting the lower turbine casing comprising:
- a lower turbine casing having two horizontal joint flanges adapted to engage mating flanges on an upper- turbine casing, said horizontal joint flanges provided with plural bolt holes used for securing the upper turbine casing to said lower turbine casing;
- and
- a plurality of cross-beams extending transversely across the lower turbine casing, removably secured to said horizontal joint flanges, using selected ones of said plural bolt holes.
A lifting fixture and lower turbine casing assembly adapted for lifting and/or shipping the lower turbine casing substantially fully assembled except for a turbine rotor, the lower turbine casing formed with horizontal joint flange extending along opposite sides thereof;
- said horizontal joint flanges formed with plural bolt holes for bolting the lower turbine casing to an upper turbine casing;
- the assembly comprising:
- a first plurality of I-beams extending across said lower turbine casing and fastened to said lower turbine casing by bolts extending through selected ones of said plural bolt holes in said horizontal joint flanges, each of said I-beams comprising a web and flanges at opposite ends of said web;
- and
- a second plurality of outer, generally axially-oriented I-beams attached to each of said first plurality of I-beams and located along said horizontal joint flanges.
A lifting fixture and lower turbine casing assembly adapted for shipping and/or lifting the lower turbine casing comprising:
- a lower turbine casing having two horizontal joint flanges adapted to engage one or more mating flanges on an upper-turbine casing, said horizontal joint flanges provided with plural bolt holes used for securing the upper turbine casing to said lower turbine casing;
- a plurality of cross-beams extending transversely across the lower turbine casing, removably secured to said two horizontal joint flanges, using certain of said plural bolt holes;
- outer beams extending along said horizontal joint flanges generally in an axial direction and secured to each of said plurality of cross-beams;
- and
- at least one axially-extending beam between said outer beams and secured to each of said cross-beams.
