After the arrangement of the box girder supporting the stator is completed, use a level to uniformly measure and adjust the upper surface to the same elevation, and after the bottom is adjusted and cushioned with a suitable thickness of steel plate, the 630T crawler crane lifts the stator again. At this time, the lifting radius of the stator is 14m , 54m main boom + 15m super lift radius super lift condition. When the bottom of the stator is 100mm away from the crawler pad, the crane stops lifting the hook. Check the stator hoisting rigging and various parts of the crawler crane, and the overlifting counterweight leaves the ground. After confirming that there is no abnormality, the 630T crawler crane continues to hook until the height of the stator bottom exceeds The crane stops hooking when the upper surface of the hydraulic lifting device track is 100mm on the basis of the generator. On both sides of the stator, rotate the stator 90° clockwise slowly with a drag chain hoist that has been hung in advance, and stop rotating when the longitudinal centerline of the stator coincides with the longitudinal centerline of the generator. After the stator is stable, the operating radius of the 630t crawler crane is 14m. When the height of the bottom of the stator from the upper surface of the box girder is 100mm, the crawler crane starts to move forward slowly until the center of gravity of the stator coincides with the design center of gravity when laying the box girder. When the generator's official center of gravity is 3997mm), stop the car and slowly return to the hook to steadily drop the stator on the 7 box beams. Then it was confirmed that the 7 support box beams were in close contact with the generator table surface, and the table and the temporary support horns at the bottom were in close contact, and there was no abnormality, the 630T crawler crane was unhooked and the super-lifting counterweight was removed.

After the arrangement of the support steth with box beam is completed, the level measurement is adjusted to its upper surface height consistent, and the bottom of the mat is adjusted with the appropriate thickness steel plate, the 630T track crane lifts the stator again, at this time the lifting stator operating radius is 14m, 54m main arm and 15m over-lifting radius over-starting conditions. When the bottom of the stopper leaves the track pad 100mm when the crane stops hooking, check the stopper lifting rope and track lifting parts, and the over lifting weight leaves the ground, confirm that there is no abnormality, the 630T track lifting continues to hook, to the bottom height of the stationer exceeds 100mm on the surface of the hydraulic lifting device track when the crane stops hooking. The two sides of the sage will slowly rotate the stopper clockwise by 90 degrees with the pre-hung drag hand hoist, stop the rotation when the longitudinal centerline of the stopper and the vertical centerline of the generator meet, the radius of the 630t track lifting operation remains unchanged after the seth is stable, the 630T track crane will begin to slowly hook back to the bottom of the stationer when the surface height of the box beam is 100mm, stop the slow hook, and the track will start to move slowly forward. Stop the vehicle when the stopper center of gravity point and the design center of gravity position when laying the box beam (3997mm from the official center of gravity point of the generator), and slowly hook back to smooth the stopper on the 7 box beams. Then confirm that 7 support box beams and generator bench surface contact strict, table plate and its bottom temporary support pad iron contact strict, and there are no abnormal, 630T track lifting hook, remove the super lifting weight part.

After the layout of the box girder supporting the stator is completed, the level is used to measure and adjust it to the same elevation of the upper surface, and the bottom is adjusted and padded with steel plate of appropriate thickness, the 630t crawler crane will lift the stator again. At this time, the operation radius of lifting the stator is 14m, and the 54m main arm + 15m super lift radius is super lift condition. When the bottom of the stator is 100 mm away from the track pad, the crane stops hook lifting. Check the stator lifting rigging and all parts of the crawler crane, and the super lifting counterweight is off the ground. After confirming that there is no abnormality, the 630t crawler crane continues to hook until the bottom of the stator is 100 mm higher than the upper surface of the hydraulic lifting device rail on the generator foundation. On both sides of the stator, slowly rotate the stator clockwise by 90 ° with the tug chain block hung in advance until the longitudinal center line of the stator coincides with the longitudinal center line of the generator. When the stator is stable, the working radius of 630t crawler crane remains unchanged at 14m. The 630t crawler crane starts to hook back slowly. When the height between the bottom of the stator and the upper surface of the box girder is 100 mm, the slow hook stops, and the crawler crane starts to move forward slowly When the center of gravity of the stator coincides with the designed center of gravity when laying the box girder (3997mm away from the formal center of gravity of the generator), stop walking and slowly return the hook to make the stator fall on the seven box girders smoothly. After confirming that the seven support box girders are in close contact with the generator platform surface, and the platform plate is in close contact with the temporary support pad iron at the bottom, and there is no abnormality, the 630t crawler crane takes off the hook and removes the super lifting counterweight part.
