Replacing the stator generator of unit A3 with the use of specialized construction without the use of a crane, by means of hydraulic systems for horizontal and vertical transport

Generator weight: 305 tons

The scope of work included:
- technologies of conducting works,
- design and delivery of supporting and auxiliary structures necessary for
carrying out the task,
- dismantling the old generator stator, including:
1. Lifting the stator with its housing from the foundation,
2. Disassembly of the housing,
3. Lifting and horizontal transport of the stator beyond the engine room building,
4. Lowering the stator from + 9, Om to pos. of Om,
5. Rotation of the stator O 90st and horizontal transport instead of storage distant by 230m.
- assembly of a new generator stator, including:
1. Unloading of the stator delivered to the power plant area from a specialized railway wagon (NORCA 24)
2. Horizontal transport (about 230m) of a new stator from the place of unloading to the place of lifting in front of the machine room building,
3. Rotation of the stator O 90st,
4. Lifting the stator from O, Om above the level of + 9, Om by means of hydraulic lifting systems,
5. Horizontal transport of a raised station
