Reliance Infrastructure ltd., one of the biggest EPC companies in India was setting up a 2x600MW Thermal power plant for Haryana Power Generation Corporation Limited in Hissar, Haryana. The power plant equipment including the Generator was supplied by Shanghai Electric Company, China. The 10.5m long Generator weighing 320MT was to be installed at a height of 13.7m
The Stator had to be lifted from the ground level outside A row to the TG deck height of 13.7m. Lifting with a crane was ruled out as the TG deck was covered with a permanent roof since electric equipment like Generator can not be exposed to weather elements. The other problem was the clearance between columns A4 and A5 which was less than the length of the Generator. Also, the clearance of only 9.7m between the TG deck and the bottom of the EOT girder posed a big challenge since the lifting gantry had to be designed within a height of 9.7m so that the lifting equipment slides below the EOT girder.
