A method of mounting a natural draft cooling tower having a tower mantle suspended on a central support projecting beyond the upper rim of the mantle which is clamped and tightened between a pressure ring at the upper rim of the mantle and a foundation. In order to mount the cooling tower mantle, the pressure ring lying on the ground and coaxially surrounding the central support is suspended on a lifting ring by means of a plurality of supporting cables exceeding in length the radius of the pressure ring. This lifting ring is guided on the central support, suspended on a plurality of pulling elements which are lifted by at least one lifting device detachably connected to the central support, as a mantle section corresponding to the advance of the lifting device is displayed. After the lower rim of the cooling tower mantle has been connected to the foundation, the mantle is tightened by the lifting device. By attaching the lifting ring to the central support, the cooling tower mantle is maintained in its pre-stressed position. |
