The installation of the fan with a total weight of approximately 58 tonnes and a motor power of 3,060 kW on a flexible foundation that takes up the vibrations is the speciality of this case. The operation of machines is always attended by vibrations. The inherent rigidity of large fans, however, does not allow for a direct mounting on anti- vibration mounts, since this would not be sufficient for the vibration isolation to the environme
