ABSTRACT:
In a hydraulic machine, a stay ring is provided with an upper bearing and an intermediate bearing so that an upper spindle of a guide vane is supported thereon. A bottom ring is provided with a lower bearing so that a lower spindle of the guide vane is supported thereon. The hydraulic machine is designed so that a runner and the guide vane can be removed from the bottom side if the bottom ring and an upper draft tube are removed. The guide vane is supported on the stay ring so as to make a head cover compact and to be capable of lifting the head cover through an upper pit liner if the head cover is formed as an integral structure.
