Abstract： In order to solve the problem that the metal structure of converting and rotating devices have large deformation and the center of gyration is hard to position，founded on the Zhexi Hydroelectricity station dam passing slide device rebuilding project，the track rotating device in the railway and mine was briefly analyzed，the gyration support mechanism was used on the track rotating device of Zhexi Hydroelectricity station dam passing slide device successfully. Aiming at the metal structure mechanical property of the track rotating devices when the devices were working，the basic assumptions were proposed，the results of stress and defection curve of new and old devices was gotten from the static structure analysis in strength and stiffness. Finally，according to the basic assumption and the site installation situation，the basic principle of gyration support installation was proposed to make sure metal structure of the rotating device working conform to the mechanic model of new devices. The results and the site operation detection both indicate that the gyration devices improve the track strength and stiffness significantly.
