Structure allowable natural frecuency

[LQQD]

Hi all!, I am designing an industrial platform wich supports a hoist, see attached image. As the columns supoprting de runways are quite long I am concerned with the vibration of the structure. Does anyone have some recomendation or reference of what minimum natural frecuency should the structure have? Couldn't find anathing on CMMA 74

thanks!

I'm not sure that there is one. Typically with crane/hoist runways, if you satisfy the deflection criteria (with a impact factor).....you are ok with any kind of vibration.
