The invention relates to an escalator component, in particular to an escalator handrail operating device, which comprises a handrail guide rail bracket and a handrail positioned on the handrail guide rail bracket. A turning chain is arranged in the handrail guide rail bracket and comprises a bracket connected nose to tail; the bracket is provided with an axial hole in which an idler wheel mounting shaft is arranged; the end part of the idler wheel mounting shaft in the axial hole is provided with a sliding bearing; the two ends of the idler wheel mounting shaft are sleeved with an idler wheel respectively; the two sides of the bracket are provided with a lug boss; and a distance between the free end of the lug boss and the inner end face of the handrail guide rail bracket is less than that between the end face of the idler wheel and the inner end face of the handrail guide rail bracket. The invention mainly provides the escalator handrail operating device, which has the advantages of low noise, lon service life of the handrail and smooth rotation; and the technical problems in the prior art that a handrail guide rail, with a rolling bearing turning chain, of an escalator easily produces noise and that a rolling bearing is partially heated after dust enters the rolling bearing and has short service life are resolved.
