Abstract:
An escalator handrail washing device according to one embodiment of the present invention comprises: a case that accommodates an escalator handrail and a washing unit; a self-generation unit, arranged in the case, for converting kinetic energy of the escalator handrail into electric energy; and a communication unit for transferring information on an operating state of the escalator handrail to a control center. The washing unit includes a plurality of rollers. At least one roller is rotated without power, by frictional force generated by contacting a surface of the escalator handrail, in a first direction which is a reverse direction of a preset rotating direction of the escalator handrail.
