ABSTRACT:
The guide rail for a moving handrail on an escalator or moving walkway is mounted on a glass balustrade by a mount assembly which includes a vibration-isolating gasket between the balustrade and the guide rail. The gasket is preferably formed from a closed cell foam material which isolates vibrations so that vibrations of the guide rail and handrail engendered by operation of the handrail do not cause the glass balustrade to vibrate. Controlling vibration of the glass balustrade quiets the escalator since the glass, if allowed to vibrate, will act as a loudspeaker which magnifies and broadcasts escalator handrail noise.
