ABSTRACT:
An air supporting system is provided for a handrail of a passenger conveyor and includes a plenum. An air supply provides air flow to the plenum. A guide is mounted on one side thereof to the plenum. The guide includes at least one air pocket. A handrail is slidably engaged with the guide. An orifice through the guide allows air to pass from the enclosed space to the air pocket. The air in the pocket generates pressure and lift to the handrail as it is driven to decrease friction between the handrail and the guide and to support the handrail above the guide.
