The invention relates to a passenger conveyor comprising steps/pallets which are mounted to an endless drive member running between an upper conveying path and a lower return path, characterized in that at least one heating element is provided in the step/pallet, which heating element is connected to a power source. This solution prevents the building of ice surfaces on the steps/pallets of outdoor passenger conveyors.
