Staircase with step brushes, stage of such a step and procedures for modernising a step

摘要

The escalator has a tread surface (6) and a riser surface with riser brushes (3), where the brushes are arranged on a step at the riser surface in an approximately parallel direction. The brushes are inserted at riser edges or over an entire area of a riser and along an entire riser region. The brushes are mounted to a brush strip which is guided along the riser as a step transfer between vertical and horizontal travels.
