Abstract
A lubricating device for an escalator or moving walkway provides a lubricant container connected by way of lines with lubrication points which are arranged at a base plate which forms lateral borders for the escalator/moving walkway step belt or plate belt. Sliding pads are provided at the escalator steps of the step belt or at the plates of the plate belt which project slightly beyond the side edges of the steps or plates and, when sliding past the lubrication points, receive lubricant and subsequently transfer it to the base plate.
