Abstract

PURPOSE: To ensure the grasping of the stretching state of the footstep chain by means of a scale provided for a part of the driven gear to clearly indicate the movement of the gear.
CONSTITUTION: A bearing section 14 is provided with a scale on which gradations are arranged corresponding to the lift of the escalator. In response to the change in the gradation, the movement of the drive gear, namely the secular stretch of the footstep chain is indicated with a bracket 19 fixed to the frame side. The scale 18 is marked beforehand with degrees indicating the position of critical use corresponding to the number of unit of footstep chains used and the position of critical movement of the drive gear to check the colision with other equipments, or the like. In this manner, the stretching state of the chain can be learned immediately by reading the scale 18 in the maintenance of the escalator.
