ABSTRACT:
The present invention teaches a mechanical device that monitors the support wheels, or rollers, of a moving escalator stair step. The diameter of each support wheel is indirectly measured by determining the height of each support wheel axial above a given plane. Support wheels that have unacceptable diameter trip an activation mechanism that sends an electrical signal to stop the escalator's driving motor.
