Abstract: An elevator car guide wheel system includes a guide wheel located at an elevator car, configured to contact a guide rail of an elevator system. The guide wheel includes a wheel hub located at a guide wheel axis, a wheel rim, and a wheel outer portion located at the wheel rim and configured for contact with the guide rail. A magnetic element is located at the guide wheel, and a sensor is located at the guide wheel and is configured to detect rotational direction and rotational speed of the guide wheel about a guide wheel axis via detecting a magnetic field of the magnetic element.

Abstract: Disclosed is an escalator system wherein when a handrail belt is moving from rotation of a plurality of elevator sheaves: a controller receives data from a plurality of sensors, identifies from the data a first sheave of the plurality of sheaves as comprising reference alignment value for the system, determines for the plurality of sheaves a respective plurality of alignment values, compares the plurality of alignment values with the reference alignment value, and provides a predetermined response when any of the plurality of alignment values diverges from the reference alignment value by more than a predetermined amount.
