Abstract:
1. A method for testing at least one carrier element of an elevator installation in which the carrier element carries an elevator car, wherein the carrier element is a sheathed carrier element, comprising the following steps: activating a transmission unit ‘for emitting electromagnetic’ radiation directed at the carrier element; activating a reception unit for receiving the electromagnetic radiation to generate test data representing a current state of the carrier element from the received electromagnetic radiation; evaluating the test data in a calculation unit to determine a deviation of the test data from reference data representing an intended state of the carrier element, wherein the reception unit is responsive to electromagnetic radiation with a wavelength in a range of between 90 μm and 120 μm; generating from the calculation unit an output signal representing the determined deviation to at least one of present a visual display and control a drive unit driving the carrier element of the elevator installation; and including at least one of:
