MONITORING A SUPPORTING AND PROPULSION MEANS OF AN ELEVATOR SYSTEM

摘要

The invention relates to a monitoring device (200) for a supporting and propulsion means (3) of an elevator system (100). The supporting and propulsion means (3) comprises at least one electrically conductive cord (21), and the monitoring device comprises a measurement device (25) for determining a resulting resistance. The measurement device (25) is connected to the supporting and propulsion means (3) by means of contacting elements (20), wherein a first contacting element for contacting a first end of the supporting and propulsion means (3) and a second contacting element for contacting a second end of the supporting and propulsion means (3) are provided. In one embodiment, a damage of the supporting and propulsion means (3) is detected by a contact point (P) which can detect protruding conductive parts of the supporting and propulsion means (3) and, in a further supplementary or alternative embodiment, the first and second contacting elements (20) respectively comprise several differing resistance elements (R) so that each cord (21) of the supporting and propulsion means (3) is connected to the monitoring device by means of two associated resistance elements (R).
