Patent ID: 8686747

Claim:
A monitoring device for a suspension-and-traction means of an elevator system, which suspension-and-traction means contains at least one cord that is electrically conductive, comprising: a measurement apparatus for determining a resulting electrical resistance, and first and second contacting elements electrically connecting the measurement apparatus to the at least one cord of the suspension-and-traction means, wherein the first contacting element contacts a first end of the at least one cord, and the second contacting element contacts a second end of the at least one cord; and a resistor electrically connected to the measurement apparatus and to a contact point over which the suspension-and-traction means runs so that the monitoring device detects a contact of the contact point with the at least one cord of the suspension-and-traction means, and wherein the first and the second contacting elements each contain at least one resistor, so that the at least one cord of the suspension-and-traction means is electrically connected via the resistors of the contact elements to the measurement apparatus.
