METHOD AND CONTROL DEVICE SYSTEM FOR MONITORING THE SUSPENSION TRACTION MEANS OF AN ELEVATOR AND ELEVATOR SYSTEM COMPRISING AN ELEVATOR AND A CONTROL DEVICE SYSTEM

摘要

A method for monitoring the suspension traction means (10) of an elevator is disclosed, wherein the suspension traction means (10) comprises several cords (20-25), wherein the method comprises the following steps: measuring a thickness of at least one cord (20-25) of the suspension traction means (10) at at least one point of the cord (20-25); comparing the measured thickness of the cord (20-25) with a first value and/or with a second value, wherein the second value is lower than the first value; and generating and sending a warning signal when the measured thickness of the cord (20-25) at at least one point of the cord (20-25) is lower than the first value and/or generating and sending an operation terminating signal for terminating the operation of the elevator when the measured thickness of the cord (20-25) at at least one point of the cord (20-25) is lower than the second value.
