[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line; during the use of the elevator, there is generally a rated bearing capacity. Once the weight inside the elevator exceeds the rated bearing capacity, the elevator will stop running and malfunction. The counterweight sheaves and steel wire ropes of the elevator car are important components for elevator load-bearing. The phenomena such as breakage and unhooking of the counterweight sheaves and steel wire ropes of the elevator car often occur during the use of the elevator, causing certain losses and social impacts, and exposing relatively large safety hazards. Therefore, the stability of the counterweight sheaves and steel wire ropes of the elevator car needs to be guaranteed to eliminate such safety hazards. Content of the Utility Model
