If you notice roughing on the governor and tail sheave, what should you check?

  1. Oil level

  2. Rope diameter

  3. Voltage

  4. Control panel

The correct answer is: Rope diameter

The appropriate action when noticing roughing on the governor and tail sheave is to check the rope diameter. A roughing appearance can be indicative of a potential issue related to the cables or ropes used in the elevator system. The rope diameter is crucial because if the diameter is incorrect or if the ropes are worn, it can lead to improper seating on sheaves, resulting in wear and roughness on the components. Ensuring that the rope diameter is correct will help maintain the smooth operation of the system and prolong the lifespan of both the governor and the tail sheave. This check is vital, especially in systems where the correct tension and fit are critical for safety and functionality.
