What does the annual testing of the governor involve regarding its parts?

The annual testing of the governor is crucial for ensuring the safety and functionality of the elevator system. It involves operating all parts manually for free movement. This process is essential because it allows maintenance personnel to verify that the governor, which is a critical safety component, operates correctly under various conditions. By manually engaging and releasing its mechanisms, technicians can identify any potential issues, such as sticking or binding parts, that could impair the governor's performance in an emergency situation.

This hands-on testing helps ensure that the governor can effectively regulate the speed and behavior of the elevator, particularly in scenarios where rapid stopping is necessary to prevent accidents. Regular operational checks contribute to both safety and compliance with regulatory standards, making this method a fundamental part of maintenance practices.
