What is the primary function of an elevator's governor?

The primary function of an elevator's governor is to monitor the speed of the elevator and initiate safety measures. The governor acts as a critical safety device in the elevator system, continuously measuring the speed of the elevator car as it travels. If the elevator exceeds a predetermined speed, which could indicate a potential malfunction or unsafe condition, the governor activates a safety mechanism, such as the braking system, to slow down or stop the elevator. This process is vital to ensure passenger safety and reliability in elevator operations. The governor's role is central to preventing accidents, maintaining control over the elevator's motion, and ensuring that the system operates within the safety parameters established by regulatory standards.
