What is the primary safety function of the governor in an elevator system?

The governor's primary safety function in an elevator system is to detect overspeed conditions and activate safety devices. This component is crucial for maintaining safety during an elevator's operation. By continuously monitoring the speed of the elevator, the governor can sense if the elevator is moving faster than its safe operational limits. If an overspeed condition is detected, the governor triggers safety mechanisms, such as the brake system, to bring the elevator to a stop and prevent potential accidents or failures.

This function is vital because overspeed can lead to dangerous situations, including elevator cars falling or failing to stop properly at designated floors. Therefore, the governor serves as a critical safety backup that ensures the elevator operates within its design parameters. Its role is aimed at protecting the passengers and the equipment, making it essential for elevator safety protocols.
