Which component regulates the elevator's movement speed during heavy loads?

The governor is a critical component in an elevator system that plays a key role in regulating the movement speed, especially when the elevator is handling heavy loads. It functions as a safety device that monitors the speed of the elevator car and ensures that it does not exceed predetermined limits. In situations where the elevator is carrying a heavy load, the governor can detect if the system is moving too quickly and will activate safety mechanisms to slow down or stop the elevator, thereby preventing accidents.

Governors are typically connected to the elevator's cab and the hoisting mechanism, providing real-time feedback on speed. This ensures that even under varying load conditions, the elevator can maintain safe and efficient operation. Moreover, while the controller manages the overall operation of the elevator system, it is the governor that specifically addresses speed regulation, making it essential for safe operation during heavy loading scenarios.
