Identify one common safety device used in elevators.

Safety brakes play a crucial role in the overall safety mechanism of elevators. They are designed to stop the elevator car from falling in the event of a cable failure or other malfunction. This device engages automatically if the elevator starts to move too quickly due to an overload or malfunction, ensuring that the car decelerates and comes to a complete stop safely.

The implementation of safety brakes is essential in building confidence in the reliability of elevator systems. They contribute to the overall safety standards that elevators are required to meet, helping to protect passengers during transit. In the context of elevator safety devices, safety brakes are a fundamental component that enhances the reliability and safety of the entire system.
