What is the purpose of a safety brake in an elevator?

The purpose of a safety brake in an elevator is to halt the elevator car if it begins to descend at an unsafe speed. Safety brakes are critical safety devices designed to operate under emergency conditions; if the elevator's speed exceeds a predetermined limit, the safety brake activates, bringing the car to a stop. This mechanism is essential for protecting passengers and preventing accidents, ensuring that the elevator operates within safe parameters.

While other components of the elevator system may contribute to its overall performance or comfort, the specific function of the safety brake is to provide a safety response to excessive speed, thereby safeguarding against potential falls and serious injuries. This direct link between speed control and safety is vital in elevator design and operation.
