Which components are involved in an elevator's safety system?

The safety system of an elevator is critical for ensuring safe operation and protecting passengers during use. The correct answer encompasses a comprehensive range of components that work together to prevent accidents and ensure safe functioning.

Overspeed governors are essential devices that monitor the speed of the elevator car. If the car exceeds a predetermined speed, the governor activates the safety system to apply the brakes, preventing the car from falling or moving too quickly.

Emergency brakes are vital for stopping the elevator car in the event of a malfunction. They engage automatically or can be activated by the operator, providing a fail-safe against system failures.

Buffers serve as shock absorbers at the bottom of the elevator shaft. They cushion the elevator car in case of an emergency landing or if the car descends too rapidly, helping minimize the impact and protecting both the car and its occupants.

Door interlocks ensure that the elevator doors close securely before the elevator can move. This prevents doors from opening while the car is in motion, further protecting passengers from accidents.

This combination of components makes the safety system robust and reliable, addressing various potential hazards that can occur during elevator operation. Other options may include some safety components, but they do not encompass the full range necessary to describe a comprehensive elevator safety system.
