The safety system of an elevator mainly includes the following key components: overspeed governor/safety system, buffer system, door lock system (door safety system), emergency braking device, and safety protection functions in the electrical control. Here is a detailed description of these systems

**Overspeed Governor/Safety Gear System**:
The overspeed governor is responsible for monitoring the elevator's speed in real time. the elevator speed exceeds the set safety threshold, the overspeed governor triggers the safety gear to safely decelerate or the elevator.

- **Buffer System**:
The buffer is typically located at the bottom of the elevator shaft and is used to absorb the impact force in of an uncontrolled elevator fall. It effectively reduces the risk of passenger injuries and serves as the final line of defense in the safety system.

- **Door Protection System (Door Safety System)**:
The door safety system ensures that the elevator doors do not open abnormal conditions through multiple protections. This includes door locks, anti-pinch devices, etc., to ensure passenger safety during the elevator door and closing process.

- **Emergency Braking Device**:
The emergency braking device acts as the "emergency brake" of the elevator and can quickly brake the in case of an emergency. It achieves instant stopping of the elevator's operation through precise mechanical devices, protecting the passengers' lives.

-Safety Protection Functions in the Electrical Control System**:
The electrical control system is responsible for processing various information of the elevator ensuring that the elevator operates according to established procedures. It includes various safety protection functions such as power failure protection, overload protection,., to ensure the elevator's safety in abnormal situations.

Additionally, the elevator's system may also include overload protection systems and emergency alarm systems to further passenger safety. These systems together form multiple safety barriers of the elevator, ensuring the safety of the elevator under normal operation and abnormal conditions.
