Expert: Elevators have a self-protection mode. When the voltage is unstable or there is a problem with the door lock system, it only slows down or protects the car and stops. When it is checked that there is no major problem with the elevator, it continues to run to the same level, which is called elevator stall. Because during the normal operation of the elevator, we do not feel any obvious movement, which is why there is a feeling of "falling" when braking. Just like driving, when the driver steps on the brake, there is such a sudden sensation. You can't see this movement inside the elevator car, so the feeling of "falling" will be more pronounced.

If the elevator really falls, it is a free fall. If it falls into the foundation pit with a bang and cannot be salvaged, it will fall into the elevator accessory buffer. But this situation is extremely rare, almost non-existent. If it's a fall, at least the lower floors will break, and the people on the higher floors will be beyond rescue. It won't just be skin injuries like abrasions and bruises.
