What if the elevator falls?
If passengers find the elevator "falling", please keep calm and don't panic, and wait for the elevator to stop running. If you are trapped in the elevator car, you can give an alarm to the personnel on duty of the user unit through the emergency alarm device according to the prompt in the car, call the emergency rescue phone of the elevator maintenance unit, or contact the 96333 emergency handling phone, and the maintenance rescuers will go to the rescue at the first time.

There are many kinds of safety devices in elevator design. For example, the steel wire rope for pulling the elevator car is composed of multiple steel wires, and generally, multiple steel wires will not break at the same time. In addition, the elevator is designed with a "speed limiter-safety clamp" linkage protection device. If the wire rope breaks or the elevator descends rapidly due to the failure of the control system, the elevator speed limiter will immediately detect the overspeed behavior of the elevator, trigger the elevator safety clamp and stop the elevator car on the elevator guide rail urgently.

Extended data:

The following situations may cause the illusion of "falling down"

1. If passengers enter the elevator, due to the elasticity of the elevator traction wire rope, with the gradual increase of passengers in the car, the wire rope may cause the car to sink slightly due to the load of the elevator car, forming a certain height difference with the elevator hall threshold.

2. Due to the debugging error of the elevator load measuring device, passengers will feel falling when the elevator starts.

3. Some elevators have excessive downward acceleration, which will produce a strong sense of weightlessness at the moment when the elevator starts. As the elevator accelerates to the rated speed, the sense of weightlessness caused by acceleration will disappear.

Passengers forget to press the floor button after entering the elevator because of chatting with each other. At this time, if someone calls the elevator from outside, passengers may mistakenly think that the elevator is descending.
