When the elevator has "stuck floor" and other faults, the elevator will automatically stop running, which is an automatic protection measure of the elevator. If this happens, we don't need to be nervous and panic, because the elevator is equipped with safety fall protection device. Once a fall occurs, the fall protection device will be firmly stuck on the tracks on both sides of the elevator slot to prevent the elevator from falling. At this time, you should press the external call button in the elevator at the first time and contact the property company. The property company will notify the elevator maintenance unit in time. The maintenance unit will generally arrive at the scene within half an hour in the urban area. During the waiting period, if you hear a sound outside, you can shout loudly to attract the attention of passing pedestrians. In particular, don't try to open the elevator from the inside. This is because when the elevator fails, the circuit of the door sometimes fails. At this time, the elevator may start abnormally. In addition, the trapped people may fall into the elevator shaft if they open the elevator door blindly because they don't know the floor position when the elevator stops.
