In this case, what should I do if the elevator is trapped due to power failure?

1, turn off the main power switch to avoid sudden call;

Tell the people in the car not to mess around. The elevator has a five-way intercom with emergency power supply, and no cell phone signal is needed;

3. Pick up the handwheel of the computer room and install it on the host;

4. Use the brake release lever to release the brake, and another person will manually move the main engine (which side saves effort).

Other methods:

1, the best way is to wait for help quietly. Many elevators can accept cell phone signals, and passengers can call their cell phones for help. If you can't communicate with the outside world, passengers can use the weak light from the display screen of mobile phones and lighters to find the alarm bell and intercom bell in the elevator button for help. If there is no light source, you will always feel for all the buttons in the dark and press the alarm bell. If these devices are out of order, you can tap on the door or take off your shoes and call for help loudly and moderately to attract others' attention. Don't keep calling for help until the rescuers arrive. It is better to adjust your breathing, keep your concentration, observe the movement calmly and wait patiently for rescue.

2. After passengers are trapped in the elevator, they usually ask the building property management or 1 10, 1 19 for help. However, most of the above departments do not have elevator maintenance professionals, so it is easy to delay time or rescue accidents. To this end, Wenzhou Elevator Industry Association was established a few days ago, and an elevator emergency rescue center was established. The center has more than 200 elevator emergency rescue teams with professional operation qualification certificates, and has set up a hotline 56887222 to provide 24-hour free rescue service for people trapped in elevators and other emergencies. It is reported that it usually takes professionals less than 10 minutes to open a power-off elevator, which is very fast and safe.
