Sixth, being trapped in the elevator will suffocate? What should passengers do when a trapped ladder occurs?


Answer: The elevator car is not a completely sealed car. Under normal circumstances, the ventilating fan will keep working. When the power is off, the air circulation can also be realized through the car gap. Therefore, you don't have to worry about being trapped in the car and suffocating.


An elevator is an electromechanical device with a high degree of automation of motion and may malfunction due to various reasons. When the elevator fails, the safety protection device will stop the elevator and play a role in protecting passenger safety. When the passenger is trapped in the elevator, the correct response is:


(1) Passengers should keep calm, press the emergency alarm button in the elevator car or use the communication tools such as mobile phones to call the emergency rescue telephone or “119” published in the car, and obtain it with the elevator user, maintenance unit or fire control center. Contact, inform the ladder, and inform them to come to the rescue;


(2) Passengers should not forcibly open the elevator door to prevent falling or accidental injuries, and wait patiently for professional rescue.


Seven, riding the elevator sometimes feels "walking ladder" is going on?


A: One situation is that the elevator is in daily use. When the control system detects a component failure, such as a flat-level sensor failure, voltage instability, sudden door lock disconnection and immediate closure, etc., the elevator will be triggered. The safety protection function enables the elevator to run to the designated landing station or the base station to reset at the inspection speed (the national standard does not exceed 0.63 m/s), and reset the leveling and other parameters to resume operation. During the reset process, all the operating functions in the car will be temporarily disabled. Many passengers mistakenly think that the elevator has a “slide”. In fact, this is the “reset” or “return to the base station” of the elevator. The principle is similar to that of the computer. Restart, this is the normal self-regulation protection function of the elevator. Therefore, the passengers do not have to be overly alarmed. After the elevator is stopped and the personnel are evacuated, the elevator maintenance unit can be notified in time to check and eliminate. In another case, the elevator car is insufficient in braking capacity due to overloading, dragging the wire rope, etc., or the traction capacity is reduced, causing the elevator car to slide down, causing the elevator to "slide" phenomenon. In this case, when the elevator slide speed exceeds the set value, the speed limiter and the safety gear will act, and the elevator car will be stopped on the guide rail, and the elevator will stop running to prevent the car from falling to protect the passengers. In this case, when the passenger is trapped in the elevator, he should call the rescue call in time to wait for the rescue. This situation is dangerous, so it is strictly forbidden to overload when using the elevator, and it is very important to maintain the elevator.


Eight, what are the precautions for daily riding?


Answer: (1) It is forbidden to take the elevator when seeing that the elevator has a fence for maintenance and maintenance work;

(7) When an emergency occurs, immediately press the red stop button set at both ends of the escalator to stop the escalator.


X. What are the current requirements for old elevator management?


A: According to the "Fujian Province Elevator Safety Management Measures", when the service life of the elevator reaches 15 years, the user should entrust a special equipment inspection and testing institution to carry out safety performance technical assessment. The inspection and testing organization should propose to continue to use, repair, reform or scrap. opinion.


In general, the elevator has a service life of more than 15 years and is called an old elevator. The so-called safety assessment, which is a "full physical examination" for the old elevator on the basis of the annual inspection. The evaluation report mainly proposes targeted rectification opinions on the main risks existing in the elevator and the dangerous and harmful factors in the elevator system, so as to improve the safety technical performance of the elevator.
