Elevators have become an indispensable vertical means of transportation for people's lives, and with the frequent use of elevators, faults are also added. Especially in the trapped elevator incident, it is very easy to cause panic and tragic events. What is the cause of the trapped elevator?

Taking Jinan City as an example, relevant statistics show that the Jinan City Elevator Safety Operation Monitoring Center received 9299 public telephone calls from July 1st to September 30th. The total number of elevator failures was 856, of which 505 were faulty. The number of trapped people was 351, and 1,164 people were trapped.


In the handling of the troubled people, 502 rescues, accounting for 99.41% of the total disposal; and 7 rescues (four of which dispatched the second-level rescue units to rescue at the same time due to large-scale power outages). It accounts for 1.39% of the total disposal. The “three-minute response rate” of the maintenance unit is 100.00%, and the “30-minute arrival rate” is 99.20%. The average time taken by rescuers to arrive at the scene was 10.66 minutes, and the average time spent on the scene was 5.90 minutes, which was far below the 30-minute arrival time set by the state.

Among the difficulties encountered by the trapped people, the reasons for the top three are: 218 external causes, accounting for 43.17% of the total number of faults; 118 for human reasons, accounting for 23.37% of the total number of faults; 60 for door systems, accounting for the total number of faults 11.88%. The above three reasons accounted for 78.42% of the total number of people trapped.


Among the human causes, 52 people were trapped due to the obstruction of the door due to domestic garbage, accounting for 10.30% of the total number of trapped people's faults; 19 cases of trapped people caused by the renovation of the door caused by the renovation of the garbage, accounting for 3.76% of the total number of trapped people Among the external reasons, 163 people were trapped due to power outages, accounting for 32.28% of the total number of trapped people's faults; 23 people were trapped due to short circuit of electric components, which accounted for 4.55% of the total number of trapped people.


Do you understand what is the cause of the elevator failure? I hope that my friends will love the elevator when they travel and protect their lives and property.
