The elevator facilitates China hospital elevator daily life and accelerates the pace of social development. However, in recent years, the frequent failure of elevators, known as the 'safest means of transportation', has caused a large number of casualties. It has sounded the alarm for us and it is necessary to raise elevator safety to the height of public safety. As a special equipment of electromechanical synthesis, the elevator is technically similar to a computer crash and the car stalls, which is difficult to completely avoid technically. Judging from the analysis of historical elevator accident cases, the trapped people often fail to get professional rescue in time, causing secondary accidents and causing casualties.
How to provide effective professional rescue services to the trapped in time is the key to avoiding elevator safety accidents. According to this situation, this article mainly introduces the working principle of elevators, the types of elevator accidents and the treatment measures. Keywords: Elevator accident cause rescue method According to the statistics of the State Administration of Quality Supervision, Inspection and Quarantine, at present, China's elevator production, elevator ownership, and annual growth are the world's first. As of the end of 2012, the total number of elevators in use in China reached 4.216 million, and it is growing at a rapid rate of about 20% per year.
The ever-expanding number of elevators has exacerbated the occurrence of elevator accidents. Statistics from the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of my country show that elevator accidents in China cause more than 40 casualties each year, especially since 2012, elevator accidents have been on the rise. In recent years, several domestic cities have experienced elevator shock accidents one after another.
The tragedies are shocking. For example, on April 10, 2012, an elevator in the Shanghai World Financial Center suddenly failed. Nearly 20 white-collar workers were confined in the elevator car and traveled back and forth between floors 1 to 52. Elevator accidents in Qianxinan Prefecture, Guizhou Province are also uncommon. For example, at 0:52 am ontwo people were trapped in the elevator on the second floor of the first community in Xingyi City, Guizhou Province.
