In February of next year, China's first national standard for the retirement of main components of elevators will be implemented.
Old elevator scrap will have evidence to follow
◆ Hunan Daily reporter Huang Wei
In recent days, elevator accidents have occurred in various parts of the country and elevator safety issues have received much attention.
Recently, in the symposium of the provincial CPPCC democratic supervision group, Li Shaoyang, member of the Provincial CPPCC Committee and Director of the Standardization Division of the Provincial Bureau of Quality and Technical Supervision, mentioned frequent elevator safety incidents. Several members said that they had personally experienced it.
“How many elevators are currently in operation in Changsha?” “The ownership of a house is 70 years. It takes about 15 years for an elevator to enter the 'old age'. Is the old elevator repaired or replaced?” There is no standard for the retirement of elevators. Who will pay for the transfer after retirement?” These issues became the focus of everyone’s discussion. The Hunan Daily reporter conducted an investigation.
More than 6,000 old elevator hidden crisis
These days, at the entrance of the third phase of the Taihe Homeland in Yuhua District, Changsha, the owners lifted banners with “elevator accidents are frequent and security issues are irritating”. The Hunan Daily reporter visited and found that there are one elevator in two units of the community, one in each of the four units, and one in the third unit. One of the elevators is stuck with a “temporary maintenance” notice, and the other two units have stopped using electricity. "The room that was delivered in 2010 will be broken in less than five years." "In the near future, there was a lot of elevator failures. Repairs and stoppages haven't solved the problem." Residents in this area resented indignation.
The person in charge of the residential property Fangtai Hong Property Co., Ltd. explained that due to the large number of custody and training institutions in the Thai baht area, the elevators are frequently operated every day, and the parts are depleted. Three failed elevators have already passed the quality warranty period. Owners' views on elevator maintenance expenses are inconsistent and they have to be shut down. When the reporter asked whether the elevator had qualified inspection marks and daily maintenance, the property side did not answer positively.
In mid-July, the Quality Supervision System of Hunan Province launched the 12365 “Director's Wiring Day” event “You take the ladder and I solved problems”. Another real estate in Yuhua District, Emerald Cloud, was reported to have hidden safety problems. The 2 elevators in the 2 blocks of the residential area have passed the annual inspection and the elevator operation is unstable. During the elevator ride, the elevator will emit a “zizzi” sound. Also often appear to lose layer, shaking, card layer, noise, light floor and running the actual floor is inconsistent.
In June of this year, the news of “A Changsha woman crashes from the 19th floor to the 1st floor to death” is even more shocking. The incident occurred in Block B of Hongjing Mingsha Building in Changsha City. After the landing door and the car door were opened, a woman did not notice that the elevator car was still on the way up. When she entered the elevator, she was tripped to the entrance of the car and received the elevator car. Squeezed with the inner wall of the hoistway, and then fell from the 19th floor to the elevator pit. Two days later, another elevator next to the fault occurred, and three more faults occurred within one hour. According to the relevant person in charge of the management office of Hongjing Famous Building, since the opening of the residential area in 2003, there have been 12 years of history. Due to reasons such as the useful life, the seven elevators in the residential area frequently suffer from sleepy people and slides.
The Hunan Daily reporter learned from the Changsha City Bureau of Quality Supervision that there are about 52,000 elevators registered in Changsha at present, and the old elevators have reached 11.52%. Among them, about 4,500 elevators have been used for 10-15 years and 1,353 elevators have been used for more than 15 years. At the same time, there have been more and more unexpected incidents such as elevator failures. In recent years, there have been more than 200 incidents of elevator failure every year.
According to the survey conducted by the Bureau of Quality Supervision of the Municipality, the most complaints about the safety of elevators are frequent failures of elevators, slides, and control systems; elevators do not have annual inspection certificates or annual inspection certificates expire; long-term elevator outages affect the normal life of owners; The elevator rescue is not standardized and the elevator management is not handling it in time.
Replacement of the available house repair gold
At present, the old elevators in Changsha have many problems such as backward technology, parts aging, and many problems. How are these "sick ladders" and "elderly age" "over-ageing" elevators remedied? The cost of replacing an elevator in a high-rise residential building is 20,000 to 300,000 yuan, and a house may need to be replaced three or four times in 70 years of property rights. Where is the elevator replacement fund coming from? This is a big challenge.
Using housing maintenance funds is one of the solutions.
According to the relevant regulations, the application for the use of special maintenance funds for the property must be “two-three-thirds signature”, that is, the owner-occupied part of the property management area accounts for more than two-thirds of the total area of the building and accounts for more than two-thirds of the total. After the owners agree, they report to the Property Maintenance Fund Management Center for filing and apply.
However, with the increasing number of old elevators, it is difficult to completely rely on maintenance funds to solve the problem. Especially for some unsettled house maintenance funds, or unclear property rights and insufficient funds for old houses, the cost of replacing elevators is more problematic.
Actually, our country's laws and regulations have clearly defined this. Article 79 of the Property Rights Law stipulates that the maintenance funds for buildings and their ancillary facilities belong to the owners. It can be used for the maintenance of common parts such as elevators and water tanks, as determined by the owners. According to the "Special Equipment Safety Supervision Regulations", if the owner fails to agree with the property company on the replacement cost of the elevator when purchasing the property, the cost of replacing the elevator shall be borne by all the owners.
“In fact, the safe operation of elevators depends not only on the number of elevators in the building, the quality of elevators and the quality of installations, but also on the daily safety management, maintenance and quality of passengers after elevators have been put into use, and passengers’ civilization and so on.” Luo Liuqing, Director of the Special Equipment Safety Supervision Division of the Bureau of Supervision, said that elevator maintenance and car maintenance are the same principle. Every 5,000 km of the car must go to the 4S shop for inspection and maintenance. The elevator also needs regular maintenance to ensure the comfort of driving. And security.
For example, an elevator that operates in a 12-story residential building runs an average of about 300 times a day, and runs for many years, and the loss of parts and components is inevitable. Therefore, for elevators that have been put into operation, if the use of units does not enhance normal maintenance and maintenance, there will be security risks.
Luo Liuqing introduced that, generally speaking, installation and maintenance companies need to get the “Installation Maintenance License” above the provincial level and have relevant qualifications to install and maintain elevators. The normal maintenance of an elevator needs to be twice a month. Taking a 10-storey elevator as an example, the maintenance cost of an elevator for one year is about 5000-6000 yuan.
The frequent occurrence of elevator accidents is related to the non-standard maintenance of the elevator maintenance industry. In order to save elevator maintenance costs, individual property companies only asked the elevator company to overhaul the elevator once a few months and compressed elevator maintenance premiums to a price of 3,000 yuan or less, and even invited some “guerrillas” who did not have any qualification to conduct maintenance. Bao, because the maintenance personnel did not have qualifications for special equipment operations, severely disrupted the order in the lift maintenance market, and left security risks.
Whether the elevator will be retired for next year
15 years is regarded as the upper limit of elevator service life, and most of the elevators in question are near or beyond this period. However, at present in China, there is no clear requirement for the use of elevators for scrapped years, resulting in an indefinite period of “lifting” of some elevators.
“According to the elevator complaints and accident laws received by the quality supervision department, the old elevators have a high failure rate and require strong repair technology,” said Wang Jian, deputy director of the Hunan Provincial Quality Supervision Bureau.
In 2014, for the sake of ensuring safety, Changsha City promulgated the "Changsha City Elevator Safety Management Regulations", specifying that when the elevator service life reaches 15 years, elevator use managers can commission elevator inspection agencies to evaluate safety performance technologies. The results continue to be used, repaired, modified or scrapped to ensure safety."
According to data from the National Standards Committee, by the end of 2014, the number of elevators in use in China had exceeded 3.5 million. Due to various factors such as design, manufacture, installation, maintenance, and use, the service life of the elevator is very different. Therefore, it is difficult to formulate the standard for discarding the entire elevator.
In July this year, the National Standards Commission issued China's first national standard for the retirement of main components of elevators - "Technical Conditions for Retirement of Main Components of Elevators", which will be formally implemented in February of next year. It will be scrapped or not by formulating the technical conditions for scrapping the main components of elevators. Judgment, then decide whether the elevator needs to be scrapped. This document has filled the gap in the elevator industry in the absence of relevant standards for elevator scrap over the years, making it possible for elevators to be scrapped.
In the next step, the National Standards Committee will also accelerate the development of the National Standard for the Retirement Technical Conditions for the Main Components of Escalators and Moving Walkways, improve the national standards system for the retirement of elevator products, and continuously upgrade the safe operation level of old elevators.
