“Elevators have been reviewed by the national special equipment inspection department before they are put on the market.” Cao Wei, head of engineering department of Andersen Elevator Sales Company who had represented Otis Elevator, told the reporter, “The Otis Type 513MPE that has failed The two fixing bolts of the elevator base are broken, which is the quality problem of Otis Elevator. The responsibility cannot be shirked. However, the elevator operator should also take responsibility.”

“Actually, we are also victims. We will recover from the accident.” The Beijing-Hong Kong subway spokesperson once expressed at the news conference on the subway line 4 accident held by the Beijing municipal government that the elevator operator in the accident was injured. On the side of the Hong Kong MTR subway.

After the “elevator shock” was staged at the Beijing Metro Line 4 Zoo Station, the above two parties' speeches were constantly disorganized and the security risks of elevators had left a shadow in the hearts of the public.

A few days ago, the Beijing Municipal Bureau of Quality and Technical Supervision announced the preliminary findings of the accident on Line 4: Otis Elevator (China) Investment Co., Ltd. (hereinafter referred to as Otis) 513MPE type elevator has quality problems and maintenance is not in place, Otis The responsibility for this incident cannot be shirked. It is understood that in December last year, Shenzhen Metro also experienced a rapid retrograde accident with the Otis 513MPE elevator, resulting in 25 passengers were injured.

"The same type of elevator has the same problem in a short time, which shows that Otis's elevator quality is indeed defective." said the above-mentioned personage Cao Wei. According to him, Otis has an internal rectification system, and the company will re-examine the parts that have more problems. If there is a problem, Otis will completely replace the problem accessories to avoid potential dangers. Obviously, the occurrence of two major security incidents shows that Otis’ internal rectification system has not played a role, and Otis can't escape it.

Not only in Beijing, at present, many places have exposed Otis Elevator safety problems. The crash of Shanghai Elevators and emergency stoppages in Ningxia made Otis, the “big boss” of the elevator industry, the object of questioning by consumers. It can be seen that at present, on Weibo, many people have expressed their distrust of Otis brand.

However, in the condemnation of many parties, there are also industry insiders that although Otis is the main responsibility in the accident, but elevator operators should also bear certain responsibilities.

“Because of fierce market competition, many elevator operators will reduce elevator maintenance costs in order to save costs. This has caused some elevator maintenance companies to engage in vicious competition, and has greatly reduced the number and quality of elevator maintenance.” Cao Wei said in a word. .

Excessively lowering maintenance insurance contract fees is considered to be an incentive for Beijing-Hong Kong subway safety risks. It is understood that Beijing-Hong Kong MRT is the first cooperative enterprise to introduce foreign capital in the urban rail transit field. The huge amount of investment in the early stage, coupled with the low price of the Beijing subway, will inevitably be too much for the Beijing-Hong Kong subway.

Cao Wei said that even in the case of low prices, the current maintenance cost of each metro heavy escalator is also around 7200 yuan per year. However, according to media reports, the maintenance cost of every heavy escalator in the Beijing-Hong Kong subway cannot meet the standard. Compared with the state-run Line 2 and Line 5, the maintenance cost of Line 4 is even less. But even so, Otis is willing to sign and maintain it. This kind of "one willingness to fight and one willingness to fight" is also common in the elevator industry.

It is understood that due to the fierce competition in the elevator industry, elevator companies will try to "satisfy" operators' requirements for prices when the operators bid on elevators. In terms of elevator maintenance, elevator operators mostly choose low-cost maintenance companies, and the technical level and operating specifications of these companies are doubtful. Moreover, even if the elevator company can repair the damaged parts, it is not uncommon for operators to adopt non-replacement or shoddy methods for cost-saving considerations. And these all lay hidden dangers for the safety of elevators.

In this regard, Professor Liu Ping of Nankai University School of Law believes that elevator safety is jointly guaranteed by elevator manufacturers and operators. Therefore, elevator manufacturers and operators have joint responsibility in the event of an elevator problem. It is the responsibility of the stakeholders to protect the personal safety of consumers. This requires elevator manufacturers to strictly control the quality of elevators in accordance with national standards, and elevator operators should also be responsible for the maintenance of elevators.

Although Otis had made a big comeback in China, Cao Wei did not think that the accident could bring opportunities for other domestic elevator manufacturers. “After all, there is chaos in the elevator industry, and any elevator manufacturer can't control this kind of thing. Only when production and maintenance are done, elevator safety can be guaranteed. However, in the current situation, it is still difficult to be foolproof. ."
