However, with the development of elevators, the accident rate has been rising, brewing a scene of tragedy. Dalian Star Ma Elevator in its rising market share at the same time, frequent safety accidents, quality problems worry. June 27, 2012, I received the report of Daqing citizens, said that the use of the star in the area of the elevator accident frequent, after many times with the company negotiations, has not yet ... It is understood that Dalian star Ma Elevator is the world's largest elevator company-Otis Elevator Company's subsidiary, in the Olympic Games in Beijing subway nightmares occurred before and after many times the safety and quality problems, and this incident did not very good warning Dalian Star Elevator Company, in the frequent accidents, not seriously looking for the problem is to blame, User entrusted elevator Maintenance unit and elevator factory communication, up to four or five years of time in many negotiations without fruit, has not been able to give users a satisfactory response. Daqing beautiful Lake International star Ma elevator accident according to the complainant, the star Mary Elevator in the Daqing beautiful Lake International Garden Project on a total of 83 elevators, is 2006 and 2007 two installment and put into use. In the use of these four or five years, the components of a large number of repeated damage, frequent failures, frequent users will be locked in the ladder and unknown reasons to stop the ladder. User-entrusted maintenance units and star-MA elevator factory for many negotiations, star-MA elevator has been taking evasive, evasive approach, so far many quality problems have not been resolved. Star MA Elevator Technical conditions are not in line with national standards by the complainant reflected: in the course of 4 years of protection, the user and its maintenance unit summed up the quality problems of 12 elevators frequently, and in the communication with the elevator factory, star MA Elevator site investigation engineers have signed the 12 quality questions to confirm, Promise to return to the factory to report the analysis before replying.

And the Daqing beautiful Lake International garden community used by the star-Ma elevator is frequently faulted, run 15,000 times will appear 5 failures. According to the gb10058-2009 3.10.7 regulation, when the car door out of the closed position, the car door should have the following mechanical strength: with a 300N force, along the car inside the car outside the vertical role in the door of any position, the door security function is not affected.

Not in line with national standards. In addition to the other 10 quality problems, although in the elevator technical conditions of the national standard does not specify, but the parts of the perennial large number of repeated damage, frequent failures, another difficult to accept, its quality and safety worries.
