The elevators in a high-rise residential building in Hefei frequently "strike"! What caused this?

Elevator strikes frequently in a high-rise residential building in Hefei. What is the reason? In fact, if the elevator breaks down, it will be very inconvenient for the residents of the building, especially those living on high floors. They are likely to climb the stairs to go home. Some people live directly on the 20th or 30th floor, which is a very painful thing for them, because it is difficult for them to go home after coming out, especially with children and vegetables in their hands. Going home from a business trip is particularly tiring.

However, the elevators in this high-rise building frequently break down, especially the elevators in a certain unit, which can be said to be broken at two ends every three days. Residents simply can't ride with peace of mind, because they are afraid that they will suddenly break down in the elevator one day. If they are in the elevator one day, it is actually very dangerous. Some residents have reported that this community belongs to the old community and has a history of more than ten years. Although there have been elevator failures before, they have not occurred so frequently.

From the photo, we can see that the display screen of the elevator is playing circularly. Because of the hot weather, the elevator is prone to failure. If you are trapped in the elevator, please press the door horn or button to call the police at the first time. But in fact, if you are really trapped in the elevator, the signal of the motor is very poor. It is very likely that at this time, the mobile phone has no signal and can't call for help, so we have to press the help button in the elevator, but in case the help button in the elevator is broken. So I think the property in this community should deal with this problem, instead of waiting for the accident to happen too late, and the elevator should be maintained to a certain extent.
