Elevators were invented several centuries ago. How is it possible that in the 21st century, there are still a number of cases of people getting stuck in elevators? I have gotten stuck in an elevator myself before, and have anxiety about entering an elevator ever since.
So I would like to know, what causes elevators to get stuck to the point that it requires outside intervention?
Why can't (or shouldn't) it automatically recalibrate itself?
Is it more of a mechanical issues or electrical issue?
Does an elevator getting stuck indicate a serious issue with the elevator that require maintenance, or is it something that can happen to even newly installed elevators?
Will we ever be able to fully prevent elevators from getting stuck?
- Occasionally, I may hear a loud bang when riding on an elevator. Although luckily the elevator does not get stuck. Why does that happen?
- In some elevators, a person stepping into the elevator will occasionally cause it to wobble up and down, as if it is trying to realign itself with the floor. This tends to happen more often if the person is heavy in their footsteps. Is there a reason to worry in this situation?
- Some times, an elevator will start beeping even though it did not exceed capacity. After the door closes, the beeping stops and it proceeds as normal. Why does this happen?
- In what case (if any) would getting stuck in an elevator be life threatening? (Assuming the person remains perfectly calm and will only attempt to leave the elevator under the guidance of trained personnel)
