Why does an elevator break and kill people, and does an elevator really die when it falls?

After the bottom of the elevator touches the ground, there will be an upward reaction force, and at this time the momentum of the human body is still downward, so at this moment, the human body is equal to the momentum of its own close to free fall and the upward momentum of the bottom of the elevator, which is fatal to the human spine. In addition, after the elevator falls, it will deform, and even the top will collapse, so the damage caused is more than that of jumping off the building by yourself.

Won't you fall to your death? So much impact. It's like jumping off a building

But this rarely happens.

Even if the elevator cable is broken, it will not fall completely.

If you think about what the consequences will be if an elevator falls quickly at a height of more than ten meters or tens of meters, you think about it, I don't need to say.

However, high-quality elevators have safety measures, which can greatly reduce the failure rate and the harm caused by accidents.

Even if the elevator cable is broken, it will not fall completely.

The elevators have safety measures, which can greatly reduce the failure rate and the harm caused by accidents.

Elevator dead people are basically caught to death.

Because the elevator has always been relatively fast, if you suddenly stop people, you will hit something.

There is a fall arrester in the elevator, so if the wire rope is short, it won't kill you. The elevator will get stuck on the wall. The chance of being killed by the elevator is probably smaller than the chance of the landlord jumping off the building to commit suicide, so the landlord is not too worried.

Because the elevator is at a high place, it falls down all at once, so it will kill people.

It's equivalent to jumping off a building, do you say you don't die?

Of course, the elevator will die if it falls.

First of all, when the elevator falls, the person and the elevator accelerate down together, and the speed is as fast as the elevator. Falling to the ground, people are injured or even killed by the extreme impact force because the elevator touches the bottom, and the extreme time changes from high speed to stop.

If you do what you say, the elevator is picked up a moment before it bottoms out. If the force of the jump is not strong enough, the person will still fall at a higher speed, and will still be injured or even killed. If a person's jump reduces the speed of his fall to a width that will not cause him to be injured, then in an extreme period of time, a great bounce force in the legs will cause the person's speed to change rapidly, then this great bounce force itself is enough to injure or even kill a person.

If you are trapped in the elevator, you must first calm down, stay calm, do not take drastic behaviors, such as jumping around, adjust your breathing, and try to inhale and exhale smoothly and slowly. Because in the limited space of the elevator, the amount of oxygen is also limited, and the body consumes less oxygen when it is calm, so try to stay calm, so that the trapped person will not be suffocated due to lack of oxygen in a short time.

It is possible that when the elevator falls, the person and the elevator accelerate to descend together, and the speed of both becomes the same. Falling to the ground, because the elevator bottomed out, in a very short period of time the speed of the lead reed carried from the maximum to zero, because the person was greatly affectedImpactwill be injured or even killed.

If you encounter a sudden fall of the elevator, you can quickly press the buttons on each floor, and the entire back and head are close to the inner wall that is not close to the door, in a straight line, and the wall is used as a spinal protection. When the elevator is falling, you can bend your knees and lift your heels at the same time to stand on tiptoe. Borrow the knee bend and tiptoe position to withstand the pressure of the heavy blows, increase the cushioning, and reduce the amount of damage received.

Safety gear has appeared in modern elevators.

It will allow the elevator to lose all support force in free fall in the case.

It can also be reliably stopped. So don't worry too much about the elevator falling.

What is the reason for the elevator crash, in fact, the so-called crash here is not the CPU crash of the main control board, unlike the computer we use in our work, the power failure and restart will return to normal after the crash, but because the main control board detects a more serious failure, in order to ensure safety and take a protective measure. That is to say, the elevator will work normally and safely after the problem is fundamentally solved by professional maintenance personnel. After the elevator has this kind of protective shutdown, many people often cut off the power and then send power, as long as the elevator can continue to run, they think that there is no problem, which is very dangerous.

If the problem is not solved, this situation will occur frequently, so here we suggest that you do not rush to restore the operation of the elevator, but carefully analyze the fault information prompted by the main control board, find the problem point along the vine, and then let the elevator run after effective treatment. In this way, the operation of the elevator with low failure rate will be ensured, and the safety will be greatly improved. Here we will deal with the situation of the elevator "crash" to make a brief introduction, hoping to give you a little inspiration and use it in practice.

When there is a "crash" phenomenon, don't rush to cut off the power, but first look at why the fault on the main control board is prompted. For example, if there is a "brake switch error", it means that the action of the elevator brake switch in normal operation is inconsistent with the actual setting, and the power transmission system may be re-run when the power is off, but it is very dangerous to do so, and once the brake is really faulty, it will cause serious accidents such as slipping or rushing to the top. This is how we should deal with this situation:

First of all, find the cause of the fault, check whether the brake switch is broken or the action of the brake is not sensitive, or there is a problem with the line, etc.; Secondly, troubleshooting, if the brake switch is broken, replace it, set it again if the setting is wrong, etc., until this fault will not appear again; Finally, clear the fault records according to the fault clearing method in the following table and run it again. The specific process of analyzing the cause of elevator crash is as follows: after this process is processed, we can fundamentally eliminate the troubleshooting, and there will be no "crash" situation at the beginning.

Therefore, when we encounter similar situations, we should not rush to cut off the power and re-run, but fundamentally solve the problem, so that passengers can take a more comfortable and safer elevator. In addition, there are some minor faults in the elevator that do not affect safety, and the system will resume automatic operation, but there will be fault records in the main control board. Every time the elevator is maintained, it is necessary to call it out for inspection, so as to maintain the elevator in a targeted manner.

The possibility of a completed elevator falling is very small, and there are very few elevator accidents that cause death due to elevator falls.
