I have always had a fear of elevators mostly for the drop. But this video has helped me understand better. Maybe now I just have to b worried of being stuck inside.

No children should boycott schools and learn from home. Schools are prison.

​@@praisekjames7628 yeah, school is slavery too

HUGE thanks to you for ensuring these mind-blowing elevators are working safely and efficiently. Earlier today, I went to the top of the city hall in my city via elevator, and my respect to people like you increased immensely.

@@Snowy-oq4ur I really appreciate your comment

Is it normal for elevator have gap 50cm between elevator and the wall? In my place there were a woman just died by accident in elevator, she doesnt realize those elevator had 2 door and while the elevator still moving she got panic cuz the door doesnt open. She tried so hard to open the door, once the door open she quickly get out and fall to the ground.

@@simsimi1227 That is a sad story. If the elevator cabin is between floors it can be possible to have a gap of 50cm from the cabin to the wall, but if the inner door is closed you are always save. Never try to get out of an elevator when it brakes down, you are always save inside, just wait for the engineer to get you out of the cabin savely. That woman didnt have to die if see just waited.

@@Rockzor98 yeah it sad, she just fell from 2 floor to G floor. And the body just found out after 3 days. Most people blame the design of the elevator like why it had 2 doors, why it had gap between the wall and the elevator but it also the woman fault cuz she dont pay attention which door has open. She panic, and try so hard to open the door while the elevator is moving once it open she quickly get out

Tbh id much rather know how an elevator prevents accidents vs how it actually works

Either way there's more to them than most ever see. The control system gets pretty interesting too.

1:00 How an elevator works. Everything else How an elevator works SAFELY and EFFICIENTLY.

that is the most important thing

Do you think preventing accident is not "working"?

Okay fellow 9 year old kid

@@confusedsperm9521 why are you fighting?😏

@@gamepool8517 cause it seems obvious with the emoji and stuff.

@@apple26j I feel like we're past those times of "only kids do it" anyway, I'm an adult in my late 20s and emojis became widespread when I was still in my early teenage days... Time flies 😅 before that we used text emojis :D I still prefer them sometimes :p

@@officerjohns9554 you're showing your age if you think emojis are only for kids, cuz kids of yesteryear are now adults and they still use them. How the time flies eh?

Yes

no

no

In such systems, chains or ropes are attached to the underside between the counterweight and the cabin, thus balancing the weight of the rope

and I have been wondering by how much you can increase waiting time and decrease speed before more than 10% of the people take the stairs

the IT behind it is easy if you got the hardware. on the internet you can find codes about that easily thats not hard. and put in some microcontrollers. wire those to the motor. and its done. all the safety mechanismes make it way harder to build. I built a 4 story lift. about 1:20 size. but without a couple safety mechanismes. only counter weight and damper

@@Knightfire66 that is totally not what he meant though, anyone can download code. he was asking about the logic of the software.

@@ersetzbar. why are you speaking for him? maybe hem ent the code itself.

Because people don't weigh the same. If the certificate told you that only six people could ride the elevator safely and six 300 lb people tried to squeeze onto the elevator it would surpass the maximum weight for safe operations, but by quantifying the maximum weight instead of bodies various numbers of people can board and ride the eleveator all within the maximum weight threshold. And it just takes the law of averages to calculate the weight of a group of people. Based on hieght and BMI one can safely calculate a rough estimate of weight of a group of bodies boarding an elevator. Besides a good rule of thumb would be comfort will "outweigh" safety. Not many people will want to crowd into an elevator that has too many people cramed into it, thus reducing the chance that too many people will occupy the lift.

As an anecdote: I was once traveling with a high school group in Washington D.C. The hotel we stayed at had us on four different floors. One evening after we had gone to a show and dinner six of us (we were teens) crowded onto an elevator that already had four adults on it. Two more people squeezed into the car, and the outer doors didn't even close when an alarm buzzed and a panel lit up saying the car was too full. A voice them came over the speaker (security or maintenance) requesting that the car clear. My friends and I decided to get off and allow the others to ride and waited for another car.

There is a seperate electric cable

This wasn’t meant to be an all-inclusive video. Just the behind the scenes mechanics of it all.

This is about mechanical systems, not computer controls.

@@oldtwinsna8347 oh, ok... thanks =)

As a elevator engineer too i can confirm the lift shown here is out of date. The motors used on modern elevators arent even roughly the same.

Most likely Blender

Welcome to Final Destination 6

In this case, the drive would have to be designed much more powerfully, since in the worst case it would have to move the entire payload. In small residential buildings, however the counterweight is increasingly designed to be only 40% heavier in order to save some more energy, since full load is only rarely used here will
