0:12 The first attempt to stop elevator is electrical switch . - for reduce demage elevator parts by safety gear If the elevator speed is still increasing this device mechanically triger safety gear :)
Correct sir…first stage is the electrical contact. That should stop the lift by the usual machine brake and, as you say less stress on the equipment. If the speed increases beyond a certain point then the governor is stopped causing the safety gear on the car frame to engage. That will stop the lift for sure. Many years..a working lifetime of installing, testing and working on lifts.
afaik overspeed governor is sometimes a parallel mechanism that is only responsible for pulling the break pad into the rail, so the shock load you mention exists, but not on the main rope but on the rails, which is acceptable, I guess
We have observed a routine electrical test process triggering the engagement of a speed governor in the video. In its natural operation, the arm cuts the safety switch to activate the motor brakes and then mechanically engages the cabin brakes. This is the result of the collective expertise of a brilliant individual and a century of combined experience in the elevator industry.
If you watch the cable? Once the pulley stops, the cable continues to slip for... 0.3s ish. It would be a big jolt, but it is certainly a lot better than an complete immediate stop if it didn't slip
It triggers the brakes on the elevator itself which get pulled by this rope. If the elevator still moves with the rope stopped by this governor the brakes get pulled.
speed governor shouldnt make any noise. Maybe the bearing inside the governor is broken. Check if the cable is traveling freely through the shaft and over the tensioner/governer.
The overspeed governor operates the clamping device (safety gear) on the car frame, it just have to pull it up against a spring, it has no load-bearing role.
No way this is how it works. Unless it is Zoolander's elevator for ants. That whiplash would rip everything apart and break everyone's ankles, knees, and hips. Maybe even some wrists, elbows, and clavicles too.
I am a Harvard expert graduate with a master in elevators and three majors in governors. Lemme guess: you studied navajo feminist history in primary school and graduated high school with a specialization in ethnic homosexuality?
@@keepcalmandenjoythedecline No mister, I finished mechanical engineering but that is irrelevant here. You don't need a degree in anything in order to be able to search a video on youtube about how the elevator emergency brake works. You also don't need a degree to make the logical connection between the fact that in this video, a real world elevator equipment was shown, and the fact that it actually works in real life ("No way this is how it works") and it breaks nobody's bones. The governor in the video indeed stops very suddenly, but that is irrelevant because the brakes actually do not instantly stop the lift, but instead bring the lift to a comfortable gradual stop when applied. It may be that my navajo feminist history degree has taught me to search this on the internet, or it may not have, but what is certain is that your harvard master's degree surely ain't helping your intelligence.
@@keepcalmandenjoythedecline You went to Harvard for a graduate in ELEVATORS? 😂😂🤣 What, did you drop out of engineering and they found you a corner to stay in or something? lmao "I got my degree in Elevators" hahaha
No, little soiboi, i graduated from Stamford where I studied the History of Harvard Experts and the Engineering of the Eras Tour. Now go back to riding on elevators in your school for ants and insects that can't read good and stuff.
Brake engaged, passengers successfully flattened.
Elevators drive at a few m/s they would fall at most
@@indian.techsupport Don't you dare disrupt my pancake world.
I've been on a few elevators during testing when the overspeed governor set like in this video. a car rated at 350 feet per minute, is uneventful.
@@kurtzimmerman1637 Your reality is factual but boring, thus I shall ignore it.

No sir.. Things not working like that.
This is a selenoid just prevent turning of the wheels so disabled rope trigger brakes connected cabin..

The solution to overspeed is to shock load the entire system to ten times normal forces?

I rode with a state inspector on top of many elevators and I will never ride in one.
Oh no I'm govooooooorning
And everyone’s legs are now broken 😢
better than legs and hips and ribs
Nope, they would fall at most... elwvators only move with a few m/s

Lol no, the stop is not instantaneous
@@TheAechBomb too right, iv been in an overspeeding lift 2m/s people fall, get sore ankles and knees, its not too bad
proto ftw
I'm no expert, but I think a violent stop like that is going to cause some physical injuries. XD
This steel wire stop only to engage the safety gear, elevator will slide a little to smooth the brake
@@ekhiw Oh okay, that makes way more sense lol.
really? i can found only this? There is no live action test or something like this?
Can that brake support the whole weight of the elevator all the dynamic forces involved with an abrupt stop
It triggers the brakes on the elevator itself which get pulled by this rope. If the elevator still moves with the rope stopped by this governor the brakes get pulled.
Thanks for the useful information, but how do I solve the problem of the annoying sound of the speed governor and what does this noise mean?!

It means bugger off stop asking stupid question you goblin
@@LuciferMorningstar-ix3lbI solved it already by asking specialists
How to edit parasites?
Oh hell naww and thats why i take the stairs 😂😂😂👺👺👹👹
It lost grip.
I think that this is ok because it reduces acceleration and forces on the elevator
Ok fine elevator weight and the rope strengh and quick stop bruh spark
What is the name of gov??
Senco E26 M-speed plus
So that tiny part brakes a heavy metal box, lol
The only thing it does is trigger the big brakes on the main hoist.

@@nrdesign1991 no it does not
@@talusranch990 What does it do then?
@@nrdesign1991 it pulls on brake attached to car and activates
Id want it to stop it sooner 😂
There are new regulations surrounding upwards freefall (brake failure) unintended movement, and emergency handwheel operation.
And kone monospace
bro it's not, Kone monospace is an MRL
You have electrical test not mechanical safety gear testing
Its kone ecodisc?
No
No way this is how it works. Unless it is Zoolander's elevator for ants.
