The ELEVATOR SAFETY BRAKE video ...'all safe gentlemen'

MrChay could be in a bit of trouble if the cables in his animated lift were to snap! For this reason, every lift (or elevator!) has a SAFETY BRAKE!
But how does it work?
..........
Please give us a 'like', thank you! :)

TO SEE OTIS MACHINERY IN ACTION, this video has it all: (and took 2 MONTHS to edit!!)

IMPORTANT NOTICE ABOUT SAFETY AND YOUTUBE:
This is a RESPONSIBLE and RESPECTABLE channel.
My channel does not promote or glamourise dangerous activities like lift surfing.
A warning in a video DOES NOT exonerate you if harm should come to a kid that was copying something that YOU have portrayed as a fun activity.

THE MRMATTANDMRCHAY CHANNEL, established 2008:
I'm passionate about uploading quality and interesting videos for YOU, my audience.
What is my channel about? "Old lift machinery made interesting", old air-raid sirens, prehistoric alarm equipment. If "I" don't find it interesting ...then IT DOESN'T GET UPLOADED!
I always spend a lot of time editing my videos with animations, video in-sync with music and voice overs to make them this way.
My moto - "Quality NOT Quantity" - spending a month editing a video is not a rarity!
But without you, I'm nothing here. Thank you so much for watching.
...mrmattandmrchay is me (Matt) and my son Chay.

THANK YOU very much for watching :)

Thank you for this video. My preschooler was distraught about the time we'll spend in elevators on vacation, and getting a glimpse behind the scenes helped a lot.

[What_The_Fuck_Did_I_Just_Watch]

It's always fascinating how those things work!

[dykodesigns]

Elisha Otis appearantly demonstrated the safety break in public to convince people that his invention was safe for human transportation.

Interestingly modern lifts are also required to have protections for if a lift were to overspeed in the upwards direction, or if the lift were to move unintentionally

The old motor start ups are so beautiful!

[Josh.Davidson]

Fantastic video Matt. I am always fascinated by these types of mechanical devices

[rayfridley]

Many of the older elevators have a flyball governor, just like those on the early steam engines. Two metal balls are held by brackets to a rod that rotates when the car is moving. If that car speeds up beyond a certain point, the balls would lift up by centrifugal force, bringing up a collar that first operates a switch to shut the motor off, and second, could mechanically tightens the cable, pulling on the car brakes, stopping the car.

I was looking up about this lift accident that happened 3 years ago in a hotel lift in Killarney, Co.Kerry, where the lift fell down three floors and injured 5 people. I thought if the lift was in trouble it would freefall up to the top floor and hit the roof. The article is called 'Company fined 750, 000 euro over Killarney hotel lift that fell three floors'.

Thank you for your videos! I’ve recently become super intrigued in the history of these machines and took an apprenticeship test and scored an Ohio Union elevator interview this coming week!!

[Dana_Danarosana]

Nicely done. Man, that mess at 5:00 was crazy! Was that the first time the test was performed or was that frame just metal fatigued over time?

[scottsliftsX]

I love people that are really informative about lifts

[sebastiannielsen]

I personally think the frame wasn't "poorly built" hahahaha but more that the lift engineer did test this in a very bad way. The lift seems to be pretty new, and there should be a test button in the service panel to test the brakes without actually applying them fully.

I mean, the frame was not designed to handle the load of the lift car AND the counterweight AND the motor working against it because brakes were applied. Guess that lift engineer was new on this lift and didn't get instructions of "NEVER test the brakes on this lift by impeding the brake cable. ONLY test by designated test button".

IF a real fault happened that would mandate brake application, then the frame would of course crash too, but then its "worth it" to save lifes.
This is EXACTLY why you should NEVER play or use a emergency stop if there is not a emergency. Because things can fail or break during a emergency stop, as opposed to a controlled stop.

Very interesting this video about of heritage of the old elevator since it is... How was terrible it could be fall out of it!

[starlite]

I just got on the on-call list for the apprenticeship program for our local IUEC! :D I'm at number 112 so it could be a month or a year before I get called :(

[toddhunter]

I live in a high rise block and recently saw the lift engineers carrying out some maintenance work on one of the lifts, I says am sure you get asked this all the time but what stops you if the cable snaps he laughs and says sarcastically, the ground!! But then says if it was that easy to kill people we wouldn't be in business, you're safer riding in a lift than being in a car on the road.

[qeelevators]

How many lift motor rooms have you been in? I’ve been in 27!

[powerdrinker]

Can we put enough magnets on a elevator and put a layer of copper around the elevator shaft it to slow it down if it fails? Make the magnets deploy if it fails or you pull a switch. cost to much

[asetatlikalem]

İ just watched 2 of your videos and now im starting a elevator company

[morthren]

Great explanation and well put together video Matt

[MichalM]

Very informative! Nice video once again!
