Very detailed OTIS LIFT MOTOR ROOM video (ALL MECHANICAL!)

See the machinery working AS ONE, slow motion, synchronised camera views. It's VERY detailed and TWO MONTH's of editing!!
There is still a PART 3 yet to come, where I go into a lot more detail how this all works, in a way that ANYONE can understand. It looks complex, but when you break it down it's actually quite simple(-ish!).
This is Part 2, to see Part 1 go here:
..........
VERY RARE to be able to still see this classic generator of lifts still working, and even better to be able to film one in such detail.
Special thank you to PETE LOMAS for your help as usual, and NATHAN KACHMARSKI for the last minute info :)
..........
Please give us a 'like', thank you! :)

Here is a sideways view of the solenoid that raises the platform on the floor selector:

If it wasn't for HDTechLogic, I wouldn't have filmed this motor room! Visit his channel here:

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.
I've seen recent evidence of kids surfing, or attempting to surf lifts. It goes without saying that YouTube is a public platform and our channels are popular with kids, and kids are influenced by what they watch. I'd like to think THESE KIDS DIDN'T GET THE IDEA FROM MY CHANNEL.
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 :)

It will be interesting to see what questions arise from this video, looking forward to them.

Great Video worked for Otis for 45 years put many of these lifts in and replaced a good few. these lifts were top of the range in there day and could and do last for over fifty years if well looked after.

that 2 months of editing was definitely worth it, fascinating to see the old equipment in action from all the angles!

[highvoltage]

Love the slow motion, makes it much more clear to follow

Nice view of the flow selector in action. What a piece of machinery, replicating the shaft and the car (sort of) to do all the logic. People would tell, "tons of moving part, many things can fail" .... but since this was pure quality, this wasnt the case. If not, it wont be still running till these days. Using a generator .... this is pretty good solution to control a big motor accurately. I have watch a vid about the speed war of the lifts that high speed needed a certain profile of de-acceleration to make the passenger confortable. It wasnt just a two speed, but a certain curve of variation. They obtained this with a machined rod going in and out of an inductor and this was traduced into field control for the genset to control the actual DC. The time where power electronics were unknown.

What a great video, starting with an old building, the spooky flashing light.
Following a very interesting artwork of mechanical marvel.

[chriswilliamson]

Absolutely brilliant. I really enjoy all of your videos.

[mrclucker]

Absolutely fascinating!!! I re-wound parts of the video to watch the relay sequence a few times - to think all this is now contained in a minute chip!! Can't wait for the detailed explanation (I have some idea's, but want to see if I am correct!)

Thank you for your wonderfully detailed videos - they are the next best thing to actually being there!

[adrianodemetrio]

Amazing technology and amazing video! We really appreciate your hard work

[MichaelAStanhope]

Beautiful machine. Working on it might be a nightmare, but i'm willing to bet its more reliable than the modern ones that will unfortunately replace them.

[Phantomthecat]

Thanks for taking the time to edit these videos so well. I look forward to more detail on the operation - As an older Electrician I learned relay logic in open cut coal mines in Victoria, Australia, so I’ve always been much more interested in what is now termed ‘old school’ than PLC’s and Microprocessors although I have been dragged into the 21’st century and now program such things for a living these days. 👍

[BenDeSwert]

That DC generator makes such an eerie sound. Could be a horror movie background noise 😁

[HDTechLogic]

Nooo! I missed the premiere :( video was really good though, thanks mrmattandmrchay! Really enjoyed it! High quality... as always. :)

Software implemented in metal, switches, and relays.

[kevinmurphy-steele]

I remember exploring an Otis machine room just like this in one of my buildings at university (a carelessly unlocked door!) and was in awe of it. It was actually even more complex as it was an Autotronic system so there was a giant relay computer dispatching the cars. You have to hand it to the men who came up with that system, and the fact that the job of all of that stuff can all be done with a few chips and circuit boards these days.

[pomonabill]

FANTASTIC!!!! Your effort always shows, and this is NO exception! Can't wait for the explanation of the floor selector and how the disks operate.
Nothing like carbon and copper (brass).

[LiftyGamez]

Love these lifts and their selectors. Far better than the crap Otis makes today

[shawnaburns]

I absolutely love this video ❤️ I've always wondered how the components worked together now I know!! Very cool video 👍🎉🎉🎉thank you❤

[andyfinlay]

Fantastic video as always... Love the sound of the DC converters bogging down under load as the lift starts up! Also, moving parts like the Sheaves and governors have safety cages for safety. But none on the DC motors? So, it's OK to jab a finger in there? (Yeah, it's really really not!)

[p.m]

Excellent video. You can tell alot went into it. Really nice to see the different camera angles all together. 😎⚡👍
