IMPORTANT NOTICE ABOUT SAFETY AND RUclips:
My channel does not promote or glamourise dangerous activities.
It goes without saying that RUclips is a public platform and our channels are popular with kids, and kids are influenced by what they watch.
Everyone is different. If you're an adult, then I don't particularly care either way - you're responsible for your own actions. Some kids are better at gauging what's dangerous and what isn't.
My channel I hope does not plant ideas in their minds like to surf on top of lifts or perform stunts at height. I've seen very recently an example of this, a kid copying someone in our community.
In my opinion, 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. If you have shown it, they copy it, then where does the fault lie? Is it the kid? ...or the adult that planted the idea in their head in the first place?
I'd like to think that my channel DOES NOT influence people to perform dangerous acts.

FYI - I am an engineer by trade. I did not gain access to the lift shaft or tamper with any lift equipment. All filming was done from observing the lift in normal operation.

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 :)
Great video mrmattandmrchay!
Really interesting to see!! You don't get many Pickering's nowadays :(
Thanks for the channel redirect! It's really cool to see this lift!!
It's been a pleasure! To see a sample of the Otis motor room shown at the end of the video, see a sneak preview of it here on HDTechLogic's channel: ruclips.net/video/j-W3JVzfc1E/видео.html
@@mrmattandmrchay thanks for the pinned comment and footage! Much appreciated! More on email.
Súper interesante e increíble el funcionamiento de los elevadores, desde niño me apasionan.
Wow, some of the components in there don't look like they've been dusted since...well since installation?! Shame that that controller is indeed updated but its still got that awesome big heavy-duty motor. They ain't built like that anymore that's for sure. Epic vid!
Thanks. Yeah lots of character still left in this old lift :)
Can't wait to see that Otis "pie plate" selector! It's one of my favorite pieces of machinery.
Indeed! And even better its a dc genset and dc motor.
It better not be modernized
One thing that I've noticed.... with the new controller the motor makes a much nicer sound on a VFD... Although, it's a HG Trislot. It's gonna sound good... and these are the single speed ones that don't "whoooop!"
Mrmattandmrchay mrchay has in my opinion the best quality channel on elevators and conveyance systems anywhere! So marvelously detailed beyond compare!
Subscribed for years now! Love it!
Terrific video, many thanks. I'm trying to learn more about elevator roping systems and this is what I believe is referred to as a 2:1 overhead slung configuration. The drive pulley is twice the size of the pulleys attached to the top of the counterweight and the car. This is one of the many ways of equalizing the weight on both sides of the drive pully.
It sounds so amazing!
There were two lifts in this building, this one makes the best noises (sounds like a dodgy bearing making that growling noise!)
I see that the outputs have opto-isolators in them. Those 4-pin ICs are quite telling.
Yes, absolutely! Easy to identify, as you probably already know, they save external connections and unexpected voltages from blowing the board (an optical barrier).
Great footage, interesting old lift machine, motor sounds nice at 46 Hz.
Very cool video again! A few months ago I found a Pickerings machine from 1975 here in the Netherlands. Machine and logic were still in original condition. But sadly that lift will be replaced soon :-(
Wow cool! I really should have revisited the vernon bldg before it was updated but too late now. In particular the floor positioning system... whether it was roller switches in the shaft or something else.
6850 selector video should be interesting, i'm looking forward to some of the questions that will come up about that bit of kit.
What was the reason for running the motor at 46Hz on the new controller, when it was obviously designed for 50Hz?
Good question! I personally don't have the answer, but I'm sure someone will. My guess is, the motor lasts longer if not ramped up to maximum operating speed - but on the other hand, it's been there since the 1960s! Perhaps that is a default setting on the VM drive for 'HIGH' speed.
@@mrmattandmrchay I don't think the actual top speed matters much. The ramp up/down for the speed sure makes a difference, as a gradual speed change is always better for the parts than an abrupt change. Maybe the reduced frequency (and this is just a wild guess of mine) is to comply with some newer regulations that limits the speed for lifts that have doors that you could poke a hand through and potentially touch the shaft wall. I wouldn't be surprised if it is something like that. ;-)

The motor looks to be rated for 11,5A/8.3kW. Perhaps they choose an 11A/8kW VFD and limited max speed and power slightly instead of buying a larger and more expensive VFD. It could also be a European VFD that only goes up to 400V, frequency is directly coupled to voltage and this motor needs 415V for 50Hz.
Fantastic video as Always keep up the good work👍
Thanks
@@mrmattandmrchay your welcome
Good video, I like your videos because your explications and shooting are very explicative!
I only upload stuff that I find interesting which normally means that Ive certainly spent lots of time editing them. Thanks for the compliment
Ah, this building again. I remember.
Relays are gone, new s*** is here. :'(
I actually wonder... is the lift still "Out of service"? No? Hmm.
This boring display.. just.. whyy??
And... amazing video as always, matt!

Good video!
Very good video. You are the best. Carry on.
Thanks :)
Perfect video
Thanks
Simplex mode - only 1 call at a time
Love that motor
Yep...at least this wasn't replaced (else I might not have filmed it in the first place)
After all, it seems it is a single speed motor, but with a VFO. Given that, they should have done a better job, instead of trying to emulate a dual speed controller.
3:37 Did the brake replaced to two brake coils ones?
2:31 This is the brake. The springs you see at 3:37 are just return springs to apply the brake (two springs make the brake pressure stronger). Therefore 3:37, when powered it releases the brake. When the brake is de-powered, the two springs apply the brake and hold it there.
Does this lift have two motors running in parallel? I see two sheeves on top of the lift car so there must be two in the motor rooms as well. I couldn’t quite see how two cables would be driven from a single motor.
That's a 1:2 roping ratio - it's a goods/freight lift and it's like this to carry heavier loads. Therefore, the ropes do not end on top of the lift car. Instead they go around two sheaves on top of the lift car then back to the motor room.
From the start - they terminate (see start of video) beside the governor > to the counterweight > back up to the motor sheave > back down to the counterweight, then it's diverted to the other side of the lift > back up to the plate where the overload switch is.
So there is only one motor that drives this roping system, but the motor sheave has to turn far more times to move the lift compared to a lift that connect direct counterweight to lift car.
Hope that makes sense!
Mr Matt is correct. In the states we call it a 2:1 roping. It moves half the speed but you gain twice as much lifting power. Its easier to understand if you see the roping scheme in person or you can google. Mr Matt and Mr Chay, you guys make superb videos! The best on the internet! Keep it up...And I love your disappointment when you open the cabinet only to find the new controller instead of the relay logic!!!
The 2:20 music seems like a broken minecraft haggstrom
I'm certain I must be dreaming
modernised controller AND modern buttons?
[brain encounters critical error]
Yep but most of the original character is still there including motor else i probably wouldn't have filmed it.
Council housing? It looks like.
Nope, it's a low cost industrial building - people rent the 'units'. There's about 5 units per floor.
You are interested in your country for a half day city tour
Definitely not an 'Express Lift'! It makes the right sounds, but it is a shame about the modern controller.
Yep but i would have been surprised if the original lift was still there. But i suppose most of it still is.
Modern controller better.
Hi how is everybody
Good thanks Oscar. Hope you're ok too?
