This Ots equipment was/is known as 'standard Housing' as it was installed in many blocks of flats, sometimes as a 'Skip Floor' installation each lift serving alternate floors one for odd floors and one for evens floors. Much of the equipment it was prefabricated aluminium alloy entrance and arrived on site pre assembled frames very basic.

This buildings over the road from me it’s become a visual monstrosity

Left-handed highway exits in North America are rare, but they do exist. There’s one a few miles from my house, which my brother takes when he goes to university.

Really neat buttons though

The buzzer is actually the nudge mode it normally activates if the doors are open for too long

Sooooo sad for the nice elevator😑

The house is probably abandoned, what a shame!!

We’re are those lifts

Ill be honest this elevator/lift doesn't really look like something that belongs in the UK like those fixtures look very US to me

10 stories and only one elevator?

GUERRILLA PUBLIC SERVICE!!! YAY!!!!

COULD YOU IMAGINE LAYING IN BED ON A COLD MISTY RAINY NIGHT AND THAT GOES OFF WORRIED THAT SOME LUNATIC HAS SCALED THE WALL AND ESCAPED?

What is the purpose of the small pulley on the floor?

Makes me feel good always taking the stairs

Bicycle "Bottle" Dynamos actually generate AC.

Installed 100's over 40 + years

Visited this one today, not in action sadly but was still cool to catch some photos of it!

Visited this one today in action! It’s still going strong 💪 sounds really healthy too and nice catch you got there Matt!

Ur first vid 😊

I’m gonna miss this wonderful sirens

youre opening an elevator school where pepole have to take elevators instead of stairs😂😂😂

Erie and cool. I'm used to the fire sirens here doing a much shorter wail cycle

It seems like diode banks would make more sense than the motor generator setup. Was it more cost effective or more reliable to have this setup? I realize this gives three voltages. But ac voltage change is easy with a transformer.

what happened to one of those down arrows

Another masterpiece. You are the Stephen Hawking of elevators. I'm going to have to watch this a few more times just to absorb all the info. Any tips on maintaining audience retention in your videos? I seem to lose everyone after about a minute. Thanks for the video.

Oh My THEY ARE STOPPING A LIFT AS A TRADITION WHAT THE

I can relate to this but in a different way. I have phobia of Water heaters / Geysers. (Reshuiqiphobia) I am actually afraid of every big cylindrical object kept at height. It's really difficult to explain.

Why were the controls not put into lockable cabinets? Extremely unsafe in my opinion.

Nothing scary about it 👎👎👎👎👎👎👎

Playing with the flaps reminds me playing with a fidget

The 1974 Otis disabled lift survived until the car park was closed in 2021.

Was this recently abandoned at the time?

Excellent video, loved how you used highlighting over the original schematic to show the operation.

Amazing elevator and video! 👍

Very nice Schindler elevator 👍 it looks like 1940s

derelict meane abandoned

The Motor Is In Good Shape For Over 100 Years Old

Hey! do you still record sirens now i love secomak/klaxon CS8's

Lexan!

Super! Nice!

I ALWAYS LOVE UR VIDEO'S

Magnificent work and super detailed as always!

siren hello guys 65656📢📣

Just brilliant. Gonna have to watch that again.

LOL "The choke is CURRENTLY turned off." - A little electrical humo(u)r there.

Electromechanical relay ladder logic is just beautiful, and you did a good job with it :)

We still have several of these in service in Wellington, NV was an option to drop the main feed due to lack of power supply, in this country they all had a phase failure unit connected in this point in case someone reversed the mains on the street or that one phase was down causing the motor to run the wrong direction, the overloads are timed solenoids as mentioned above. The Chokes purpose is not to smooth the mains but to reduce the voltage to the slow speed motor essentially giving you another speed step and to protect the slow speed motor from overload, generally the motors are 16 pole vs 4 pole so levelling speed is 1/4 running speed, when running through chokes (or resistors on cheaper units) this allows more of a ramp down to the levelling speed. Chokes also didn’t need to be changed for large or smaller motors as would resistors. The contact on the brake was always called a cooling contact but it also reduced the back emf when the brake was disconnected reducing the flash on the contacts, less voltage on the coil also makes it drop faster giving a more accurate stop.

new video !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Great episode, fantastic attention to detail as always, Nv- my thoughts as others have said would be that it cuts mais power to the cabinet, that would then require an engineer to attend, because if its over travelled something has gone fairly majorly wrong, ie contractor jammed in so cutting the control circuit wouldn't make any difference. We have over travel switches on filters at work, that run up and down on railway track, if they miss the turn around limit and hit the over travel then they stop dead and need maintenance to attend. Each filter weighs about 6 T so it can make a big mess if they over travel.
