love watching all of the physical machanics of these machines. Computers are cool but to watch all this stuff work like a giant clock. so smooth

I watched a Ward Leonard set running an elevator and thought it was one of the most marvelous things I'd seen. To see that motor running at full speed then slow down to a slow crawl was amazing.

I had 4 of these, but the newer generation that used 1625 vacuum tubes for the directional circuit control LG, LJ XLG and XLJ and HS....and the diode matrix for the hall call circuits. PI plate selectors with the advancer motors.... The generators and the drive motors were absolute beasts... the controllers...maybe not so much, over 40 year career..hundreds of hours keeping it all running... I miss it. I enjoyed what I did and I think I was pretty dam good at it!

Type B MG sets and pie plate selectors! I still work on this type of equipment in LA! Still using the 2040 touch tubes in the car and still using the glass vacuum tubes at the top of the controller! Still has the original flyball governors! 👏👏👏👏👏👏

Very nice and impressive old Gearless DC machinery. 175 volts, 141 amps when I read the type plate correctly - so, about 22 KW or 30 HP of power. Great! I love these old DC drives. Sad that this technology now is obsolete and more and more replaced by three-phase AC engines.

It is built only using relays, but it functionality is very similar to modern elevators, powered by microcontrollers, inverters and other electronic stuff. Great machine!

I used to work on a geared version on this unit in San Antonio. Ironclad units. I rarely had issues with it. They knew how to make things last back in the day, that’s for sure! Thanks for sharing.

I love that machine room

My father was an elevator operator very briefly. Otis is the best brand by orders of magnitude. Keep running strong!

These things really are beautiful to watch.

Really cool vid, thanks for the tour

god I love the sound of relays working. You should make an hour video of that on a very busy day.

Worked on all of those machines over the years.Replaced field coils and white metal bearings on the gearless machines,comm skims and undercutting on site.Those Generators have exciters on the end which otis later modernised and removed.

spent a lot of years with those! Back when Otis was built like a tank!

True to a degree about the machines. Though incredibly built, those big gearless eventually need to get rewound.The good news is they do it onsite.Way too heavy to send out. We finally lost one about 80years old. The wire insulation deteriorates. You start getting hot spots on the commutator. They also start losing motor fields. DC drives too are becoming a thing of the past. Magnetek or the 12pulse MCE still work well. These days the AC gearless PM motors are the standard.

Your videos are great andrew

It's funny to hear someone trying to explain what they have little clue about in an utterly confident tone. I've been there many times before, too. Lol Nice video, BTW.

Very nice classics!

This video about the elevator and visit to its machinery room is fun to view.Reposted the link thru You Tube so more whom are interested about this can also view.Reposted YT link to facebook too.Enjoy viewing,this is fun!!!Thank You for telling its story!!!

Amazing!

amazing

Did you ever get the old parts

THAT SOUND! Lovin' it. Footage is great but little too short - want mooooooore! :)

Dieselducy is a real live train

Excellent!

This is so cool

Ive wanted one of the small ones with the old slate controller board, but yeah even the small are are insanely heavy! So all I have is a ball governor from one

If you want a complete controller, you might ask the modernization contractor if you could buy one of those being removed. Otherwise, they're just sold to a scrap metal dealer. There's a lot of copper in those old controllers and contractors may get as much as $50 a piece at the scrap metal yard.

Andrew Nice avatar/icon. I have that flag over my pic on my FB page. And funny how CBS 6 news was there with you.

Is it possible to get a machine room tour? I am super into mechanical stuff. I plan to major in Mechanical Engineering in college and work as an elevator service person.

I'm lucky I had the chance to work on the same type elevator in Bombay India at Hindustan lever Head office they had 3 of the same ones these generator had exiter for controllers to work D C volts was taken from the exiters and the fly ball governor the job is upgraded it was a master piece as per what I know never was the field coil short hats off for the workmanship and the manufactureing people of Europe.

What building is this in?

Nice motors.

Very cool!!!!!

Super videos greets from Poland

Had the opportunity to work on one.... tricky

what beautiful machines. This is honestly my true passion. I'm 21 but I want to get into the elevator business. I'm starting my electric class this semester. Please God help me study to become worthy of working for OTIS or another elevator company one day

According to the name plate on the machine, the machines are Otis 72 machines.

I hate to see these nodded! A question... What selectors are those? They look kinda different from the 6850? The pie plates are smaller and the frame looks different. I know WTC had some custom units but I'm not aware of what these are. Merry Christmas from northern Minnesota!!

1:41 Awesome old exit sign!

Super!

Very Similar To the Elevators @ the Washington Trust building

elevator only went to 6? they are compact yet powerful. looks hard to add another elevator.

At last I've found an excellent video to watch tonight - must have missed this one when you published it. Wow, amazing! Some things puzzle me though, mainly due to cost I suppose - Why Gearless in a relatively low rise building, and why do they have the more expensive "advancer" system (2:46) on the selector? Answer, for you to film :) but do you see what I mean? Most other buildings would have cut that out, unless the building was high rise and demanded these extra features. Glad you filmed the journey up to the motor room, always interesting so see just where they are and how to get to them - every building is different. EXCELLENT video!

good

Awesome DC motors! :)

Сложнее сделать тогда было нельзя. Поворотный указатель этажей просто великолепен. Размер редуктора указывает что лифт может поднимать больше 1 тонны. А размер контроллера - может автоматически открывать двери, готовить пиццу, ловить радио, сообщать биржевые новости, и вызвать такси )))

Where is this? I'm liftservismen from Poland.

Eu trabalho na Otis no Brasil. Eu tenho esse tipo de elevador na minha are. I work in Otis Brasil I have this lift in my area...

Is the motor 480 volts 3 phase what city is it in

Beautiful controller if you can read a print they will Last forever! The only thing on these cars i would mod is maybe the Selector !

Not? Fps??

You should've asked them to run the freight elevator a few times.

I am demoing a room in a roof penthouse on a parking garage with two of these motors in it using a torch and electric chain hoist to lower the pieces

Dear DieselDucy, What is the name of the builidng you filmed? From, Connor

old technology, elevator, there's a way not done yet, no cables machine. Just detection once you put your weight in elevator or escalator by means of detection the machine will take you up, mechanical timing process in every step, weight is the switch .

have you ever see a elevator he runs by a elektrik motor he drives a hydraulik pump and the ropes are driven by a hydraulik motor?

1958 ??? It is not possible and do not believe that it still works ?? !! Here it is cool ... wow

cool video groetten van Tony pino uit Nederland Hollanda

Kind of like the phone can kickers they used to use...

Very large D.C. motors with bristling copper commutators.

Is the speed like 500 ft/min

Subliminal message at 6:15

An elevator lift room comprising a drive, an electric motor in an upright position, a brake, and a suspension element for providing vertical movement of the elevator chassis. www.sunny-lift.com/Traction-Elevator-System---Gearless-Elevator-Motor-For-Machine-Lift-630---2000-KG-SN-TMMY05.html

ive been in a hydraulic motor room in school with a caretaker

@border the porter - i would guess 70s or 80's

They WILL regret moding that

Did you save the parts?

2:12 DC generator.

When I liked it. It hits 1k likes.

The fidget cameraman has to learn how to hold a camera so the video create no damage in the heads of the viewers.

I'm surprised that they used gearless units on such a short building.

This Very old version

0:18 he said thank you Lamar I didn’t know his name is Lamar like gta 5 let’s talk about Lamar wait I know a dude named Lamar

dieselducy, are you a mechanic?

Little walk down memory lane. I was an elevator consultant, later a safety inspector, for a couple of decades (I'm 73, retired) and I've been into many hundreds of buildings and inspected thousands of elevators, many like those Otis installations with Ward-Leonard & the relay-based controllers. I don't miss the 85 decibels of those m.g. sets or the kneeling on the carbon/dust floor to write my notes because a clip-board was a nuisance & there's hardly ever a table. Interesting electro-mechanical equipment though. Consultant's general recommendation: Refurbish Otis gearless machines, scrap everything else in the room. Use SCR. New door operators, fixtures, cab finishes. Refurbish hall/car door equipment & whatever's >60% worn (ropes etc.). But, as always, if somebody keen to get the work gives a great price for everything in the room being scrapped and A.C. gearless installed then likely go with that, a tidy package. If memory still serves.

Thomas Edison would have been proud

Sad to hear these elevators were being modernized...but that's progress. Pretty soon Otis touch buttons will become extinct. As it is they are getting very scarce.

+DieselDucy elevator heaven well i LOVE buses

100% Analog

Definitely not a safety first video...

I looked like crap in the video. LoL
