The weights are still noisy as they wear the rubber and clang, putting the weights in the door rather than beside it is a bad idea that increases the noise and weight of the doors. These days I’m always slowing doors to reduce breakdowns and increase safety

Rare? Probably only about 500 of them left in the country. Most were installed by ECC so weren’t badged FIAM other than the buttons, many were installed with express buttons as they looked much more modern at the time

I’ve gotten 10 in Wellington so maybe not rare after all

@@elevatorsinnz the one you did at Inwork house in Porirua is also a FIAM processor 2 speed AC powered

@@liftguy30wellington45 Interesting. Is it safe to assume, then, that most of the 1990's elevators with Express buttons are actually FIAMs? I know the 1990's was around when Express was being bought over by Schindler, so I guess it would make sense if they slowly stopped making their own lifts during the acquisition, but I'm not sure.

@@t3224.elevators_nz probably, Express was not purchased by Schindler, ECC were the agent for express so stopped selling them here when they were purchased by Schindler, GEC then opened another branch of Express that kept trading until 96 when Express was sold to OTIS

@@user2C47 the older versions had another encoder on the governor to compare and distance check, the coupling with four grub screws is very reliable but in many cases is the only speed feedback for the drive (which was originally designed for a crane)

@@Robbedoes2 the older ones are very well made but overcomplicated, generally if they are slow they are reliable (or under spec’s when ordered)

@@jaredleroy9876 It’s in the middle of Wellington and publicly accessible, most people see them as rickety old lifts rather than the work of art they are

@@jaredleroy9876 No, the door motor failed so a much faster motor (all that was available) was fitted to keep it going while the old motor has the bearings replaced, the DC injection has been cranked to full to slow the replacement motor or the doors would smash.

It goes between a kitchen and two dining areas

It says OTIS right at the start, you weeb

Quite right, I will add the word Elevator to the description, cheers

@@TheLiftDragon yes, depending on the size of the machine the drive was often in the same cabinet on the 411m

@@philipcollins3849 20 year expected life span, then you buy a new one, everyone makes money. The old stuff was 50 years which was the expected lifespan of the building at the time

20 years now that’s what I call optimistic I’ve seen gen2s worn out after two years

@@philipcollins3849 have you seen a gen 3 yet? They managed to make a cheaper model

I’m not sure I’m now out the loop once you retire that’s it I was involved in the original first gen 2s but towards the end of my tenure I saw some new ones which were horrendous and poorly built with bad materials on prestige sites

@@3ffrige I have found many many guys over the years asleep in the machine room! Despite the noise and heat, during fault finding before data logging meters when latching relays and paper and test lights were used it was easy to dose off while waiting for something to happen.

@@TheShinyGuru a lot of people seem to move between companies, probably get better pay every time they change employer, it seems too be a stable industry to work in

@@liftguy30wellington45 Some truth in that for sure - although I left Keighleys because I was to young to know when to shut up and explained to my manager _exactly_ whose fault it was a job went sour. Speaking truth to power isn't always a good career move 🙂

@@TheShinyGuru that is something we have all had to learn as we age, customer tells me these days that 2 plus 2 equals 5, I just replay with “you’re paying the bill, so you must be right”

We had managers that would promise the customer we could fix anything so some steep learning curves over the years, we used to be the agent for Express (who also sold FIAM in this part of the world). Have worked on so many different brands over the years, the Otis guys would have a boring job just fixing one type of lift I think.

@@liftguy30wellington45 The Otis guys back in the sixties, seventies and even the eighties were only really interested in installation. Most of the service work in the North East and I think elsewhere was picked up by Express. Dad worked on Express, Otis, Marryat & Scott, Electra, Pickerings, Hammond & Champness, SMS (which I suppose were Express) and probably a host of other makes that I can't remember. Never a dull moment as you say!

They are elevator motors at the top of a building lifting and lowering the buildings elevators.

@@ats-3693 thank you!

@@robertmclean6629 It is hard to tell they are elevators when all the ropes are covered with machine guards etc

@@philipcollins3849 The 411 and 413 that followed didn’t really offer the customer much more, the controller was much simpler however and easier to program with a test tool than having to write EPROMs etc, the early brake lift and pre opening doors made the 401’s really fast and smooth for the time

Someone said that the technology of the 401 came form NASA and then toUTC which was the parent company of Otis at that time

@@philipcollins3849 It dependent on a measurement from car to car which I cannot remember we had a lot in London also had rescue doors

Very strange I don’t remember seeing any high rise units on Otis like that especially new sites mind I have been retired for some time 😂

@@clivecoles1288 the big three put those AMD / Wittur / Kone operators everywhere, so reliable compared to just about everything else

It’s my understanding that a compensation sheave is generally in the pit on compensation ropes (to balance the rope weight) on a 2:1 roped mid to high rise, sheaves on top of car or counterweight are generally referred to as “divertor” sheaves.

I can make it reliable or quiet. Just not both! They really need a better switch arrangement with a smaller gap between on and off.

I’ve fitted a few soft starters before but they were thyristors with just a starting ramp. The lift is actually much slower to move than with star delta.

@@OrbitStudios-23 these are nantong indicators, cheap and cheerful

They will display a code on the car and bottom landing display, I’ve never ever used it, they are like a basic PLC control so I usually just run through all inputs and check they are correct state and always find my fault on the way. There are a few things that fail on them so I’ve modified most of those to be reliable on all units in wellington at least, the machine is no longer supported so it is a full replacement for a sheave failure etc

I remember seeing the promotional material for the “Schindler Mobile” we didn’t install any here, would be awesome to see one

@@psirvent8 the older larger gearless machines were mounted on the floor in the machine room, the double wrap divertor was generally bolted underneath so if you have the height of two big sheaves plus the distance between them that makes for a tall setup, often divertor sheaves are mounted in the top of the shaft which is very difficult to grease or service. To add the space underneath often gives more room for governors etc, originally this site would have had Otis tape selectors in the machine room too. So a wrap room below means the motor room can be slightly lower (comparing to all equipment in the machine room). It also gives much more space to work around rope hitches etc otherwise they tend to be buried in the machine support steel. The Otis DC machines were much larger than what is currently installed.

@@liftguy30wellington45 Thank you for the explanation.

@@daviddunbar5754 Hot and loud, and full of carbon and rope dust

@@philipcollins3849 when I started the company was too small to have such specialists (they used to fly people in from other countries for commissioning etc) so I did everything from installs, commissioning, diagnostics etc, the big money back in the day was after hours work and you got to see everything doing that, I never liked building sites or escalators but have dealt with too much of both

@@musiclabmn must be, still has ropes and weight on it, massive amounts of asbestos was removed or contained in this building so that is probably why it was walled over rather than pulled out

@@liftguy30wellington45If you go downstairs is there any evidence of where this was?
