Really interesting to see such a combination, as the Dyn S was only used in combination with Miconic B (or E) around here.
Schindler 🤢🤢🤢🤢😂😂😂😂
Yeah this was the second lift I found on the fire map
Looked at the fire panel here and it appears there’s a second lift here which I think I found here as well. Won’t disclose it location for obvious reasons

I recall seeing this type of floor selector in previous video of Westinghouse elevator and/or similar ones. How many floors is this building? I see the machine is geared traction.
@@TheTheo58 9 floors in this one
You can tell the exact year of manufacture on the plate on the controller cabinet. Listed on the Serial number, 68/007 The number before the “/“ meaning the year. So 1968 for this one! Although I’m not certain if it is the year of actual manufacture or the year of commissioning. I’d imagine there could be as much as maybe 2 years between the two for larger projects, although I’m not sure. Probably is manufacture though.
@@Lift.Tracker Thanks for that, I will update the description.
How do these awesome motors slow down? The inertia of the cabins, adding the weight of the cables must be overwhelming.
@@milus2200 these ones were fed via the GEC Gem drives which are thyristor controlled, they essentially reverse the machine to slow it down if necessary same as the AC machines, DC machines have massive amounts of torque so if you reduce armature voltage with full field they slow smoothly, the field is actually weakened to achieve full speed. If you press the wrong relay in the controller when running at full speed the motor will change direction and go full speed the other way (with some rope slip). They are very powerful.
Obsessed with DC shunt motors.
In the UK this door operator was extensively used on local authority jobs
And a Otis service tool you would have the police after you for having one of them in my day 😂😂
@@philipcollins3849 now they are $40 form Aliexpress!
No doubt crazy back in the day they had to be reset every so often and if one went missing god help you 😂
I remember when they first came out it looked space age 😊
I always felt there equipment looked more ergonomically pleasing to the eye compare to our staff ( Otis )
@@philipcollins3849 Their DMR controllers were beautifully made, the looming of the wiring and switch gear and engraving was all very similar to what Rolls Royce were producing at the same time. The door gear however was a turd compared to a 6970 fed via a saturable reactor which was way over engineered
Yes 100% agree with you the 6970 was a vastly superior door operator apart from the oil leaks but they would run forever
Surprised that some sort drive wasn't fitted during refurb
We were offering PDL VF drives at the time but they were a lot more expensive (30k at the time)
Still in good operating condition 64 yrs later, Marriot and Scott built this machine to last. I could not see the motor data plate clearly, appears to be 420VAC 3P pulling 6/3/9A per phase depending on the input voltage.
That's insanely cool! An american style dry power pump unit in Europe!! We still use dry power units like that on brand new installs, but only if it's requested.
This is in New Zealand
@liftguy30wellington45 oh. That's still super cool to see this type of machine outside of North America! Is that a EECO valve as I've NEVER heard of one being outside of North America either.
It’s the same age as me 😅😅
Those are some weird machines.
Definitely not the most tasteful mod. Using PDL light switch fitting for a car inspection panel that is a first can make a good guess who carried this out just for the sale..
Yeah remember seeing loads of these in the early 2000s before Access Cards took over.
Ah! the old "Dalek" upright generators, this takes me back to my installation days.
Those same machines with the diagonal frame are used on tons of mod jobs in the US, this is the first time I've seen a video of one in another country.
maintenance of rope is poor
@@seenivasanragavan6828 you are not wrong, the whole thing is up for replacement
How rare is it to find a low on oil hydro lift in your country? They are waaay too common in the US lol.
Not rare at all, many leak especially those with tripple stage or inverted rams, some leak so much that they foam the oil which can then trip the rupture valve in the down direction. Many are being replaced with MRL’s when there is enough space in the shaft, 46-68 oil is $20 a litre here so leaks get expensive.
@@liftguy30wellington45 18 liters here is 49$ or 43.97 euro. AW-32 oil is what we use. Can you try and get a video of a low on oil machine cavitating at the top floor from the inside view? That would be cool.
@liftguy30wellington45 Here we still are making brand new holed hydraulic elevators, but almost all are now holeless Roped, but every company has an option for that still..
@@QEElevators New Install hydros are basically rare. Even freighters usually end up with a MRL. Interesting the US is still using Hydros so frequently
The date on the machine is 1937 so probably about right for the time. Not many left
Interesting traction machine with the rod and encoder moving this disk.
I remember these with great fondness, the Express "C" machine, probably the best geared machine made by Express Lifts. Then there were the next ones up, the "D" machines followed by the gearless. The "C" machines were originally fitted with Bull motors when used as 2 speed units but then changed to Ziel Arbeg motors for VAC operation.
This is incredibly cool, but another sideways video :) You might be able to fix that within your youtube video settings, but I don't remember.
Thanks I know more about lifts than I do about CZcams!
I’ve seen a lot of old Otis equipment and, as an old Otis engineer, installed some of it. I’ve not come across these before!
That's Manapouri power station, South Island, New Zealand isn't it? That is our second-longest lift (-220m), after Sky Tower's +225m 'Lift 4' (5m/s - KONE UltraRope). You're damn lucky to have got that video!!
Saw this one last Sunday lol
More wrong paint 😂😂😂who do you work for fair play you know your stuff
To be fair the building was derelict for many years but that paint was applied by Otis, can’t say who I work for here
Ok maybe the company you work for won’t like it you would to well in the uk the kids over here wouldn’t have clue with the kit your working on it’s mostly been ripped out in London
@@philipcollins3849 I like working on the older stuff, some of the new guys are keen but there is much to learn about Saturable reactors, Ward Leonard control, Air gaps in DC controls, suicide circuits, tape readers, valve timers, touch buttons with SCR or valve controllers with half wave rectified circuits,DC injection braking, AC levelling transducers, advance motors, pawl magnets, Selsyn generators and receivers, analog tachometers, magnetically latching relays……. all of which is now superseded by cheap AC VF or DC PWM control and an encoder, and if it doesn’t work you throw a new part in, and the diagnostics usually tells you what to replace.
Very true it comes down to one thing money
@@philipcollins3849 you are correct but I have removed your comment as can’t publish that here, I worked for the company they purchased in 1990
Dandy machines and controllers still in good operating condition. Interesting how the "pie plate" floor selector and floor relays are adjacent in the back. The two controller relay cabinets in front must be the main ones which control start/stop/ door open/close/interlock/ braking/ MG start and running. Unless they are a parallel feed off the controller cabinets for the floor relays only in back. They got it right on the installation 400VAC less current pull on the DC traction motor.
That’s a fairly straightforward 21 UCL, but that mechanical indicator drive is weird.
I have done another vid of the indicator drive
It looks like the landing doors used to be powered as well?
@@WaygoodOtis always been manual, used to be a few of these round town, all side opening, the two piece ones have a handle on the linkage
@@liftguy30wellington45 The Ropes and pulleys above the doors must be for the old analog floor indicators?
@@WaygoodOtis yes there is a rod that goes down the shaft that is pulled up and down by the gearbox in the machine room, each rod has a rope or string loop that goes around the shaft of the indicator, very simple yet accurate as would reset at the top and bottom if slipped or the indicator was moved
@@liftguy30wellington45 Ah thanks i was unsure what they were for but that makes a lot more sense.
Fascinating!
That what you call rough
Carpeted walls! What a relic!
In all reality it should have had a full upgrade or been left as it was
Horrible and that’s coming from an old Otis man Ps. Just to let you know my main job which I was based out of for 25+ years was New Zealand hse in the Haymarket which was and maybe still the New Zealand high commission
How many m/s?
I think 2.5
These are DC traction machines? And were originally powered with MG sets? And the mods with DC Drive? Interesting with the strain gauges integrated into the dead hitches.
They were DC express, they are now permanent magnet AC machines
Are the lifts going down to the Lambton quay still using Original machines they were partially modded some years ago but have received another mod only recently.
The doors were done first (qks9+ in the tower then wittur on all) still original machines in the low rise. They were express VAC1, there are still maybe 20 of those in service but parts are getting hard to find
Very impressive, a smaller footprint of a microprocessor elevator controller and hoist machine. Including an over-speed govenor. I see it's a basement traction machine, are there 4 guide sheaves offset on machine beans top of the hoist way or sheave room for the cab and counterweight ropes? 3 Phase 440-480 VAC?
We use 415 volts here, six sheaves at the top as it is roped at 3 to 1
Very interesting brake; I've also never seen an idler sheave on the governor before
I think it’s called a fly rope as the governor rope is not in a loop like modern lifts but connected to the top of the counterweight. Will pull in the safety gear if the hoist ropes stretch too much without the governor tripping
@liftguy30wellington45 thank you
These sound amazing! What year? 1980’s?
@@musiclabmn 1989 install
Dandy vintage geared traction elevator, controllers and floor selectors. Those were built "Otis Tough" to last for decades and be repairable. Were there originally four DC traction elevators as the MG sets were dual output? And the one that burned out one of those removed? I remember prior to starting a maintenance engineer position at a local hotel (one year earlier) I meet up with an out of town guest. They had two traction elevators. I heard this awful grinding noise from the MG set in the lobby elevator; could not have been the machine. I mentioned it to the front desk. I discovered upon hiring, the bearings were shot in the MG. Hmm wonder why maintenance did not shut it down? These were geared with a microprocessor controller.
One generator supplies a fixed voltage for control circuits, motor field, brake etc, the other provides a variable output to control the traction motor with a series field and inter poles in some cases to compensate for load, the smaller generator would be replaced by a simple rectified power supply on a more modern DC lift
Now we’re talking 😉🇬🇧🇬🇧🇬🇧🇬🇧
Thanks so much for putting out this content! So much we would never otherwise, particularly as what's still left of this equipment is dissapearing. Obviously it is ancient by todays standards but still so fascinating and sophisticated for its time.
Not so ancient. There’s still some us oldies still around who remember installing this equipment.
Hi, do you put videos of your cars and telephones on CZcams too? I just met you at the lift at St.Helens. Niki.
@@nicolaphillips7126 The other things are all on Facebook groups which is not as good as CZcams as it gets lost to history, bring on the vintage clothing :)
I love those old lifts...do you put your cars and telephones etc. on CZcams as well? ( I just met you at the lift at St.Helens.Niki.
