Was the Electronic selector replacement a modernization upgrade or something for lifts with failed selectors/temperamental ones?
No, Express never used a tape or connected mechanical selector, the system is very similar to telephone dialling selectors and just as accurate, one inductor on the car and two counts between each floor, they also used plates for levelling, door zone and speed selection of up to six speeds, where Otis had cams on the advancing motor on a tape selector express used timers to accelerate GF1-6 for generator field s and then FRI for field weakening to get the top speed, it had plates in the shaft to drop each speed step off and relay logic to reduce them one at a time with speed limits at the top and bottom of the shaft and a slowdown box on the car if over 2m/s. have a look at this to see one that is still in service ruclips.net/video/GB9203sDmUE/видео.htmlsi=mVWzpZH7IXy0bsb3
Do you get any Microprocessor, Variable Frequency controlled Express lifts over in NZ? Referred to as QVF Control I believe
I think there was a few installed in Christchurch, those buildings all came down after the 2011 Quakes so all long gone now
An interesting gear-less traction machine 4 V belts with pulleys on the motor and driven sheave. Instead of the more common direct bolting of the driven sheave to the armature. It's the opposite of a bench power tool like a lathe motor on top. A small motor, 6HP however running on 400VAC 3 phase 10 amps per phase.
Really interesting to see the P420 planetary gearboxes on the other side of the planet. Nice! I always thought these ZF machines were a European only thing.
They are certainly a very efficient machine, would be better with decent brakes however or two of them maybe
I worked for Express Lifts for 24 years from 1976 to 2000 started as an apprentis/trained fitter, moving on to Advanced and then Senior fitter before moving over to the management side. Great times and a great company until GEC and Winestock sold us to Otis and we all lost our jobs.
I remember the Otis lifts that my dad serviced in Sunderland, UK and the contactors had strange V springs on the front. Quite innocuous I thought until my 12 year old brain pointed that several were not connected. Apparently this fixed the fault.
This machine was built like a tank still going 80 to 90 yrs later, outside of the buzzing coil on one of the relays. 1st time I've seen a brake drum with two solenoids. Controller looks straightforward, magnetic motor starers on the top, up/down relays, interlock, break relays and the bottom reverse phase relays.
These 3 gear-less DC traction machines are marvels of engineering! They were built like a battleship day in and out operation. It appears to be more of an issue finding replacement pats nowadays, an elevator made just a few yrs ago replacement or FRU can't be obtained. I'm familiar with two Otis winding drums installed in the early 1900's which are still in service today.
We rebuilt one of these machines when a few segments of the commutator shorted to ground, total cost including removal and reinstall came to about 54k in NZ money, with a Chinese AC PM Gearless coming in just under 6k it was much cheaper to mod the entire site than rebuild the next one that failed about a year after. Only had two fail after about 50 years of service and these were within 100 meters from the sea
@@liftguy30wellington45 I've seen a few videos where a communicator on a gear-less machine was repaired when one of the windings/communicator bar insulation shorted out. Those machines you have held up well, with just two failing in 50 yrs. Yes that was expensive to remove/repair/reinstall with a new one far less costly.
No real markings on it of brand type. Probably built by the railways over 100 years ago
An interesting DC geared machine and controller. In reading the data plate on the motor it shows 13HP 200VDC 56A however the controller is 400VAC 3 phase. Curious the hoist motor is on a lower voltage. Unless being a smaller HP motor
It has a ward leonard generator set to convert the AC to regulated DC
@@liftguy30wellington45 at 1st glance it appeared it might be DC drive with the controller being newer, thus it was an MG set. Akin to the elevators at my old job, the controller was older microprocessors, however retained the DC traction machine and MG set.
What is this???
I’ve never never seen such a mix bag of lift equipment in my life 😂😂
What a great and odd governor! It is pretty much th Otis version alltough with the flyballs upside down. Very interesting!
Yes I remember it well 😂😂😂 401s
My service route otis was in the west end of London and my main base was New Zealand hse which was the New Zealand high commission and at one point, also consisted of Buckingham Palace and Clarence House
It was, can this be changed? Let’s hope I know more about lifts than editing video!
Looks like this recorded as a sideways video? Makes it very interesting to watch 😊
Why is it that all the electrics in lift motor room are not enclosed in cabinets?
There is a door for the control cabinet, it’s just against the wall in the video, as for machine guards these are always presented to the owner as safety improvements to keep people safe, not all of them spend the money however
I can’t believe this stuff is still going where do you work my grandfather must have worked on that type of gear when he worked for the company back in the 30s and 40s he could have stayed working for the company throughout the war as an engineer as the job was a reserved occupation but he chose to fight for his country and was sadly killed
I work in Wellington New Zealand, there are a lot of old buildings here, most were done up in the 90’s when the values improved or they were quake strengthened. Sad about your grandfather.
Thanks he was in the RAF lots of my family worked for the company I think initially because they lived opposite the factory 5 generations over 200 years of service between them I was the last
Very cool setup probably got pleanty of life in it, Do you know who distributed FIAM in NZ?
ECC (Electric Construction Company) sold Fiam and mostly Express gear, Semag were very similar to Fiam (same naming of relays etc) and was sold by Kone. Kone now own Fiam
Great video and really cool equipment. If you're back there again, is there any chance of seeing the actual lifts? (landings and car?)
This one sounds very familiar i was confused by the sound of the SMS motor but the SEMAG call button. Does this lift have a Schindler M call station and car fixtures?
Incredible!! Love the sound of relay controllers, not many or any left here in Minnesota. Other parts of the USA there are lots left but due to code changes here in 2009, all were pretty much forced to be replaced. There are a few exceptions for service elevators
I hope you work for Otis in my day if got your had a Otis service tool and you didn’t work for Otis the company would get you nicked
I even have an OMT for the 401’s however the windows version of the tool is easier to use
In my day the OMT was what looked like a suitcase with hundreds of overlays and somebody did get arrested from another company for using a service tool back in the 90s in London

Yep I worked on that equipment as a service engineer for Otis for 30 years
SUPERB VIDEO SIR I SERVED ROUND GUIDE WAY GOOD LIFT AT MUMBAI MAHARASHTRA INDIA ❤❤
Is it possible to obtain this diagram in image format?
I will get them scanned next time I’m in our archive
Great throwback to 1959 DC traction elevators, and their schematics. Very detailed diagram of the main circuits, floor relays, and call stations. No surprise these elevators had few break down or failed components over their service. They were engineered to be simple and rugged and last decades.
These gear-less traction machines remind me of the installation with an elevator system DMR I think it was New Zealand. Except, they were much larger massive driven sheave, double wrapped. The floor relays and selector were very precision engineering. These elevators were still powered by MG sets, which were mounted vertically. The building was a low rise just 15 floors.
PISS building had four of those, as did Rutherford house, Freyberg Building and the Breeze Plaza, they are all modernised now

I wasnt even aware that Express operated in New Zealand
Express was MASSIVE in New Zealand. For most of the 20th century, the two main players were Express and OTIS. Following the demise of Express, most of their lifts in New Zealand ended up being maintained by Schindler, who often stuck their own name plates in them over the top of the Express one. Many Express lifts also received Schindler modernizations. This is one of the contributing factors as to why Schindler remains the most popular lift brand in New Zealand to this day,
ECC was the agent from them in NZ, Schindler purchased ECC in 1990, GEC than ran express in NZ until 1996 when Otis purchased the parent company
ULP (Ultra Low Price)
Universal lift processor, made with a Sinclair ZX81 processor and would run anything from a hydro to a VFD
Reminds me of the DCP controllers that Express made, everyone called them "Dirty Cheap Processor" 😂. I'm assuming it would have actually stood for Digital Control Processor.
Never seen this brand before and that floor selector before. Certainly an interesting one and probably fairly bulletproof being so simple.
They used to make cranes and industrial switch gear. certainly gave less problems than what has replaced it.
Epic motor!!! I wish it was audible but the fan noise is in the way
Nice
Very unique machine saw it for possibly the last time before the new 7000s get commissioned. Would be interesting to see a video of the new machinery once in operation
No way! I work at the Hospital! wish I'd known you were involved with this!
My gosh, the sound of those gen-sets starting up!! Music to my ears
Wow! Amazing that it is still orginal as of this video!
Not for much longer......in the process of being replaced currently - first 2 cars nearly ready.....other two cars to follow afterwards.
let's see the Lift car inside please also I love this Lift company

How much less energy would a new lift consume?
Did Westinghouse build those motors ? They sure look the same
On another site we had DMR’s which were like a scale model of a lift running the switch gear driven by selsun generator and motor sets, these were built by express under licence from Westinghouse so it is quite likely the motors would have been the same deal, most of the early castings say “Bull” Express and Westinghouse were doing deals for many years
@@liftguy30wellington45 DMR is certainly rare there are not many left mostly overseas in places like Hong Kong where there are still quite a few express installs.
@@WaygoodOtis these are VVT (variable voltage Thyristor ) with GEC gem drives, We did service several Express DMR’s (a copy of the Westinghouse DMR) but the last one was in Dunedin and was upgraded about ten years back, DMR’s were in wellington in Freyberg, PSIS, Rutherford and the Breeze buildings
Old school relay logic. They look like British GPO relays, but I guess they are not.
Nice. Why 4 belts instead of one wide one? I can yhink of some pros 4 seperate belts have and of some cons one wide one has but curious what the real answer is
Those 4 separate belts were probably more readily available than the single. Especially back then whenever it was manufactured.
@@eastender74 yea that's what I figured!! They're also way easier to put on since you fight 4 smaller bands instead of one big one
seperate belts provide more traction from 4 times more wedging area, it is the sides of the belts that move the force as they wedge in the grooves. same as the ropes in the sheave, more ropes generally equals more traction (in a v groove not a rifilled sheave)
@@liftguy30wellington45 oh that's awesome thank you for explaining!! Didn't know that. Thank you :)
I don't understand anything that occurred in this video, but I enjoyed everything that occurred in this video.
Love the sound of electric motors and machines, in general.
Cool stuff man work on a lot older equipment myself here in the states. Can’t beat the old stuff as long as you have prints and can read the terminals.
Cool! "... just a few oil leaks... 🙂" How old's that???
Probably mid 60’s, in this city they used to pull down buildings and reinstall the elevator in another building, many were originally 500VDC and ran off the tram lines, when this power supply was shut down it was better to convert to AC than to install a rectifier as they were huge and expensive at the time
Amazing this equipment still survives to this day! Nearly every example of this in the UK has now been replaced which is very sad and its sad to see these lifts go.
Love to see this! Quitte rare today!
