Pressing 'UP' to go DOWN? What's the logic in that?

You probably DIDN'T need to know this, but if you ever find yourself in this situation, you'll know why!

[@kar27k]

Now I wonder after watching explanation of how this system works... Would blocking lift 1 in ground (1st) floor and calling it with up button on first (2nd) floor would call staff only lift? So would that be a way to bypass restriction of key switch?

[@mrmattandmrchay]

That is a superb comment! I never thought to try this, and I wish I'd included this as a possibility in the video content. Yes! So if there was a problem with the passenger lift, then the staff lift would automatically pick up the calls. Unfortunately there is no way to test this theory now, as the RH lift has been modernised :/ On the other side of the motorway (south), the RH lift call button is just 'switched on' using the keyswitch if the left lift fails.

[@FinnishElevators]

@@mrmattandmrchay That's actually pretty clever, that if the customer lift is out of service, it will call the staff lift

[@fr3akymurk]

It is interesting that you still comment on old videos, still this explenation is very detailed for the unskilled people in electronics. i also like your motor room / elevator tours.

[@passacaglia28]

As always, I love your videos as well as your background music. Not only does the piece you have selected sound like "elevator music", it also sounds like the background music I hear when waiting to speak to a representative of any given company while on the phone; "hold music". :)

5:05 - I never liked those Response Alarm bellboxes with the solar panel. That one is installed inside too!

[@mrmattandmrchay]

My guess is this was done as a temporary DIY solution! The alarm box certainly doesn't do any compliments to it's surroundings!

[@al66class59]

Ok, that’s pretty cool! Have liked the lift stuff despite not really having much interest (although anything electromechanical is nice!)

Wow, I love the end of the video, showing some parts of the tower of Hilton Park. As you did with Lancaster Forton Service tower, will you upload a separated video showing all the tower? I can't wait for it!! :)

It's a shame that the Hiltion Park Service Goods Elevators are knocked out it would be better to have it still intact.

[@MichalM]

38th! Very nice! Edit: Ooh! Very interesting. So many abandoned goods lifts, unusual building design on the inside! Looks like it could all easily be ripped out (excluding the lifts) and put back into service!

[@vinchenzo6845]

Nice video. Shame they replaced and modernised right lift now. Left still there and working

[@stephand4017]

Some lifts if you press up, it locks off the lower floors.

[@mrmattandmrchay]

Indeed, you press a lower floor, the button lights up but then goes out afterwards.

[@HardDriveGuruOfficial]

Do all elevators that expect to go up when the up button is pressed do that?

[@ag6371]

Aaaah that music is just so perfect for lift videos, Heritage Elevators used it too!

Cool I like the lifts old lift need to be more common

[@upanddownadventures]

3:09 I don't think i have seen this happen in the US, even on old Otis installations. Not sure if the logic is overall different, or if it is similar, but an extra circuit exists that prevents both the lantern lighting up for up & down at the same time.

[@Razaak666]

Interesting. I remember being at a ski resort in France. There the hotel we were in went from Floor 11 (the exit, confusingly), down the mountain to Floor 0. With two lifts, one of them was stuck on Floor 6 (and indeed, upon calling from Floor 6, the lift opened, it just wouldn't go anywhere). Calls were seemingly disabled from the other lift: it would automatically go straight down from 11 to 0, and then call at every floor on the way up. Is this common?

[@richardyoung1053]

Interesting to see where the resturant used to be.

[@guitarplayerforu]

How does the Otis Logic work in a 3 lift configuration?

[@Xanthopteryx]

Well. you said that you cannot reprogram relay systems, but that is not true. It can just be more cumbersome to do. A computer program is logic written in software. You reprogram by changing the software. A relay system is logic written in hardware. You reprogram by changing the hardware. Here is a cool article (Swedish only sad to say) about the safety signalling system in Stockholm subway ("tunnelbana"). I'm not sure if there are lines left with it because they have migrated to a computerized system but this was at least running for decays! It's so amazing that someone constructed this and that it works so well! techworld.idg.se/2.2524/1.253031/sa-fungerar-tunnelbanans-sakerhetssystem

[@mrmattandmrchay]

Thanks for the link. Love relay systems! Yes, relay system can be 'reprogrammed' by adding relays, changing the schematic, etc. However, not only do you need the hardware to do so, you also need the knowledge :)

[@Xanthopteryx]

@@mrmattandmrchay Well, that goes for computers too in fact. =) We have some really old programs at work, and no one knows how to change the code, and the software it was written in doesn't work on modern operating systems, and almost no computer have floppy drives and the code is on floppy.... I'll take "hardware" like relays any day a week compared to this! =)

[@mrmattandmrchay]

@@Xanthopteryx Good point. I'm just looking through that subway safety system link now, very interesting!

[@Xanthopteryx]

@@mrmattandmrchay I totally agree. It's amazing what you can do with relays!!! And using the rails to send signals to the train, and one more cool thing, yet as of today, no serious accident has ever happened because of signal failure! (of course, derailment caused by broken rail but that is not the signal system that failed). And when they started to switch to modern computerized system, it had to be backward compatible since you mix old and new trains. Another fun fact regarding the subway in Stockholm: It's the world longest art exhibition, 110 km! 94 of the 100 stations have different art on them, composed by around 250 artists. It goes from around 1950 art to modern art. They even have guided tours and a special app. So if you goes here sometime, take visit =) sl.se/en/eng-info/contact/art-walks/

[@daytontang3148]

I think some Mitsubishi, in my experience the new ones, you can press the up call button at e.g. 11 floor, but press the 1 floor button, it will close the doors, and the direction will change immediately. It's a nexiez mrl, so no physical relay logic and panels as such. Maybe it's a Mitsubishi thing?

[@compzac]

No pretty much all modern lifts will respond to incorrect landing calls by just proceeding in the direction of the floor you requested, as long as theres no other calls, so say you pressed up, when the lift arrives you goto press 1, but slightly before you pressed it another landing call above your floor was pressed, the lift is in the collective state up so your call is essentially ignored till the lift finishes all up travel calls. the idea that occasionally passengers make a mistake and press an incorrect button is built into the programming of modern lifts. But this is relay logic, unfortunately relay logic operates a little more rigid and slowly, otis had the design that the lift arrives at a final call in either direction for speed, cause with say another lift like express, schindler or Westinghouse, if you pressed up and then selected a call in the down direction, a lot of times the lift would have to close its doors, then open them again to be able to switch direction, as when they arrived they were in the direction you selected

[@stephand4017]

KONE lifts, If you press up then select a lower floor, they do not move and reset, then start moving

[@dykodesigns]

Odd that staff can’t call the goods lift from the ground floor. Wouldn’t the single button normally call either lift? I.e. the one that is closest to floor.

[@mrmattandmrchay]

This depends on the complexity of the system. With computers 20 years away, relays and mechanics ruled! To keep the logic simple, two lifts shared 3 landings. If you connected the up button to both lifts, there wasn't an easy way to detect which lift was closer. In the late 70s Express developed a system using resistors. The further the lift from a call, the higher the resistance. The lift with the lowest resistance was nearer and dispatched - but this is more complexity, more knowledge required to fix it and ultimately more costs. So it was easier to wire the left lift to the up button and the down button to the right lift. To see this in action see here... kzbin.info/www/bejne/pYqUgp95pryCqdU (my previous video)

[@imaxjunior6531]

@mrmattandmrchay The right lift being converted to Staff and Freight use does that mean that the maximum load for that lift was increased to handle the weight of freight?

[@lettybaylon9375]

2:30 STOPPED

[@UNIX32]

What if you did this on a modern day lift E.G. Kone ecodisc?

[@mrmattandmrchay]

The call buttons are attached directly to a circuit board which is addressed - so you can have many of these on one cable, each one has it's own identity. When a button is pushed, this circuit board sends data up to the controller. All these small circuit boards are connected normally on 3 or 4 wires - 2 for power, then 2 for data. Then software takes over! So it's a different era and completely different methods.

[@ag6371]

Why does the small goods/freight elevator have 3 call buttons outside rather than inside?

[@mrmattandmrchay]

People load up the lift from the bottom floor, then send it up to who-ever is going to unload it. Same from the top floors. For example if, they have lots of boxes to throw away - stuck them in the lift then send it down. Whoever is in the basement can unload them. So the answer is, for the small goods lift, people are unlikely to travel inside WITH the goods/freight so they can use the Gnd/1st/2nd floor buttons on the landings instead.

[@ag6371]

Instead of closing the towers, they should put some emergency staircases and ladders on the towers for fire regulations

[@mrmattandmrchay]

It's much more than that - You also have to factor in the cost for completely modernising the space, installation of services, toilets, whatever they put in the tower, staff to manage whatever they put in the tower. Installing extra fire exits would cost A LOT of money, for what benefit? - All the facilities are on the ground floor. You also have to consider asbestos, which also costs a lot of money to remove. For example, apparently at Forton the removal of the aspestos in the lift shafts cost MORE than the cost of modernising the lift! It's very unlikely to reopen. It it does reopen, I very much doubt the cost to do everything would be recovered (remembering that this is a 'business' to make money ;)

[@michasreisefieber]

What I don't understand is why a press on the down button allways calls the right lift and on the up button the left lift. The snse of tow lifts in a system should be to call the lift which is the nearest. All other things do not make sense. Can someone explain this strange system?

[@mrmattandmrchay]

We are talking about a lift from the 1960s here. Yes you could probably build in some kind of direction logic, but essentially you'd be adding another 50-100 odd relays to do that, depending on floors. If something went wrong with that system, you'd need someone technical to fix it! If you think about it, this is normally something which is easy to compute, on a computer! If CALL>LIFT1 and LIFT1>LIFT2 then ALLOCATETOLIFT1. Here you can work out the distance between the call and both lifts, but without a computer you're using mechanical devices to make this decision - not so easy! And with more relays, more cabinet space required there is more to go wrong. When computers came onto the scene in the 80s, this changed the design completely, until then, this was a simple system that worked that everyone understood, most importantly, the engineers.

[@michasreisefieber]

@@mrmattandmrchay Yes I understood as I watched your second video about it. It would be very interesting for me if you would compare the logic of some other lift manufacturers of that time, to see how they solved this.

[@simontay4851]

Why did they even build the top/2nd floor in the first place. The designer(s) was/were stupid to think that people would bother to go to the top floor. people just want to go in and out quick and continue the rest of their journey. What was on the top floor originally?

[@mrmattandmrchay]

I believe it was a restaurant - but it's strange that most of it is like a corridor and not one big open plan space. I suppose 1960s designers? For some history kzbin.info/www/bejne/o5K9mYWuha9mpLs
