OLD LIFT CONTROL CABINET - and what is the mystery motor? 

Standard in Sweden as well and some households still have them. That little end cap wasn't (Isn't?) plastic but metal and painted in a colour matching the current like 4 amps or 6 the fuse would pass. Also, the "bottle neck" came in at least two different sizes depending on the current. You couldn't put a 20A fuse in a 6A slot. It would be too big even though the bottle was the same size. Fuses filled with fine sand to prevent plasma discharge.

@@daicekube The system is called Diazed, a terrible German acronym for "Diametral abgestufter, zweiteiliger Edison-Schraubstöpsel", which loosely translates into "diametre-coded two-piece Edison screw plug" and was invented by Siemens in 1909. It spread quickly across most of continental Europe except France and Belgium because it was considerably more practical than most other systems in use at that time. Technically they're cartridge fuses, not rewireable like the old Wylex ones in the UK. There are six sizes, DI to DV plus the additional DL invented after WWII in eastern Germany. DII (2-25 amps) and DIII (35-63 amps) are by far the most common types, DIV (80-100 amp I think) and DV (up to 200 amps) are quite rare and DI I've only ever seen in Ireland. The smaller sizes (DII and DIII) use Edison screw bases, the larger ones are imperial Whitworth threads. Expect for sizes 6 amps and smaller, the tip diametre corresponds to the fuse size so it's impossible to use larger fuses than intended by the manufacturer, that's the "diametre-coded" part of the name. Each size has a unique colour seen both on the indicator and the key screw in the base. 2 amp = pink, 4 amp = brown, 6 amp = green, 10 amp = red, 16 amp = grey, 20 amp = blue, 25 amp = yellow, etc. These fuses were reasonably popular until they were all but replaced by MCBs in most applications. In the 1960s Siemens developed the smaller Neozed or D0 system, which only goes up to 63 amps. D0 fuses are still fairly common as main fuses in various places. Perhaps the biggest advantage of bottle fuses over rewirable fuses is that they can be unscrewed under load and even replaced with a short present without too much risk of injury. I've shorted Neozed fuses dead across two phases (pinched wire in a consumer unit) and didn't hear as much as a pop when they went.

I'm sure he'll be very happy with this comment! I've known Harri since he was about 12 years old! A long long time ago!

@@mrmattandmrchay Yeah! Hard to believe how long ago that was now. I do miss his videos a lot, they were a staple of the beginning of my interest in Elevators. Yours and his. Always thought it was interesting to see the difference in Elevators in North America and here.

Cool... glad you like them and thanks

cool, thanks! Glad you like them :)

Thank you very much!

It's just a reverse phase relay - it's a 3-phase motor designed to survive being stalled, and it's holding the switch down. If any of the 3 incoming power phases are lost or the rotation is wrong, the motor lets go of the switch and the whole thing stops. Rather common things but they don't normally look quite like that.

Cool, thanks Luke!

mrmattandmrchay No problem!

The motor, in the panel I think is to detect phase reversal Robert Gibson ex ECM LIFT MAKERS

@@robertgibson8820 Yes he said that.

Yeah... just got in the ""if it doesn't end then I'd feel bad about ending it myself" and a split second later it ended!

Interesting, thanks. Very difficult to work out what those relays do, without some kind of chart!

@@mrmattandmrchay I practically grew up with the systems and had many of those where I started at schindler. The troubleshooting of the systems was a big challenge for me at the time, but I was always happy when I found the error :)

Yep, you agree with me then ;) Must be something on top of the lift car which we haven't seen

oh yes!! I think I've seen a video (can't remember who uploaded it now) where I think they show this mechanical device. The whole thing rotates and operates what looks like a piston (or the piston does the rotating - can't remember). But basically the whole thing does a rotation then resets. Wish I could find it again.

thanks! I realised this only after the video :) Thanks for the info

Great guess, but not right! See video uploading tomorrow!

I’d say it’s because of the direction of travel. If the lift is empty, when it goes up it will be much easier for the lift to start because of the counterweight helping to pull it up. When the lift is empty and is going down, the motor is using its energy to lift the counterweight which makes it struggle a bit. You can see in those 2 clips that the selector wheel is spinning in the opposite direction. :-)
