If you searched for "bloopers" or "outtakes" then the first 15 seconds is for you!

THIS VIDEO EXPLAINS HOW THE LOGIC CIRCUITS WORK ON AN OTIS CARRIAGE SELECTOR. Facinating piece of machinery, although it's not too complicated to understand and I've done my best to explain it so that even beginners can understand it.

If you're interest in relays, then this is for YOU! If you're interest in relays AND Elevators, oh man, this might be too much for you lol!!!!

This is the "EPIC SELECTA MOVIE PART 2" that I mentioned in my previous video. I suggest you see PART 1 first as it gives a bit of background to what this unit does:


The BIT NEAR THE END about how the elevator "decides which way to travel" is more or less the same on ANY relay controlled elevator - it's just different parts are used to achieve the same result. I hope to upload how the Express Lifts design works at some stage (see the end of video for a quick look at what's to come!)

Thanks to Greg for allowing me to use his Otis machine room movie:

Good quality movie this one in a well-kept clean 1970s motor room - give it some more views please as I think it's not been "discovered" yet by some of you elevator enthusiasts :)

MOVIE INFO: This movie has taken the longest to make out of all my movies. 6 months ago I started drawing the selector in adobe photoshop and 6 months later after making the animations, video content, images, titles, voiceovers, etc, it's finally uploaded! (thank goodness for that, as this one has been holding up everything else!!! I've got requests coming out of monitor I guess!)
