Elevator Basics Question

Hello everyone this is my first post on the forums!
So I’ve noticed the design for the elevator.

[ATTACH]8601[/ATTACH]

Now I’m not sure about something. You see where the pink arrows are pointing,
are the sprockets located there allowed to spin freely on the the drive shaft?

I have noticed that leaving every sprockets on the lift to spin freely has no effect at lifting it. Just spinning chain.

But I have also tried keeping both sprockets ( pink arrows pointing) completely stationary ( with lock bars) , no spinning at all.

This works only for the first section, I have tried the second but the lift would constantly get stuck because of that first section sprocket.

I have also tried a variation of making sprocket one immobile and two free and vice versa to no avail.

I have seen many lifts with 3 sections but my lift is expected to have more.

Also btw do I keep the sprockets ( green arrows) spinning freely or do something else?

All suggestions welcome!

Sorry about this but this is my first time making this type of lift.
Thank You

You need to attach the chain to the lift at the topmost tier - that is, the chain needs to be screwed onto the lift. If you don’t do this, the chain will just run through the sprockets as you noticed. The sprockets do need to free spinning.

So does the chain have to be directly attached to the metal?

And EVERY sprocket spins freely right?

Yes.

Yes.

From your picture:
The continuous elevator lift basically compresses the distance of the sprockets and feeds the “free” chain back up the lift through the yellow chain. To lower, you decompress the distance by taking away from the yellow chain. Note that the yellow chain and red chain are one continuous loop, but were divided for coloring purposes.

Thank You very much now it makes more sense! :slight_smile:

Time to repost this (3 year old) link I guess.
