Hey Even Longer!!
I am sorry to inform you that 99% of redstone elevators do not work on meepcraft. This is because the pulse timing is different on meep than on vanilla (from what I've heard)
I've tried woolyvators and other popular designs but I know, none of them work...
Some of them did work, but they created immense lag (dropped me down to 5 fps)
Some of the simple elevators and water elevators still work (like one at the old gmall) but stairs/ladders are more efficient.
I hope that answered your question and happy meeping!!
