Re: Vertical Tracks for Forklift

We wanted to not rely on Vexpro or Andymark for the elevator parts, and made our own system using only mcmcastercarr parts.

It rides on a 2x1 tube and uses UHMW rollers and plates.
It is very smooth and very easy to slide and has no wiggle.
We should be powering it this weekend.

As for reductions we are using a cim going to a 10:1 planetary gearbox, then a 6.5:1 reduction using the single stage clamping gearbox from vex. We are having two of these that share a shaft, so 2 cims going through a 65:1 overall reduction.

We are going to see the system and determine if we need a brake.
