We were just stuck on the math. It was just hard coming up with ratios. Thank you for all your help.
@rahilm: highly curious, what overall reduction did you guys go with?

We use a PTO system, meaning we're using all 4 of our drivetrain CIMs to power the hanger. The overall reduction we went with is 400:1, which includes the drive transmissions, and additional gearbox joining both sides of the drive, and then a final reduction through chain. We're looking at a lift time of ~2 seconds.
I think I should mention that our hanging system is closer to 254 than 1114 in design in that we are using a chain drive hooked up to the arm doing the lifting, instead of using a winch like 1114 does.
