A 15-tooth sprocket on this axle drives a 32-tooth sprocket on the lift axle, (now down to 18:1) and 15-tooth sprockets all around on the lift chain. Theoretical lift at 40A (before losses) is 125 lb.

We're planning more of a pawl than a brake - it'll be up to the motor to bring the load to a stop. We'll probably going to use a 1/2" ratchet wrench on the gearbox shaft and use a servo to move the toggle back and forth. If that's too finicky, we have several brake designs to choose from.
