Yep, this gearbox gives us a reduction of about 12:1 to drive (on 6'' performance wheels) and about 16:1 to the climber. One gearbox and lifter arm were able to lift 70+ lbs in our testing.
In case anyone was wondering, we chose to go with 4 rather than 6 cims for the PTO because math told us we could, and cims are always useful for other mechanisms.
