Why not use a worm drive? We used an Andymark Wormbox in 2011 for our elevator with decent success (we had other racking problems irrelevant of the gearbox) and the RAW Box, as already suggested, could work. We actually used a custom worm drive last year to winch back a really heavily loaded catapult arm, but if you don't have resources to custom build, use a COTS worm gearbox. You can mate with a CIM and get a ton of power out of a reliable box.
