It looks like they are using twin Big CIMs to power the elevator. They look geared down just a bit (maybe 1.5:1) and spin an approximately 2" spool. A cable does all the pulling. It's amazing how quickly they drop that thing! We limited our PWM output on the down motion of our elevator to eliminate just that phenomenon...
Overall, quite a capable robot! I'm still trying to figure out how they line up to grab the tube so quickly... Nice grabber btw!
