Simple lift with 2 motors

Our B team is trying to make a high lift with 2 (maximum 3) motors. This is our second year in VEX, so they don’t want to build anything that’s too complicated e.g. a ratchet. They even were hesitant at the idea of a four bar. Any ideas?

Did you see 6461Z at state? He only used 2

I saw the lift, but not up close. I’m not really sure how it works, either.

It is like this video. Unlike the video 6461z’s is powerd by the rack gear on the linear slide. Pulley rope works well too.
