There she is. She isn't done yet, but she's close.
The lift is a three stage, chain driven, closed loop system made with extruded aluminum (with a little help from some surgical tubing). The fork has arms that rotate in opposite directions, powered by a globe motor.
We never actually measured how high she can reach, but you can get an idea from the picture.
We didn't have time to perform any serious testing before we had to ship. Hope she works.
