how do you make an chain elevator

Okay, we started with just a chain bar and we are doing well, but here’s the thing, we can only stack 5 cones on a mobile goal. We already saw the 929u CAD design but we need more, if anyone could point us in the direction of a video or a link that would be great. thanks to all of you guys for the help,

Have you searched any videos of 929U’s design? He has a channel under his team name which would provide better examples of his build. I have built a version of his design if you would like any help.
