Elevated lift system

[fayman4ton]

Hey guys, Im with 2854. We are developing an elevated lift system similar to 254's and 1086's 2007 robot. Can someone explain or draw out the chain system so the 3 piece ladder system can be raised with ONE closed loop chain. Apparently it's too difficult to use 3 separate chain systems per frame because I don't know how to position the timing belt clamps in the correct positions. Can someone help me please? Pictures (or videos) would be very much appreciated.

You can see the geometry in these two pictures:

The belt or chain is fixed to the lowest moving stage of the device. You can see the clamp as a small vertical piece directly on the belt path. The driven pulley is in the bottom right of the second image.
