We used home made versions of what you linked above on our bot last year to lift the totes. It worked alright but wasn't great. The issue we found with them is if we jammed our mechanism, it would cause of few of the attachment links to break off (they're a master link with a flange on either side basically). If you broke your chain properly (not using an insane amount of master-links) it might be feasible. Might need to do some load testing though.

What we found works really well on the other hand though is just passing bolts through the holes in the chain and bolting it to the mechanism we are moving. As long as you aren't needing to have the chain loop around the sprocket, this method is clean and easy to implement.
