Rotisserie - never seen one like this before

While surfing the net I came across some pics of a Cuda on some sort of rotisserie flipped up on its side. What caught my attention was that it wasn't your "traditional" rotisserie that bolts to the subframe at the bumper mounts. I'm not really sure how this thing works as I have never seen one like it before. But it does look like it could be more convenient to use in a space limited garage than it's bigger cousin the bumper mounted rotisserie. I'm intrigued and want to find out more about it. I tried a search of the net to try and find out more about it but came up with nothing. Has anyone ever seen one like this one?
