Tracing back the URL of that pic and you find a few more
These pics I'm guessing are from a 2003 truck trial. Helgeth I beleave is the sponsor/builder? of this rig. Uniknicks seem to articulate something like a skid steer and/or US Marine Corp Gamma Goat (may not be exact name but it is something like that).
They have no steering axles - all steering is done with the articulated link in the center. They have a built in double drum winch and that blade in the rear is what gets dropped and pulled against. (Looks like the trial truck's winch has been removed)
I think one of these would be the start of a killer Moab, UT extreme recovery service !
There's one here in W Illinois that I've kicked the tires on - very cool...
