Thanks to Lev P, who posted a very helpful comment I can reveal what the above strange VOLAT/MZKT truck is meant for...(and it had Biglorryblog guess I can tell you).
lev says: "That would be a chassis for an airfield runway sweeper/blower. The brush is attached in the middle of that frame and turns lengthwise when the truck is travelling or for parking. A large de-icer is also attached just in front of the rear axle."
And he's been extra helpful by supplying me with a terrific link to Overaasen, the Norwegian snow removal systems experts. And here are a couple of pictures from their site--click through here for a snowplough with a monster blade!.
See what I mean. Looks as if it's attached to an Oshkosh but I can't be sure....
so my guess was right. can I get a pie now?:)
