Don't read this, Paul.

Your turn...
Is it a giant Roomba for parking lots? ;D
Nope, and it's not an early Batmobile.
For this one, not the name, but the purpose is needed, and after all it won't be so hard...
for heavy loads, maybe a tractor for rockets?
A giant leafblower for airport runways?

That's an idea! But not this....
a huge runway de-icer?
Not a de-icer but your guesses are in the right direction....
It's seems to be a bit over the top to use it to get rid of a flock of birds ;)

Definetly, if you consider that in the airport where I work, they use vehicles like this:
for sport stadiums (to level off cinder tracks)?
or a huge mower?
Built for an LSR attempt?

Not a de-icer but your guesses are in the right direction....
Not for speed records...
For testing jet engines?
Not for that...
Used to launch aircraft?
That's another project behind this....
one point for you!
Another point for the actual job of this ...thing.
It won't be so hard now...
To launch the planes without a overly-long build up of speed - sort of like the catapult on aircraft carrier decks.
Yes, this was another project, but actually, this thing has been used for another purpose...
To dry pavement?
Not that, but your previous guess contains a precious element...
To catapult something - trash bags into a landfill?
Is really out there such a device?
I have no idea - that would be fun to watch, wouldn't it? :D
..and the day you don't need the catapult anymore, just remove the brakes!
Hmmm....
Could this have been used to test aircraft brakes?

Runway rubber removal?

Drag unit to get gliders in the air?

Not that....
As the tree said to the lumberjack, I'm stumped. ???
You were really there...I don't know how to give a clue without revealing too much...it is not for the aircraft brakes, but....
Aircraft engines?
Aircraft tires?
Not engines or tires...you were closer with the brakes, not fisically....
Braking parachutes?
Right direction, wrong item.
Jet engine thrust-reversers?
...all the guesses are in the correct direction, braking chutes, brakes, jet reverse...but there is another, common, device to stop a plane....
first when Otto gives up I'll post my presumption.. ;D
Technically this is always open to all and Otto will get a point for spotting the 'launching aircraft' pourpose...but I respect your decision.

Airplane arresting net?
OK, since you decide to proceed, you are really, really there. One point for the correct name of the device and the way it is tested by this vehicle.
Sorry, I did not realise Allemano was waiting for Otto.
Please disregard my answer, and I'll stay out of it for now...
This one is free for all.
Otto was really close, Allemano probably got it, you are pratically there.
One point is still there for the correct use of this vehicle.
Feel free to proceed at your discrection.

No, continue please. :)
a headwind generator, placed at the end of the runway ???
When it will be solved, 2 or 3 of you will say...that's it? was it so easy?
Read the past replies and you'll find that it's almost solved....
Testing the wing brake flaps?
Not that...someone was really close, pratically there....and from now on, only complete answers: how this vehicle is supposed to test the still unnamed braking device.
A kind of drivable "shoe" which slows down the plane while its landing gear is locked in the openings/intakes of this 'device'?
Probably pure nonsense..... ^-^
arrestor cable testing

Yes...pure. (much easier)

Well if I was close with the arrestor cable testing.
The machine would be fitted with an arrestor hook and placed at one end of a runway with the cable stretched across at the other (or about halfway down).
You would power it up and bring it up to about 120mph (normal landing speed for most aircraft) and send it down the runway.
As it catches the cable it will be bought to a stop (we hope) presumably by varying the engine power it can simulate different weights of aircraft.
Any good?
The device is called arresting gear, and it is correct, but the dynamic you wrote is not...(too expensive in case of cable failure, don't you think?)
well in that case the only other way I can see it working would be to attach it to the cable and try to pull it from its mountings on the runway. You could do this facing the 'wrong way' to give you a mile to bring it to a stop in case of a snap!
That's very clever indeed, but it doesn't work like that...
Ah - I hadn't thought of that. There's also the hook-and-wire thingy on carrier decks. Allemano, please jump in if you have it. Like that Crosley puzzle, I'm running out of ideas.

I don't have any idea either. Already made my guess which was a complete failure ;D
The remaining part is really not so hard...take a look at my 2nd pic and look how it was supposed to work in the drawing...then it's just a simple matter....
For testing braking parachutes?
gilescooperuk was right, it is a testing vehicle for the arresting gear...now the point is to find out how it is supposed to do that...it is not going to hit the cable with a hook, and a clue can be found in the drawing I posted...
Does the hook grab something on the guide rail?
Now will be a matter of time:
the pic above the drawing shows the system...it's there!
There's an arrestor hook on top of the cart.
I guess that the cart is pushed up to speed by the jet engined vehicle. After this vehicle stops pushing and brakes or makes the turn, the cart runs into to an arrestor cable.
That's it...I posted it hoping nobody notice it ...and you didn't!
Guido66 explains it very well...there are no planes involved in the arresting gear test, it is just the cart mounted in front of the vehicle that is pushed toward the cable, it can be loaded with different amount of weight, simulating different type of aircraft and if it fails, just the cart goes crash. The vehicle runs on a rail, when it reaches the correct speed, it pushes the brakes and let the cart go free.
:scratch:
Sorry I've temporarily deleted my last post (thought I suddenly had an idea...)
again:
"Maybe I'm a little lame, but I still don't understand the landing process ...
Does the plane land piggy-back on top of the speed synchronized cart?"
Now I see, it's only propelling "jets" to take off.
Obviousely not a device for decelerate planes during the landing process.
