Introduction: K'NEX Mobile Crane Truck

About: I don't always make instructables, but when I do, I prefer to use pictures. Stay instructed, my friends.
Taken the Imperar Supercar to the next level, a crane truck. Feedback would be awesome, especially on how to create a pneumatic/hydraulic K'NEX structure.

Features:
-Steering can be done on the left-hand or right-hand driver's side.
-2-section boom crane with counterweight.

New notes:
-No, the large gears are not connected to any motor, nor are they connected to any other gears.
-The boom is actually quite flimsy and will not stand on its own. There are also no outriggers.
-1524 pieces were used; total mass approx. 8 lb_m (3.6 kg)
