Pneumatic Crane

I had to have a bigger crane than Lego!

This model is 32 inches long from the end
of the boom to the back of the truck. The
boom itself is 28 1/2 inches long closed,
and 48 1/2 inches long full extension.

The pneumatic system uses 2 air tanks, 1
pump and 4 pistons.

The truck has 8 wheel steering, 4 synchronized
outriggers, a V6 model style engine with
opening engine lid and a toolbox. The crane
extends with a manual hand crank and the
hook is attached to a spool that works
in the same fashion.
