An old machine

Near my home I found an old wheeled Liebherr 900.
I decided to give it a new life.

Equiped by RCX, and supported from air by my Atlas compressor, main function
on this model are:

1) Steering-Tower rotation combined, controlled by the same motor

2) Traction and outrigger controlled by the same motor selecting by a
standard technic switch

3) Two sincrinized pneumatic valves controlled by the same motor, and a
third controlled during tower rotation.
