I have forgotten to talk about my first loader : a pneumatic wheel loader, with steering and pneumatic arm.

This loader is equiped with Power Function System. A XL drives the wheels with 3 differentials (front, rear and center). A M operates the steering (worm gear on 40t). The pneumatic arm has 3 pneumatic cylinders, two for lifting and one for tilting. Tilting configuration is a parallelogram configuration (pulling work). The pressure is given with a external hand-pump, that is why there are 4 plugs on the left.
