Here is the large actuator I designed awhile ago.  I dont know if it will be helpful for you. 

So, new changes are ready:
The last time the front part was empty inside, there was only a frame. Now all the mechanisms are installed and ready for connection with the rear part. Also added a few external decorative parts. I could not make the front bumper like the original, which I would have liked. So while I changed it. Probably in the future I will change it.

And a few photos of the inside:

Starting the second half 

 

 

Those weird angles in chassis will cause problems. Friction and similiar things will appear, have you tried straight frame, like this one?

I tried to repeat the outline of the original:

Only external elements are fastened at such angles. All parts of gears and shafts are connected at a 90 degree angle. I already connected the motor, everything works correctly. But if something goes wrong, of course I will fix it.

But what I worry about now - is the remaining amount of red parts)

Assassin,

Tout dabord bonjour à toi. Cela fait maintenant plusieurs jours que j'essai de reproduire une chargeuse forestière en lego et je viens de tombé sur ton impressionnant moc. Je le trouves sublimes et tellement proche de la réalité que j'aimerai m'en inspiré pour faire le miens si tu n'y vois pas d'inconvénients. Si tu es d'accord penses qu'il serait possible de mettre quelques photos supplémentaires au vu du montage complexe que tu as du accomplir, c'est en outre difficile a reproduire avec une photo.

Avec l'espérance que tu puisse me repondre favorablement, une bonne continuation a toi.
