What is it supposed to do in the animation?

Rotate, slide, pick up things and this sort of stuff. What I will have proble is hydrulic arms. Those are linked to two models and I will like them to just slide out and in when I move whole crane around.

They will hopefully give you ideas how to do what you need to do.

I did a crane very similar to that one once (hmmm, maybe I should sell it to you) , IIRC, I did the pistons with IK, pretty easy. Possibly just targeting would work too.

Getting the telescoping sections to work was tougher, and required Expressions. Basically, each subsequent section went out a percentage of its parent's extension. (I have no idea if that's how a real crane works, but it looked good.)

Parenting the HOOK to the end of the crane is fun too, since it never tilts-- it's HANGING. So you can't just parent it. I used Channel Follower, and erased the top of the "cables" using a clip map.

Oh yeah, good times. You'll have fun!

EDIT: I may have used Relativity for some of the things. Also, you can make your life easier if you set up the jacks to follow each other: then you only have to animate one jack and the other 3 deploy automatically.

I think it looks like it would be fun. I like to animate machines.

Why not just put a morph on the hydraulic pyston which will be driven by the pitch rotation of the crane? It should be really easy to control with cycler without any expressions I think.

And remember we have POSITION IK now, maybe some use can be made of that.

Hi guys!
Thank you for all help. I have read everything and on top of it I bought RebelHill rigging tutorials. Than with all this knowledge setting up the scene and objects was no more than hour. :)

...and next time will take 15 minutes tops.
