Hello,
your translation via Google doesn´t work correctly, so I write in English hope it´s okay 
.
Some Informatins about the Excavators are here:
There you will get help.
Thank you for your help, but I can not find any information on the site.
I would buy an excavator:
Liebherr basic 944.
What is the difference with R 944 B Basis and R 944 B Basis Zusatzhttp://www.liebherrmodelle.de/shop/index.php…sis-Zusatz.html ? There is a "Schnellwechsel system hydraulische"? or not "hydraulische" ?
I would like to add a "rotating collet"
Here is the photo:

Are there enough "fach" to "Steuerventil" for all these functions?

The "Basis Zusatz" has two more ports for hydraulic. In my opinion this should be the right for you. Maybe it is better when you write a email directly to liebherrmodelle.de
I hope this was a little help.
King regards from Switzerland

Thank you!
But I have to wait for delivery in April 2012. 
You realize the beautiful piece, congratulations!
For the 944B you do not have to do more? I would be interested.
The trailer is a self build? she is very beautiful.
