Demining arm attachment

This was done when I was still using AutoDesk Inventor which I have now converted to SolidWorks 2009. It is an attachment that is fitted to a standard truck type crane, sliding into the end of the crane. The fork and ripper explain themselves; the disk roller is for setting off anti personal mines under obstacles. You can see the independent disk move up and down independently on a very large ID. This equipment has been used all over the world and is now in many differing forms. I think the rollers in combination with the Casper running on steel wheels set off well over 1000000 mines just in Africa.
