I need help to spot what tehcnic sets there are in these pictures. and Thanks!

I think I have a fix for the boom movment of the excavator. I simply used the same idea as the 8851 excavator. I used rubber bands on the back of the main boom conected to a cross axel and then down to the main chassi. The rubberbands (I used two) should be fairly thight in the upmost position of the boom. I dont have any pictures now, but if you look at this picture you´ll get the idea It works a ot better now. :)
