Woah, larrylee, I bet that is a Demag CC series crawler crane?
Exact model I not sure, do enlighten me...
Ah yes, the counterweights are adjustable, the weight may seem a
certain amount, but when come to 'counter' the weight, nia, the
crane still depends heavily on its outriggers (the little things
that stick out).
Regarding the Siku crane, I also have one, yeah, the counterweights
are not removable, I find it quite pain to do and cannot lift heavy
things; the crane tends to topple easily!
I have only got in touch with collector grade crane models
recently, about three weeks ago. It took several sleepless nights
to decide whether to buy or not!
I am heading for the Demag AC500-2 with luffing fly jib as the next
crane, requiring a total bill of 900-1100 SGD!
Now that is really expensive...!
