This is a surprising model from Lego. It is the first time I have seen a Lego vehicle that can fit two mini figures side-by-side. In my opinion it is largely based on the Liebherr LTM1300/1 and I am in the process of making it look more like it. The first step was to remove the articulation. It was probably designed that way to make it easier to assemble (as well as making it slightly steerable) but I have not seen any cranes like that! I have also lengthened the extending boom by a third.
After I lengthened the boom
Err... testing the boom
The top needed a tweak too
De-articulated with a bonus storage area
I made some further mods after these photos, but I didn't take any photos, and it's too late now as it has been recycled! However for all it's flaws I've been missing this model... and I think the parts are currently un-used.
