Here's a small scale mobile crane loosely based on the Liebherr LTM 11200. Not all of the details were implemented due to scale, since I wanted it to be functional and detailed. There was also a little bit of cheating with the counter-weight being a slab of steel taped on (it would've taken too many of bricks otherwise). The images don't seem to be embedding so links will have to do for now.
Here it is with luffing jib and super-lift.
