> Mooney was told his crane didn’t have to go through the long approval process required for newly designed large cranes and that it could be approved as a mobile crane.

There has to be some kind of miscommunication going on here. By what definition is his crane mobile? Because it's easier to disassemble and load on to a truck than a tower crane? While the DoB's classifications for cranes seems arbitrary, I can't say I blame them for not considering it mobile.
