Crane operators do need to know a lot more than just pushing buttons. If not, cranes tip over, get blown over, and sometimes people die. I've seen it happen. Truck drivers, not so much. Although, when your truck breaks down in the middle of nowhere during a blizzard and you have a load where you get paid based on timely delivery, I'd bet having some knowledge on the truck's internals would be helpful.
