Are hard hats required for overhead crane use?

Yes

The rule of thumb is that you should always wear a hard hat, if there is any possibility of something falling onto your head, or of you hitting your head.

That pretty much means that we put on our hard hats when we get out of the van and take it off when getting back in the van
