A Crane at Work

Probably not much of a story here with this small snapshot print, but who doesn't love an old crane, and besides, it is always fun to take an every-day scene from long ago and blow it up and look at the details. Here a crew uses a wonderful old crane.

I'm guessing that this is a gravel crusher setup that they're assembling (or are they disassembling it?).

So what's that guy doing under there (in the crop below)?
