Dooes anyone know what this crane does?

The picture of a pole truck is just that. you have a auger for digging the hole and the clamp tongs to pick and place the pole. Sometimes there will be a fiberglass basket attached to the clamp to raise a man in the basket. Most jobs have separate bucket trucks just for 1 or 2 men.

I'll agree with that statement.

I may have to chase down the guy selling it to ask him what is does.

Not much to add but very interested in this post. Curious that it seems to have X-Y translation at the base which implies precision movements. Maybe used for setting big metal power line supports?

Whatever it is, it appears to only be able to operate in the straight up vertical position. Those lift cylinders are not large enough to support much of a load other than the weight of the boom itself.

It looks like there's a large pin hole to lock it in the vertical position.

I've seen something similar at a ski resort setting towers for ski lifts.

I think that may be what it is for.
