Looks kind of like a boom point sheave for an electric shovel.

Sheave's are usually grooved more like this for the wire rope, hard to tell in that picture. Our sheaves were always symmetrical. Also general D to d (sheave diameter to rope diameter) would be 18:1 so that's hugely over sized for what it would need to be, doesn't mean it wouldn't be oversized for another reason.

I'm leaning more towards something like this

It could be either one they both run cable, Depending on the size of the shovel the cable size isn't all that different than that ski lifts cable...

We had 3 different size electric shovels at Thompson Creek and the smallest one had saller point sheaves than what's on that truck..

And yes it's hard to tell what the actual shape is at the angle of the pics

Smoke is from those damned Canadians, which hasn't been too bad lately
This is just the local bipolar weather, rained like hell yesterday
We got socked in for 5 days until this latest round of storms came through, I can only imagine how bad it hit you...
 
This series is from a test of a MK-48 Advanced Capability Torpedo test (circa 1999). It is just not the same as punching holes in ships like all the WW-II movies I grew up on! The torpedo does not actually hit the side of the ship but explodes underneath it and rips it in half.

You going to Phantom Ranch?

Yes, but just 'passing thru'. South rim to Phantom Ranch and back up (South Kaibab trail to Phantom Ranch and up the Bright Angel back to the south rim). I do rim to rim with a group of friends Memorial Day weekend every year. The north rim hasn't opened up yet this year due to snow and rock slide damage (closes from 10/15 - 5/15 due to its remoteness, snow, access, etc.), and it's too hot to hike across the bottom after May, so we did an abbreviated 'rim to river to rim' hike this year.
