For a large wind farm installation, I'd think having a portable manufacturing setup would be more feasible.  Set it up, make the blades for the turbines, install as they come out of production, then take it apart and move on to the next site.  

If you assemble three or four of those into a makeshift helicopter, couldn’t you simply hover them to their destination?

I get this is a large, awkward load... but living in SW Va while working as armed security for the mines, some of the equipment you see transported and the lengths they go through to change infrastructure (let alone those rural mountain roads) is mind boggling...

Canada isn’t civilized?
I mean, if you have to send power long distances between generation and the city, overland is a lot easier and cheaper than underground.  You see the same logic with pipelines.

I’ve seen videos of these where the trailer wheels don’t just turn, but huge sections of wheels pivot all together, so you can swing them way out independently of the cab ahead of a sharp turn. I also knew of a guy who owned a company doing oddly large item trucking like this in the US, it’s huge money. He had the…

This is the first thing I see

We need to mainstream dirigibles as heavy transport. This is goddamn goofy and unnecessary.

Definitely the truck with trailer and that anchor/lever point. I shoot cranes with a drone in my spare time, Dad still works for the company.

Some keep the spar intact inside like a tube for the length of the blade and some have it drop the trailing edge and support just the leading, which would make it genuinely hollow. The spar is the majority of the blade by weight.

The weight they have these down to would make an F1 car designer blush.

When the blades got over 40 or 50 feet any natural product stopped being used because mass is the primary enemy of efficiency. For monsters like these even the polyester resin and fiberglass is largely supplanted by carbon fiber composites.

You're much mistaken.

Somewhere an intelligence agent is crapping his pants, poring over the latest satellite intel imagery, certain that this is some kind of intercontinental howitzer.

I wanna see how they loaded it on in the first place.

If you’re talking about the truck, absolutely cool.

This must be crazy fun around above ground power lines.

I’m going to say that the centre of gravity is much closer to where the hub will be than you expect, otherwise the forces of angular momentum on the finished turbine would be horrible.
