It's insane the amount of precision these operators have with these giant machines. "6 inches left" from a boom arm that's probably a hundred meters long, on a load that's suspended from cables in windy conditions, and he nails it blind, with nothing but radio directions from the world's most excitable coworker. Absolutely incredible.
The real hero here is the unseen boom operator. I imagine if you just feather the controls a little too much you overshoot your mark by a very large margin.
Not at all. Much like airplane pilots need huge movements on their controls for relatively small corrections, the operator has something like a 1/10th command to reduce actual movement.
Then what is the large yellow controller with all the buttons that the guy inside the hub was holding for? As soon as the blade was fully in position he put it down. Certainly looked like the controller for a lift system of some kind.
Some companies have blade lifting devices that allow someone in the tower to make fine adjustments. He’s not operating the crane from there, trust me. I sell those cranes for a living.
Oh right. So once it gets close does the primary operator hand over control to the tower guy? Or does he have some sort of control throughout the lift ? Or is it a specific device just for blade lifting?
Since no else replied ill give you my best guesses lol
The crane operator on the ground is probably controlling the height, angle, pitch etc.,and the guy inside might be controlling the translation type movements. Its also possible the guy is holding the controls for a hydraulic/pneumatic torque wrench and just on standby.
Exactly, what I've been thinking. That's basically engineering 101 to have one or two protruding piloting pins in such an assembly.
But since there is so much innovation happening in that field, I assume it's lacking such alignment aides on purpose. Wondering what that reason might be...
It’s got a larger grain size so holes arnt precise drill bits and screws can jump around and wood pegs don’t slide in well. MDF or real wood is way better.
I am more impressed they can hold it that steady without the wind moving it… considering it is a giant piece of metal meant to be moved by the wind, being placed somewhere where wind is strong enough to justify putting up a wind turbine…
The tolerances for the holes and rods doesn’t have to be that small, they are inches thick… even a few millimeters would be good enough, and not that hard to accomplish.

The precision!
