Tilting at…
@rickcogley What do you mean, on their base?
@rickcogley Ah! No. These are the old kinds. They were built to face the usual direction of the wind.
@pratik First off all, lovely picture. And also great discovery in the comments. I wouldn’t have noticed it, but as soon as you zoom in, you can see the rotating platform. Which I still wouldn’t have noticed except that it looks so similar to another design I know. I grew up in and around forestry, and one of the machines (Valmet 911C and 911.3) has a cab that sits on a large tilting, hydraulically controlled slew ring, so that it can rotate with the boom and remain level on any terrain.
