I first learnt about this tech via an advertisement type article. This article mentioned 65 degrees. However I thought it not appropriate to post a advertisement type article to Hacker news. The article I posted was found via Google of the words ... Blade lifters to transport wind turbine blades ... https://www.google.com/search?q=Blade+lifters+to+transport+w...

FYI this is the link to the advert type artical / press release.

It mentions 65 degrees ..... https://www.imnovation-hub.com/energy/blade-lifter-wind-turb... Quote " The blade is secured to a hydraulic system that can adjust its orientation up to about 65 degrees, and some models can reach 90 degrees. This allows the blade to avoid obstacles and reduces the need for large trailers. Additionally, the platform where each blade is mounted can, in some cases, rotate 180 degrees to counteract wind gusts. Some models can lift up to 1,000 metric tons. "
