They rigged that wrong. There should be a twist relief at the end of the lift cable.
Reminds me of an episode of “jackass”.
I’m a terrible person. I couldn’t stop laughing at that, as it went on, and on, and on, and on, even while simultaneously sympathizing with how utterly, pants-shittingly terrifying that ride must’ve been, especially for someone already injured. I’m just the worst. 🙁
I don’t think it was related to any twist relief. More likely, it was acting more like a windmill from the downdraft of the rotors. There must have been some asymmetry in the way the person was arranged on the litter that made the thing a windmill blade.
I imagine one could build a vane of some sort that could automatically orient itself to counteract the effect.
I was trying to find a good video of the rescue of a crane operator in Kingston Ontario but nothing I can find shows the total drama. This shows the action https://www.youtube.com/watch?v=rQ6efGSW-c8 but not the horror. There was a huge fire below and the courage of the men in the helicopter was incredible.
I’m curios what dynamic was at work there. I’m thinking a twisted cable. As Marcus Ranum said, I think they had left out a pivot on the cable’s end. It looks like, at the end, the helicopter crew had decided to go find a place to land to get the hiker aboard.
Mobius,
How could they land with the stretcher spinning like that? Wouldn’t they have to find some way of stopping the rotation so that they could place it on the ground?
