Not thinking wrong, that's why fall distance is an important part of the shock load equation. But so is the force of the stop. A more gradual stop equals less shock load. The question wasn't, "will there be a shock load on a safety cable," but, "how is shock load calculated?"
correction: *stopping* after falling.I tend to agree -
for example: 12 pounds falling 1 foot is 24 pounds of force, whereas 12 pounds falling 6 feet is 84 pounds of force. (more or less)
Or a Maillon Rapide. A great alternative and very secure.
I had to look that up (and not just because you spelt it wrong).Or a Mallion Rapide. A great alternative and very secure.
Stopping distance small = more shockload?
So double wrapping a safety on moving lights to decrease fall distance is incorrect. ?
No matter what you call them they have a rating which is MBS not WLL or SWL. As long as they are done up correctly they are good but must be used as designed.I had to look that up (and not just because you spelt it wrong).
Maillon Rapide
Here in the US, we'd call that a quick-link, and endlessly debate its appropriateness.

Good thought but I'd find it a little impractical to inspect and see at distance - like mousing can be seen - and if it bounced or the safety cable loop is rolled/rotated the link would be upside down.Also note that this is also why you should ALWAYS face them so that they "close with gravity" this way you help prevent them vibrating completely open.
And GAC-Flex Slings? Anyone care to veer down that road??Good thought but I'd find it a little impractical to inspect and see at distance - like mousing can be seen - and if it bounced or the safety cable loop is rolled/rotated the link would be upside down.
I'm in a minority on the safety cable on lights - I don't loop through yoke but cinch around the eye on the fixture (or around the pipe) and clip to itself (or to the eye). The yoke to pipe doesn't protect from what I think is the most common failure point - the yoke bolt. And IIRC the mouse requires all accessories - color frames, top hats, etc. -to also be saftied. I've only ever seen a barn door fall. YMMV
1/16"gac has a breaking strength of 480 pounds so 60 SWL if the swages and hook are rated for 100%? Put two on movers.
Since we're veering down the path to the tightening of Quick-Links / Maillion Rapides; an area amateur group, a group where many of the performers were teachers, from kindergarten through colleges to universities and (in their minds) beyond with the bulk of their builders, sound and lighting members being their students; many afflicted with SEVERE Queen / King Of THE Booth syndrome:
