video break testing prusik cords, arborist saddle, and cobra buckle

i was especially impressed by how well a friction hitch holds on a rope and how much force a cobra buckle can take (although it was configured so the buckle couldn't slide on webbing.....which is what i think it will do first before breaking)

Need to get him to test some saddle hunting gear….lol. I know close to what was tested in video but not quite.

I’m was wanting to get him to do some saddle type dynamic falls from his new drop tower. You can hire him on his website. I wonder if there would be enough interest to raise some money to have him do it. It doesn’t need to be a YouTube video but the results would be awesome.
 
Yes, the forces here are no joke. I'd like to see a ham with a bone in it wrapped in several layers of fabric between the two ropes. This would really give us an idea how easy flesh and bone would break way before any of these ropes or buckles would go. I think we would be shocked at how easily flesh and bone would give in relation to our saddle and climbing materials.

I was worried when they were up close during some of the break tests on metal items. Really, any of the breaks, because they have metal parts and such all over the place in their setup (big metal hooks, etc) and one could blow.

They should treat these like the couple that have the hydraulic press youtube channel where they crush big glass balls and such (they have a plexiglass wall, then a camera on the experiment through the plexiglass, and then they are behind a solid wall somewhere watching and operating controls).

I don't want Murphy's Law to happen.

There was a guy that died at a construction site when a regular pocket tape measure fell from a building, bounced off the ground, and then struck his head. He was a fair distance from the building, far enough that you wouldn't expect a falling object to hit you, so he took his hard hat off.

You would think those guys would know that prusiks should be break-tested in a basket configuration.

I’d guess between 4kN and 6kN. 900 lbs or more can produce serious injuries.
 
Everyone go comment on that video for more arborist and possibly saddle hunting related tests. It’s all about likes and comments!

I bet it also has to do with how rapidly the force is applied and the area it is applied too. For instance, if my wife steps on my foot with bare feet or a high heeled shoe. There is a big difference.

Absolutely. That’s why dynamic forces are harder on rope and webbing than a slow steady static pull.
And that is why I use the nylon riggers webbing for my saddle builds instead of polyester seatbelt webbing. Every little bit of force absorption helps if a dynamic event occurs
