swivel loading

Bart_ said:
Anybody put a few finger in the wind figures on loading? Ie is it at 5% of rated perhaps guessing? Isn't rated also yet again lower than breaking?

I agree, to a point.

Seems like most ratings are given as WLL or MBS. Swivel rating is probably MBS, but that's with no side loading.

Side loading may significantly affect the MBS and routine side loading may accelerate wear, but I can't say with certainty.

I ended up switching to a camp gyro 3. Three climbs in I'm absolutely loving it. Almost like having a second bridge.
 
Ok here's some numbers assuming the model. 36 kN MBS (8093 lbs) and 5 kN WWL (1124 lbs). Half of a 200 lb guy is about 10% WWL and 100 lbs/8093 lbs is 1.2%. If you drop and stop call it say 3 G's you triple those numbers. The numbers are small but the wild card is no specified allowed bending loading of the pivot axle. It is actually disallowed in the spec sheet as in the case of the swivel being against a rock (branch). That said, if you can keep the axle bending low say as much as created by the biners and ropes skidding around the arc of the "ring" during self alignment to the loading vectors you're probably ok. But if a biner starts jamming and levering against the central swivel body I suggest that's the same as the disallowed loading. The photo shows the hitch biner right at the verge of starting to do this levering. That said, the swivel isn't made of egg shells and can probably stand quite a lot of of axle bending force - but how much? Question marks are bad juju in life support situations in my opinion.

So I vote no, you shouldn't configure like that. Sorry to be a bummer :) I suspect other swivels are subject to the same restriction.

Everything looking new and shiny and clusterfuckish. Clean that up. Hell no. No. what in heaven's is that tachyon termination, tape homemade kiddie stitch madness. you see others using that rubbish too. Do not follow the multitudes of clowns on youtube. Dangerous practice. Climb safe please.

It's a piece of tape to keep the termination tail out of the way. Yes I have a fair bit of gear that is newer in this pic. I've been an Arborist for over a decade but transitioned to consulting and treatments after a few years of climbing. I've been having fun rec climbing lately, venturing away from my Blake's hitch days although I definitely still use it. Playing with different systems and configurations brings me joy, i never felt I had the time when it was my job. I'm just giving an example of configurations to allow some open discussion. I embrace well thought out criticism but wish we could be nicer to each other. This is a passion of mine and like feeling proud of our community. Thank you everyone for your input

That’s just the way islandarb talks, he’s got your best interests at heart.
 
Maybe I'm missing something but there is a third attachment point on the hitchclimber which works perfect to attach a second system to.... allowing a single attachment to the swivel or bridge. Move the termination of the primary system to the top hole and attach the second system to the middle.

That is an option in that example but it would increase the likelihood of hitch getting bumped and isn't as clean imo. DMM and others have basically said it's fine as long as the angle isn't so tight that it's bumping into the swivel causing some side loading. Either way probably best not to make it a habit. I'm not really looking for other solutions, primarily was just looking for discussion on this configuration which I think is pretty thorough by this point. I ended up getting a camp gyro 3 which is awesome and allows for so many different options.

I believe that is a scaffold knot, and the tail was wrapped with electrical tape for some unknown reason. I don’t think it’s a sewn eye.

OP said to keep termination tail out off the way.

@Winchman I consider a scaffold knot to be an absolutely essential knot to know! Maybe because it’s the first thing I was shown.

Man oh man, that little bit of electrical tape on that tail has really got a lot of panties in a twist.......

I call it a double fisherman's loop but it's more technically a scaffold knot.

Seriously lol, thanks I'm kind of over addressing it at this point.

Fuck de electrical tape....but man I hate knots on any terminations in my climb lines or lanyards.....and I truly hate tachyon bungee cord....but brohammer up in SoCal seems to dig it all.... bless him. But I only climb SRT so nearly all my lines have no splices. Crane work ones do..... Horses for coarses though... Power to SoSal man...

To each their own right? It's a 12 foot lanyard so stretch isn't a big factor. Just a pice of rope I had around and figured I'd get some use out of it, an eye would be preferable though.. I enjoy moving and stationary systems, they both have their place and I like to go back and forth. Mostly srt these days though. Thank you for your blessings.
