Swivel

Hitch climber pulley with quickie attaches to swivel and then carabiner to d’s. After using it like this yesterday. I’m going to just use the quickie and carabiner, that keeps the lanyard I. The right position
 
I don't understand exactly how the swivel is being used for a lanyard. Here are a couple of swivels can be used for lanyards

I have the quickie through the hc and carabiner through that. I found that to be to much too. So now after my climb yesterday I’m just using a carabiner again. I’ll find a use for this swivel somewhere. Maybe a tire swing.. lol

Being a machinist most of my life, I tend to look at anything like these swivels with x-ray vision. Most of them have a surprisingly slender inner shaft. They look very beefy on the outside but the actual spindle between the two halves is not all that big. On the ZigZag, for instance, you can see this since the spindle is exposed and not encircled with bearings or housing. Also, the halves of the swivels are often just held together with a rather small cross pin. Now, I don't mean to sound like I am casting doubt on the load ratings. I am sure these are thoroughly tested, at least by the reputable, better known companies. It is simply a personal feeling of misgiving I have, from my own life basically depending on my various gear. I remember noticing how skinny the spindle on the ZigZag swivel was and I simply could not bring myself to hang from it at any considerable height! I bypass it with a biner through the hole beside it and just forget the swivel. With my other swivels, I use a safety strap, a short webbing sling, rigged past it which would catch me if the swivel let go. I can still spin quite a bit on the swivel since this strap is not tight, but it would catch me before I dropped more than a foot or so. I confess some of my concern stems from me simply being quite a bit heavier than I was when younger. I weigh about 185 now instead of the 140 pounds I was most of my life, and I can certainly feel the unpleasant difference when climbing. And I think we tend to get more cautious as we approach our elder years, taking less risks, more mindful of our mortality. Anyway, the internal neck of these swivels just seems to me like a weak link in the overall chain of a climbing system, but I am perfectly happy to be proved wrong.

I'm a machinist too. With the correct materials, structurally engineered and loaded correctly. The cross section for a SWL in our applications is tiny. I get way more freaked out by the fact that we work with tools that can cut a loaded rope with the lightest of touches. Or that every climb I have to inspect, test and trust every aspect of the tree.

My mental calmness comes from this logic. Most situations and climbing systems normally have some give, testing I have seen on youtube. Shows that there is some creep around peak 1500 lbs of loading, worst case lab style testing. Add in rope stretch and tree deflection. Then think about everything is rated above ~4000lbs min failure. That most times the max load is right around your weight. If any climbing system fails due to loading something very very bad has happened.

Now cyclic loading causing fatigue, when not used properly. Or long term wear. Can cause me some doubt, but regular inspections and timing out gear is a pratical way to negate this.

I'd love to see someone do a pull test on one of these swivels. Not that I would buy one for life support. The money difference is so inconsequential. I just love seeing gear get tested.
