I'm curious to learn if there have been any studies or tests on the use of climbing rings in sideloaded configurations. Rings are commonly referred to as 'unidirectional', but of course this only applies to a 360 degree radius along the major axis. We are now regularly loading these rings along the minor axis, in effect moving from a 'pull' (proper orientation) to a 'bend' (crossloading). Its very likely the forces are negligible given the mostly low, static loads exerted in these applications. But it's worth noting that a onetime well known, hazardous use of gear is now commonplace and excepted(?), at least in these configurations. Ie: "Don't ever side load gear. Except these rings, that's totally cool." All I'm wondering is where is the testing? I side load rings all the time. Redirects, canopy anchors, 3:1 systems, lanyard cinches. It really doesn't seem like a big deal until I start thinking about the potential forces. Spiking a rope like this is completely sideloading: Maybe even in two different directions ?? Granted it's a very short length of ring. Virtually no leverage generated. But still worth considering. And what about the biner? Using a biner like this isn't a major axis load anymore. It's something else now. The biner can be oriented along the major axis but it's not seeing that force anymore. Only one end is loaded. Arguably crossloaded. How are these uses any different from the stated warnings? (hazards we've been careful to avoid for decades): The difference must be in the linear length of sideloading. Is a 2" section (of ring or biner) that much better than 4" carabiner? In this setup both the ring and the biner are (maybe?) side loaded. Each one a good 45-90 degrees off its proper intended use. I'm not condemning here. In fact I'd be very disappointed to have to do without these tricks. To me they're most of the fun of SRT. But even in the likely case that I'm over analyzing here it is important to clearly distinguish what is and isn't 'ok' in the cross loading of gear. People new to the industry may not learn the subtle differences here, or the respective hazards. More importantly, where is the literature? Is there any? I can't find any companies showing this as acceptable use? (Actually I think the ART snake anchor literature shows a ring used like this) Looking for some dialogue here. I don't know where the practice came from (mountaineering probably?) but I do recognize that it is fairly new to the arborist world. Maybe learning what industry it originates from would help to track down any available info. Another point: Often times, depending on the rings, I'll get burrs from the captured biner rubbing against it. Now there is a concern for running rope as well. The SMC rings seem especially bad for this.
