Awesome video. But hopefully, you can clarify something for me. In the video on the high line section, you kept your MA on the lower reeve system and your backup to the carriage. Wouldn't that make you (the rescuer) the mid link if the lower reeve (red line) failed. I hope that makes sense. Again awesome video and thank you for putting this out.
Why do you use a fixed length backup versus an adjustable (like a Connect Adjust)? It is for the simplicity that a fixed length provides? Excellent video
Thanks, Yes mainly to just throw in a bit of simplicity, but any adjustable lanyard will work as well, & will probably work better. But these fixed lanyards have a nice length, light enough, & packable enough to fit into a bag along w/ the carriage & reeving assemblies.
Why do you use two rings in the delta quicklink? Higher up in the chain it's all connected through a single ring anyways. And I was recently looking through the manuals for quicklinks, and apparently they recommend using a torque wrench to tighten the gate (same for the screws in the rings I thinks), do you carry one on the truck? Or is a regular wrench/finger tight good enough for you?
Two rings are a permanent part of the head bridle of the litter & intended for redundancy & strength when using the litter in other applications, for example on a basic steep angle orientation where the entire load is supported using only the head bridle, and you have 3x litter tenders plus a patient (I have another video on that). In the applications shown in this video you don’t necessarily need two rings & could just let one of them hang, but that could possibly confuse people even further. Plus if the litter bridle needs to be rigged in a super low-profile way, then the internal bridle catenary angle increases which can exponentially amplify the forces seen within the bridle components. The OSHA & SPRAT answer on the screw links is yes you should tighten the links down with a wrench to torque specs…. but let’s be real; professional rescuers in a dynamic environment should be more concerned with the amount of stuff they have to carry around, the weight of it all, & the ability to easily make connections & disconnections on the fly quickly. The only time & place I have ever exercised the practice of using a wrench to tighten a screw-link was during a formal SPRAT certification course.

That’s why there are ASAPs on both sides of the reeve line at the package
@@Propeller_Headoh yes of course. Thank you!
very nice

are those petzl plates only held together by the lashing on top?
No. There are 5 permanent gold rings on the bottom that also keep the Reeves paired together
