Tripod Rigging Options for Confined Space Rescue (Can You Spot the Obvious Major Rigging Mistake?)

Correction: Major Safety Issue - For the N-Rig & M-Rig configurations, the upper left directional pulley was not correctly pinned into the head of the tripod. My apologies, as I didn't catch the mistake until I de-rigged it. Luckily there were no live loads on the system, as it was for static demonstration purposes only. This is why belay systems exist!
Five Options:
1. Frame-mounted Winch
2. Single Line Directional [Not shown, but self-explanatory]
3. "N" Rig (2:1cd)
4. "M" Rig (2:1 double cd w/ Cancelling Resultants)
5. Classic "Ladder" Rig (Head-mounted Simple 4:1cd)

    Awesome vid. We switched to the “M” rig years ago and now we use the winch any chance we get. The set of fours served its purpose but it’s time has passed. And I agree, the set of fours sure does limit, if not stifle any rigging creativity. Keep up the vids. They’re the best!

    The first rigging mistake would be the open Omni block at the head of the vortex an the second mistake being the way the kootenay pulleys are rigged onto the tri links hitch shouldn’t be of significant concern due to insignificant loads being placed on those pulleys. Great video!!!

    What kind of set-up times are you dealing with as a team? I'm impressed you guys get out there and train on this specialty enough to be this advanced. Rope Rescue was always on the back burner for every fire dept. I ever worked which resulted in wasting half a class on the basics every time we trained. We were competent but we weren't as fast as I would have liked due to inconsistent training sessions. Are you happy with your guys setting up, especially when it isn't your shift? So how do you guys get so much time on rope? You aren't an officer from what I can tell, so you aren't making your crew participate😄, so what gives? Just curious and a bit envious.

    Setup times for these educational videos are roughly 30-45 minutes from the time we get on site to the time we start filming. I had all the details outlined on paper before we started & I was also anal with the rigging as it needed to be "photo-worthy" for public consumption. I wouldn't say I'm content with the collective proficiency level, especially when spanning across all three platoons... & that was one of the big motivators for me to start filming. Then I realized that there's so much more global value beyond that, hence the creation of the KZread channel & making everything publicly available. Each station on each shift tends to gravitate to their favorite discipline(s). For my crew, we tend to gravitate to ropes, plus its far easier to get out & train on little things here & there on any given day, as opposed to the more labor-intensive & logistics-heavy "campaign-like" disciplines such as Trench & Structural Collapse. It's always a tough ask to get the time to go out of service to train on these low-frequencey/high risk activities. Some of the videos we shot we were still in service & just got lucky that we weren't interrupted during the filming window. It is by no means easy to strike a good training balance among all our identified rescue disciplines, especially when we have competing & overriding priorities of medical & fire training requirements. For the educational videos that we shot off-site, I had to outline what it was going to look like in advance, come up with an estimated time-frame, then pitch the idea/intent to the bosses to see if they'd give us the green light. Sometimes its a go, & sometimes its not. My engineer is a wealth of knowledge in the rescue disciplines, especially rope, & has been a huge mentor for me from day 1. We've both sought out & continue to seek out specialty training opportunities all over the country, largely on our own dime & own time; but I guess if you're passionate or OCD about the subject then it's worth-it. I'm just lucky to be on a crew w/ like-minded individuals when it comes to pushing for quality training time, & a captain who understands the value in it all.

    @@Propeller_Head Lucky indeed. Props to your chain-of-command for supporting your efforts. I was curious if you were more than a one man show as it's always you demonstrating these skills. Glad to hear you have an engineer and crew just as interested. Two more questions: are you guys IRATA or SPRAT certified? and what does the thing on your wrist do?

    The ideas & the content "script" are all mine. When we're doing team-based rigging I'll have everyone doing specific rigging tasks, then spot-check or re-do as needed to make sure it all looks good for the camera... knots dressed, lines straight, clean workspace, etc. My department doesn't require anything other than NFPA 1006 Technician level. I'm SPRAT but I don't know ifanyone else is. It would be nice if that was a requirement prior to getting your NFPA technician training... the "on-rope" skills are what eats up all the time when an organization gives you only 6 days to put on a class for "never-evers" & expects them to go from Zero to Tech-level Hero. I control the Go-Pro remotely from my wrist.

    @@Propeller_Head I hear you on the 40 hour Tech class. For most people it doesn't result in the competence you would think it would. Hey man, thanks for the detailed responses and keep up the good work.
