High Angle Litter Positioning & Orientation While Under Load

Corrections: For the upper attendant position I could have made the bridle profile taller to avoid having to sit on the patient... that or either attach a rope grab above the yoke & sit higher up than the clearance that the AZTEK allows for.

Bob, I've spent the last 20+ years trying to perfect my litter bridle. I recently split my AZTEK on the foot end and love it. Today i spent a bunch of time making 2 separate head end MAs out of 8mm cord and prusiks, then finally realized all I needed was to keep the Progess Adjust lanyards and just added Rollclips at the top, and boom, they're independent 2:1s. It works pretty well to have the head end be load sharing and the foot end be load distributing / self-equalizing. Thanks for the info.

[@Propeller_Head]

Right on. So your Adjust lanyards have the cams toward the yoke? or are they located at the litter rails? & the Rollclips are clipped into the cams of the Adjust lanyards? Rollclip A or Rollclip Z?

[@JimT225]

No the cams are on the litter rail, but they're the 2 meter length, so there's enough length to go back to the top thru 2 Rollclip As. Also on the head end, both lanyards are connected into a single large pear-shaped carabiner, which is then clipped into the collection point, which is 2 loops of rope. I might have to put in a mini rigging plate on the head end side if it gets to be too much. So far so good though.

@@JimT225 Ahh. Ok I think I can visualize it now… So 2:1s w/ a final change of direction through the Rollclips at the yoke. Does that mean that in total, for the head end bridle at the collection point/MAP/yoke, there’s basically 4 connectors coming in? If thats the case I can see how a nice compact 5-hole rigging plate would be a clean addition

[@JimT225]

​@@Propeller_Head Ya a plate would keep it clean for sure. The biner I'm using is a Petzl William, so it does have quite a bit of room at one end however. Also, I really liked your comment about how you like using 2 rope loops as a collection point vs. a rigging plate. My pet peeve is steel rigging rings. I never liked them. I have used rigging plates for a long time, but now I'm going full throttle on the double rope loops. But I should probably honest with you Bob and tell you that I've always liked the inline figure 8 tied in 2 ropes at once. That way I don't have to find the ends of the ropes and feed them through. 😄

Good content

[@Propeller_Head]

Thanks!

Can u show the actual set up on basket and how its set up with aztec n the two connecting points on top

[@Propeller_Head]

I actually have a separate video all about how to rig the litter. Go to my playlist called "Litter Basket Rigging & Manipulation" & you'll find it there.

Whats the aversion to a rigging plate rather than putting the stress on a pair of bowlines?

[@Propeller_Head]

The stress on the loop of a bowline is irrelevant. Either way you cut it, you need some kind of knot somewhere to complete the connection of the rescue package. The Bowline works the best hands-down over Butterflies or Figure 8s. The knot has a low profile which is a big plus when you need to maximize real-estate height when using high directionals for edge transitions, or for confined space applications.
Although many people gravitate to using a rigging plate because it feels more friendly & intuitive to use, it is merely additional unnecessary equipment that you do not need, plus it adds more profile to the rescue package which takes away your usable height clearances (as mentioned before). Also, the more pieces of gear in a system, the more potential for something to fail, mainly due to human error in rigging. Not to say that you shouldn't use a rigging plate. It's fine. I just don't like the additional stuff that adds to a high profile.
