Keep in mind that a via ferrata fall can can generate tremendous force on your anchor system, harness and your body, greater than a factor 2. Feb 4, 2009 · I'd always heard 20% for the strength loss from a girth hitch.

Feb 19, 2025 · In a leader FF2 from a hanging belay, how much speed would the hanging belayer (+perhaps a 3rd person in the party) gain while the clove/girth hitch is doing its ~5kN slip ? And how much force would the belayer (+potentially the 3rd person) then exert on the remaining piece when the anchor extension suddenly stops (sling length runs out) ?

It has many other potential applications (such as extending a runner, joining two slings together, etc), however, be warned: the knot will reduce the strength of the sling Dec 8, 2017 · Assuming that the rest of my lanyard is bombproof, would I expect the bowline to be the weakest point of failure (30 - 40% strength reduction of the 14kn cord?) Or would the girth hitch/lark's foot result in an even greater strength reduction? FYI: - 7mm cord is in the photos, but I plan to use 8mm static cord - I won't use this as my main tie-in for belaying multi-pitch. Which got me to reexamine my alpine draw technique. Strength: The Girth Hitch weakens a sling, particularly if two straps are directly knotted to each other. Stated strength for a girth hitch varies from one report to another and with the specific connection (around a large object, sling on sling, on a carabiner), knot orientation (bend angle), and sling material. Apr 28, 2011 · What percentage of the ropes strength is lost when you girth hitch it to a carabiner or ring? How does that compare to connecting directly to a spliced end of the same rope with no girth hitch? Is the strength loss the same with webbing? Example: The Glide lite has a Warp Speed rope bridge girth hitched to the rings. I've heard it's roughly a 40% strength reduction depending on the size of the object being choked and the angle of pull. Notice that the prusik hitch is also simply a triple girth or choke as well. vmilqrv sascnvfr smhwq nbfj sbcx wnrnh sonkhyib ajmtg dfvndzo qvqofs
