loading carabiners

[DrewB]

Heres a good example of incorrectly loading a carabiner. AP spliced class 1 onto Yale arrow frog rope in a VT setup. The fishermans knot on the arrow frog loaded the nose of the carabiner and snapped it at 21kN. Still a massive amount but expected a lot higher than this

Thats impressive Drew, I assume you were destruction testing on some form of rig, could i be rude :blushing:and ask if would it be possible use you images for instruction purposes?

very interesting

 

would the incorrect loading be lessened if the fishermans was in between the two legs of the AP?

The fishermans is taking 50% of the load, the eye splices 25% each, so the fishermans should be nearest the spine.

Moot point Peter.

Drew, you need to eat less pies bro....

A loss of 3kn when incorrectly loading it does not seem bad at all to me.

 

A full on cross loading rating would be 7-9kn & open gate a similar amount. For it to cope till 21kn is good not bad.

[DrewB]

it wasnt a total crossload-when it was on the machine it looked setup sweet as per norm, i think it just highlighted the problem. I imagine using knotted hitch cord,pulley,knotted climbing line will see a dramatic loss-i feel some breaking coming on..

and dave, of course you can use it bro.

hows it a moot point? the carabiner is being loaded incorrectly. its a way we all use but that doesnt mean its the best loading method. day to day the loading isnt an issue until you reach the breaking load.
