Best midline loop for leapfrog winching heavy object -15ft then switch to next loop

At least “verbally” I ran across a knot with similar missions. and that is the “Artillery Mans Loop” or something similar and the story goes that 20 or 30 men needed to pull cannons up steep slopes in the civil war and they took long ropes and tied loops for each man to grap hold of to pull the cannon um the hill. I dont know how easy the loops were untied but the loops closest to the cannon ultimately must have had some pretty strong force pulling on the rope. At least I have this knot with photos showing me how to tie it. What are the opinions of this knot ?

As i mentioned in my previous posts, the artillery loop, or man harness knot, or Abok #1050 harness, (all these names refer to the same knot), does not appear to be so stable in heavy loading situations, as in your application.

I would not risk using it, because there is a distinct possibility for the nipping loop to be deformed into a straight line (noose) with only one rope diameter passing through it, if loaded from this side.

I also see respective probability distortion, if the knot is loaded from the other link, that is to say, from the SPart directly linked to the collar that encircles both eye legs.

The knot i gave you previously, (wheel knot) let’s just say it’s an improved harness form, for the following reasons…

  1. More nipping loop stability with now two rope diameters passing through.
  2. More manageable and fully releasable collar(the upper rope segment that encircles the eye/loop), because it is not linked directly to the Spart, it cinches directly from the eye leg.
  3. Even if the knot is loaded from the more complex SP side( that is the side that uses more rope) it won’t jam, although it is recommended to be loaded from the less complex side.

Whatever the load, bend the collar, open the nipping loop, in this order, and the knot is untied very easily.

It should be noted that the #1774 2-eye Bwl extension
I’ve advocated uses a lot of rope compared to simpler
knots. It looks great for handling the forces ; but the cost
of tying up such a bulky knot might affect use, alas.
