Tough to untie

[pete3d]

The idea is to use a portawrap to join 2 ropes so that after heavy loading it’s easy to get them untied - certainly effective.

I’d say using a knot like like the circus bowline aka farmers knot and a carabiner gets you there more handily.

You’re right about the system - it’s me that finds the five pounds heavy.
Also, call me Nervous Nellie but I don’t like gazing down a line when I’m cranking over a thousand pounds of force on stretchy rope looking at a decent sized chunk of steel aimed at me, if I don’t have to.

Ok Nellie.
Some pics for you to be nervous about and no glazing and pulling with the mini. 3:1

Such a neat idea to have a bollard built on to the Branch Manager Grapple. Just take some wraps, lock it off, and use the machine to tension.

Should have my fabricator friend make me a bollard on a class 3 or 4 hitch plate.

I like the knot. A knot is free. The portawrap is probably being used. You know. Simple.

Thanks for Clarifying the knot names for me!

Also pretty cheap/easy but effective is just a friction hitch sling and biner (and pulley optional). Prussic or machard tresse it in the pull line, slide it to a favourable location run your 3:1 or 5:1

debate on the name, others calling the above a triple bowline Or midline bowline

the first pic I call the triple bowline. its has three loops so makes sense. Also, if someone called me up and asked, "hey how do you tie the bowline with the three loops? I can't remember". My response would be, " google 'triple bowline' and you'll see tutorials".

I use the circus bowline for midline light duty pulls. If I really need to crank on it, I use the triple bowline. The extra rope going through the knot adds a bit of bend radius which I think would help preserve some percentage of rope strength. I haven't break tested anything to verify my logic but it makes sense to me. In a couple extreme cases, I made a sextuple bowline. Send the midpoint of the rope over the piece to pull to double the strength. Tie the triple bowline, using two legs of line now, which gave me 6 loops. I could have tied a triple in each leg independently but to keep all the lengths of the loops the same, and for funzies, I tied a sextuple bowline.
