What kinda knot is this?

[DonaldRobertson]

What kinda know is this and what is the purpose of this knot? Can if be used for lowering small branches that weigh no more than 50 pounds? Just curious. Its the know on the cover of the tree climbers knotbook.

Can't see it without a myspace account, maybe host it in another place.

 

[Blinky]

Same here, no myspace account. Can you host'em somewhere else?

 

[DonaldRobertson]

How do I post an attatchment on here so you guys can see it it? I've never posted a pic on here before so I don't know.

Did you buy the book? maybe it will say in side. looks to me like some sort of blakes hitch. just up side down.

 

[Blinky]

It's a Blakes Hitch, 5 over 2, there's no harness tie-in in the loop so it looks funny.

Looks like a blakes hitch based "slide and grip" knot. Same idea as a tarbuck knot. The loop side is attached to an anchor and you slide the knot up to tension the line. Great knot to tighten tarps when camping!

Yeah, in german its called like "Blakes Sling".
Adjustable Eye that holds its size.

Why would you ever want to tye a knot that could only hold say 50#'s? With a 10-20# limb falling couldn't it generate 50#'s of force?
I feel a climber can do any takedown with two knots. The Clove Hitch and the Running Bowline. There may be variations at times like a Running Bowline with a wrap or a Half Hitch or Marl. The same goes for a Clove Hitch.
Why complicate things keep it simple. You will benefit in the long run.

 

[Blinky]

The Blakes isn't a rigging knot, it's a friction hitch. You wouldn't use it for tying off wood.
Like wesco says, a running bowline will hold pretty much anything except small diameter branches. You can go with a clove on those but back it with 2 half hitches. The clove hitch isn't a rigging knot either but it's been pressed into service by tree guys... sometimes with bad results. I know of one individual who used a clove to tie-off on a spar, it rolled out and he fell. He was seriously injured but is still around to tell about it.

 

[Backyardboogie]

yea i had heard that the rule of thumb for a clove hitch was that after about 1000 lbs ie. a fall or rigging, it starts to slide out

 

[Rookieclimber]

hey boogie, you have to back up a clove hitch with at least one half hitch while rigging to prevent this "slide out"

 

[Tim_Murray]

I agree, keep it simple. The running bowline or the clove hitch are your everyday knots for rigging. When training your ground crew this can prove to be more efficient.

Potentially less than that... diameter and bark texture are critical factors. If you do some looking on here you'll find several accounts of cloves rolling out when used for rigging. It's a great knot, my personal favorite but I don't use it for rigging except tying off bouquets of small limbs. The running bowline is a bombproof knot, quick and easy to tie/untie.
