Friction hitch/split tail, what diameter ?

[Tom D]

For an open Hitch such as a blames I believe that 10mm is the minimum and for a closed hitch like most of the others 8mm is the minimum, so long as the WLL is acceptable. Since in a rescue situation you may have the weight of 2 climbers on the one cord then with a safety factor of 10 you really ought to be looking at an MBS of 20KN or there abouts for an open hitch and 10KN or higher for a closed one.

I do use single climbing rope which is a semi static by Beal. The cord I use for friction hitches and tying from the climbing rope to harness is static at 7mm and works well. My query is whether I need to go up in size for strength or is the 7mm good enough.

PS.. my boot laces are leather so maybe not strong enough.

What's the rated strength of your 7mm cord?

 

Are you just using a Prussik on a single line? Or a doubled line?

[Peter]

What is your 7mm cord rated at and what hitch are you using?

My 7mm cord is rated at 13kn, and it is used with a Blake's hitch as a fail safe on the single climbing line. Having tried most of the hitches the Blake's works for me.

My upper Petzl handled ascender is rigged to my harness with two 7mm ropes, one to each side. This gives me more hand room for the Petzl handled ascender fixed with a looped 7mm rope to my webbing foot loops. Also use two lanyards adjusted with the Blake's hitch. I like belts and braces so to speak.

Have you had any training in tree climbing? CS38? Honest question.

[Ollybean]

No training received, just self taught free climbing for 50 years and in the last year resorted to the gear and reading "The Tree Climbers Companion" by Jeff Jepson.

Although a USA publication it has a lot of relevant content. I cannot find an equivalent book published in the UK.

Still mate, regardless of training, I would still use arb specific kit. I will make it easier and if you have been free climbing 50 years then you have a knack for it.

 

Arb kit may make it easier in the long run.

 

Are you work or reccy climbing?

[Ollybean]

I own a piece of land with a public path on it. Needs maintenance to keep Joe public safe and supplies me with fire wood for the good old stove. Nice recreational stuff with no pressure, except --- I work solo and the general public ignore all my warning signs and wander past when I am working, if I am not vigilant, with no idea of the danger.

Either side of the work area are warning cones and then a warning notice to "stop and warn of approach". Also tried rope barrier but they duck under it. I have proximity alarms as well to alert me. Its no good applying for a footpath closure as I never know when I am going down to work and how often.
