My quibble with 11mm is i dont see it as a equal strenght to 13mm if it was i would use it but i feel its weaker but i have never used it hence im after your opinions

 

Climbing lines are very, very strong!

 

Around 3 ton I think.

 

I have used old ones to pull wagons out of fields, they take some real effort to snap!!

All climbing ropes available specifically for tree work conform to en 1891.

 

I don't know the minimum strength requirement to meet that standard but it would be around 2.2kn and 2.4kn.

 

Some rope may be stronger than that but none weaker. If an 11mm is on the weaker side and it rates at 2.2kn using a safety factor of 10:1 (highest saftey factor) that give you a safe workign load of 220 kgs.

 

For simplicity we use 100kgs per person, so your rope could hold two people in the event of a rescue and still be within the SWL which is only a tenth of the overall strength.

 

If you only weigh 85kgs ( those days are like a distant memory for me) then 2 and a half of you could climb on the rope all day long and be fine and it would take 25 of you to break it!

 

If your that worried about the rope bein gstrong enough I suggest having a seperate belay line or additional safety equipment such as a chair and a desk.

Actually its quite an important point raised here. We do all think about the strength of our ropes, our non tree climbing friends say "you must have good faith in your ropes?".

Cutting your rope aside, how many accidents occur from rope failure? I don't know but not many I would think.

More accidents occur due to karabiner failure, mostly due to locking krabs not locking, which in turn is due to lack of inspection.

Buying a rope based on the fact that it is holding your most valuable assett, your arse, is short sighted! Its the Krabs,cambium savers, friction hitches et all that are holding you in place, ignore them at your arses cost.
