Why static rope not rock climbers rope?

[Rupe]

Another way of looking at it is, rock ropes protect you from a FALL of some distance(often quite a bit)

 

In tree work you are not allowed to fall, we work in "work positioning" style. We do not "fall" cos we are tied in with minimall slack, so no need for shock absorbing ropes, just ropes that actually hold you where you are supposed to be.

As usal lots of info from out there...thank you for awnsering my qery.

Most rock climbing ropes are 11mm which is to small to get a decent grip, arb ropes tend to be 13mm.

No 13 mm ropes here, 11.5, 11, and 10 mm all the way.....

 

Also modern rock climbing ropes are mostly thinner than 11 mm, anything down to about 8 mm is normal.

is was lead to beleive it has to do with shock loading anchor point, dynamic rope (rock climbing rope) is designed to stretch as a fall takes place, if it were used in a tree and a fall ocoured the chance of failure at the anchor point is greatly increased?

How?

 

If the rope stretches, it acts as an energy absorber, thus easing the loading on both the load and the anchor point.

8mm on a double rope system surly? No single rope is that thin. I have a single that's 9.5 mm (beal) and that's thin enough thanks.

I have a thin arb rope blaze and don't like it as its too narrow to afford a proper grip. I like 13mm for trees.

Arborist rope is semi static. Climbing on static line would be really nasty if you had even a small fall.

Yeh, I'm going back to 13mm

 

Might use my tachyon 11m as a tow rope
