True, 3% to 5% elongation is a generalism for most 11mm static ropes but can be higher if a skinier static or dynamic rope is used.
I use a 10mm static or an old dynamic, and have never had a bad shock loading on a slump onto these systems.
But I also recomend no exesive amounts of slack be allowed to enter the sytem
Whatever system is used, this is the most important to reduce any high loadings. |
