HUH??
"Basic rigging physics" for the sliding-x is equal tension on all legs and equal tension on the two pieces no matter what the angle and position of load. Any unequal leg tension would be cause sliding of sling until tension is equalised.
Of course stepping away from basic rigging physics and you have friction on the karabiners and the x itself. This friction limits the extent of movement and complete equalisation doesn't occur. |
