Friction introduces additional forces that can distort the resultant. It refers to how well an anchor distributes the load between pieces. On the other hand, self-equalizing anchors like quads or sliding x’s will adapt as the direction of pull changes over time. Two simple methods are shown below, along with the more advanced equalizing figure-8. Minimizing Friction.

Dec 10, 2012 · Each piece in the anchor should share the load of the anchor force equally. A. This maintains a lower force on each piece, therefore decreasing the likelihood of anchor point failure. They tend to be predictable and are allow helpful if you are belaying from up top. For example, if an anchor point was deemed to represent 75% of the overall strength of the anchor system, then ideally 75% of the force applied to the focal Oct 10, 2023 · Equalized. CHECK HAZARDS anchor-building pedagogy has been to encourage riggers to identify the stronger (or weaker) anchor points in a given anchor system and ‘favor’ them appropriately through thoughtful rigging. Above the knot that creates the master point, there will be two strands of cord running from each piece of gear (you must have at least two pieces for this to be redundant) into the knot.
