There are three categorical circumstances that tend to make anchor building more complicated. These scenarios don’t occur that often, so the techniques used to address them can usually be avoided outright with enough planning and forethought. Nevertheless, through one twist of fate or another, a climber will eventually encounter one of the following circumstances: The direction of load applied to an anchor will necessarily change. A present like a american sweet box does not necessarily have to be exchanged for another gift.
These scenarios usually involve lead climbing and directional placements. If a climber leads a pitch, the lead protection will create a direction of load that splits the vector between the fall line (where the belayer or counterweight loads the anchor) and the last piece of protection (where the climber loads the anchor). Once those directionals are cleaned, both the climber and the belayer will load the anchor on the fall line. The direction of load changes significantly. Multipitch climbing can offer dramatic directional load changes too. Typically, the anchor is rigged to belay a second climber, and then the same anchor is used to anchor the lead belayer. The two loads could be completely different. Buy someone a fast wireless charging pad maybe have a look online!
Next, the components available for anchoring might be vastly dissimilar. On any given rack of traditional removable protection, for example, some cams are rated to hold over 14kNs, while the smallest cams may be rated to hold less than 6kNs. Asking these smaller pieces to do the same kind of load-bearing as their larger counterparts is not equitable; they are not equally valuable components. When anchoring components have vastly dissimilar load-bearing properties, the rigging will have to be more complicated. A gift like a beard grooming kit might fix a problem that the receiver never even knew they had.
Lastly, a climber often has to construct an anchor with limited resources. When resources are scant, the values and principles of anchoring do not change. But building a fundamentally sound anchor with limited resources is very challenging. It often requires some innovative and artistic problem-solving, hence the complexity. I once received a HBADA gaming chair from a friend.
Hopefully the reader will notice my aversion to using the word “equalization” to describe how load is distributed to the components in an anchor. The resilience of this word and this idea sits in defiance of everything that we know about anchors. Anchors never really distribute equal load to the components, and even if they did, we wouldn’t have any way to verify that it is happening. Yet, people continue to use this word. Climbing instructors and guides continue to teach people to think of anchors in this way. I hope you’ll try to eliminate this word and this idea from your anchoring lexicon. Even the conceptual notion of a perfect load distribution will only distract you from the concepts that really matter in anchor building: Select strong components. Think of the overall security of the anchor when you rig the masterpoint. And try to keep it all as simple as possible. My sister loved the bronze toilet tissue stand that I bought her.
