Quick and dirty setup for ascending and descending a fixed instructor´s rope.

Use the gear you already have, to work efficiently on the wall.


This blog was not supposed to be about technical stuff. No gear tests, kilo-Newtons, knots, or steel alloy classification. There´s enough of that on the www already.  But I plan to make exceptions now and then, for either of two reasons: because I want to discuss the truth (or untruth) of something we often teach, or because I want to highlight techniques practical in the instructor´s daily work. In this case, it is the latter.

Whenever we have climbers on the wall, we like to have at least one instructor there - to teach, goad, double-check, and provide safety backup. We want to be able to move both up and down, and sometimes even sideways if we are supporting two climbers. What is a good way to achieve this?

There are many solutions, the most obvious one being to ascend the rope on jumars using regular big-wall technique. This, however, is gear-intensive, slow going up, and even slower going down. It may be the best solution for steep climbs, but these are less common when instructing. Personally, I only bought jumars after fifteen years of instructing, and that was only because I started teaching aid-climbing. This is probably true for a lot of young instructors.

Therefore, I propose a more light-weight method, using cheaper and more commonly available equipment. So, for the first time ever on this blog: here is a short video!




In summary:

  1.  Put the a grigri-like device on the fixed rope (preferably a static one).
  2. Attach an ascender or rope clamp (any type) above the grigri. 
  3. Take the rope at the passive side and loop it through a screw-gate carabiner attached to the ascender.
  4. Pull on the rope coming from the ascender, while giving yourself a little push with your feet and hips.
This setup allows you to give yourself a 3:1 theoretical advantage (in reality, friction eats up a lot of that). You can free-climb and just take up slack on the grigri. You can also pull on the rope coming from the ascender, using your feet for an additional push whenever possible. If it gets steep or slippery, connect a 120 cm sling (or adjustable aid ladder) to the ascender and use this to stand on.

It´s not rocket science. The setup is simple, and yet very safe. The whole system depends on the well-proven track-record of the grigri (or similar device). Remember, if you want to work hands-free, make sure you have a backup knot not too far below you!

The greatest advantage, apart from simplicity, is the ease by which you can now move downwards. For a short drop, just leave your ascender in place and descend on the grigri. Make sure you have plenty of rope, since it now runs three times between you and the ascender. If you are done and heading all the way down for a coffee break, first remove the ascender and take if with you.

Note: Rope access workers and arborists will have other techniques, but more importantly, they will have dedicated equipment. The method described here is useful mainly because it requires so little in way of specialized gear.

When to talk about the dark side of climbing

Image
People get hurt. People die. Yet climbers will climb and I think this makes the world a better place. So how do we talk about this with our clients? I am not going to provide any answers here, because it is something I wrestle with myself. But I will try to organize my thoughts, and hopefully, this will trigger some input from my readers. The reason we are in this business  - teaching climbers all the survival skills - is that climbing is dangerous. Very dangerous. Every year, lots of people die or get seriously injured in climbing. It seems only natural that we should be transparent about it. Why? Because studying accidents is how we can understand risk, and develop both safety culture and safety technology. On the other hand, ambushing a nervous beginner with tales of death and suffering hardly seems inspirational, does it? What, then, could be the middle ground? I believe that facts and timing matter. Let me explain. The reason we need to talk to students about accidents i

The Bandwidth Problem, or The Importance of Not Teaching

Image
Remember that we are not a circus. Our job is not to show off the maximum number of tricks.  To teach more, sometimes we need to say less. At the end of a two-day course, my voice is always shot, and I croak my goodbyes like an old frog. For many years, I have tried to practise my own philosophy of teaching, and talking, as little as possible. Yet I keep yabbering on. Whatever country or training system you are working within, you probably follow some kind of syllabus. You are expected to tick a number of boxes: anchors, rappelling, knots, climbing technique, access, grading. Check, check, check. Many participants will greedily ingest everything you throw at them. But people are different. If someone is completely new to the exposure, the engineering, the group - then a day or two at a crag is going to wear him down. Stress, cold, individual learning styles, or group dynamics will further affect his capacity to learn. In the end, it is a simple fact that just pulling from you

Tying off a Munther hitch - skip the Mule

Image
Knots should not just be useful. They need to be easy to teach and hard to get wrong even under stress. A very important skill for any climber is to be able to tie off a belay device or Munther hitch. Whenever you need to get your hands free for a snack, a photo, or transfer loads in a rescue situation, that passive end needs to go somewhere. The classic solution, especially in North America, seems to be the Munther-Mule. It is safe, can be released easily under load, and most importantly, knot nerds (like your average climbing instructor) like complicated knots with unintelligible names. If you are not sure what I mean, here is the Animated Knots page ! The Munther-Mule combination. The backup half hitch has been omitted for clarity. I should start by making it very clear that this is a tried and tested method. Technically, there is nothing wrong with a properly tied Munther-Mule combination, and if you like it, use it! But I strive to teach knots that are easy to use,
