How To Building of a Side A-Frame Artificial High Directional Tracking Line and Think Through The Process

Written By: Jason Ilowite

So the operation that we ran here is a tracking line offset in conjunction with a two tension rope system. So the whole purpose of the tracking line offset is to be able to take the rescue package negotiate difficult obstacles that may be encountered while they travel down the cliff face.

Outcroppings of rocks, difficult edge transitions, all of those things can be mitigated with a tracking line. And all it is, is a … we took a third rope and we anchored it well far away from the face of the cliff down below. And the reason why we set it so far away from the face of the cliff was in order to make sure that the tension never got too great in the tracking line.

We’re not rigged for a sloping high line type of evolution, so it’s really important to make sure that it stays low tension the entire time.

So we ran all of our operation through a sideways A frame that’s guyed off on both sides with two tensioned, non-working three-to-one systems.

So you can see we have our tracking line which is the blue rope which is attached to our double long tailed bow end. And as we put tension in the tracking line it simply pulls the litter away from the wall. A really important consideration with a tracking line is to always make sure that you’re not within more than ten, maybe 15 feet at most away from the cliff face. And the reason being is the more we tension on the tracking line, the farther that rescue package gets away from the wall, the greater the slam factor becomes.

And at that point we’re starting to get into a major offset. And in that case the tracking line would need to be belayed. Right now, we just have it as one single line. And the reason why we did away with that is because we’re not pulling very far away from the cliff face. So, should there be a catastrophic failure, the rescue package is not going to slam catastrophically back into the cliff face.
