Has anybody figured out a consistent way to deal with the effects of friction in the pulley system?
If I use a bathroom scale to calibrate the amount of weight removed, it depends on whether I pulled the weight up before stopping, or if I let the weight lower before stopping it.
The difference in weight removed is very large in the two cases; if I use friction to my advantage I can almost double the amount of weight removed from my arms.
My way of dealing with this has been to stand tall and then drop down into the hangs, so that I am removing as much body weight as possible with each hang (using friction to increase the effective weight removed from my arms). This way I am consistent from workout to workout. |

I'm using the trango pulleys and some 6mm cord These look like basic pulleys with efficiency around 75%. Buy yourself some pulleys with sheaves mounted on ball bearings (Efficiency 95% +). Example: www.climbingtechnology.com/en/outdoor-en/pulleys-and-ascenders/pulleys/orbiter-sThey are pricey but the difference is amazing - cheating is basically impossible. It's a good investment in the long run + you can use them for some big wall adventures in the future too. |

Thanks jv91. I'll make the move to better pulleys when I am ready to upgrade my training program.

I use a Frieno carabiner on two caving setups, one with a Simple and one with a Stop. I don't use the Z because I want to be able to switch over to a rack in some circumstances and not change the attached carabiner. It's lightweight and does its job as an integrated carabiner for use with a caving descender perfectly. Compared to using the Simple or Stop with a separate breaking carabiner there it's much more ergonomic, makes changeovers and lock-offs simpler, and avoids several risks like cross-loading or getting the descender locked in an inverted configuration after unweighting and reweighting. |
