Rigging anchors for balanced load

- This video has been extracted from one of our rope rigging training programs (Australia).
In the video we present two rules of thumb for achieving balanced load onto two anchor points.
We also uncover some of the misconceptions relating to balancing load between two anchors points.
Best watched on a monitor but still good with a smart phone. - Jak na to + styl
A clear, simple method of teaching this without having to work with vectors. The frame and load cell setup is great. Love the laser and Omni Block setup, top idea.
learnt more new things about Y hangs, and had my pre-existing perceptions challenged more, than I have for years.
Thank you.
Thank you for another excellent presentation.
I propose calling the "I", "IFFY" instead of IDEAL in the I, Y, T method !
Outstanding presentation... Thankyou very much!
Excellent video! I've been sharing it regularly with people struggling to understand the concepts. Kudos.
Great presentation Rob. Thank you.
Thank you Rob... An essential tutorial for all climbing sports too..
Great video sir! A great tool that explains the complexities of anchorage systems.
excellent video! I picked up a few gems of information for my rock climbing anchors setup. (strive for minimum 30 degrees now!)
Excellent Video! Thanks for putting the time in to put this together.
Thank your for this simple explanation of rope angles :)
Brilliant as usual Rob.
Excellent video! A great tool that explains.
wow! excellent video, explains things very nicely!
Excellent video! Thank you!
Explained perfectly, thanks!
Great info and demonstration, thanks.
Fantastic demonstration thanks mate!
Excellent. Thank you.
Great video, great teacher
Good Teaching.
Very clear and interesting demonstation. I'd love to see a video showing the loads generated by the american death triangle.
great job mate
Great work.
Very nice video!
Great very interesting video
This is great!!
Excellent.
nice video..but could you please pan the sound in the middle next time? :)
Thank you
great vid thanks
The 2 degree increase from 150 to 152 degrees in angle doesn't give a 25% increase in loading (7m40s), but a 25kg increase. That's about 12% of 190kg.
Great instructional video, however I'm still not too sure about why using anchors less than 30 degrees is dangerous. I see what you're saying that when the load is not balanced you will have uneven stresses on the anchors, but that is the same for anchors between 30 and 90 degrees, as you have demonstrated at 90 degrees. Why do the 'below 30 angles' get relegated to the red dashed line club?
because, as he says, you can massively alter the loads with only a tiny shift in the bisecting angle. this makes it less consistent, and give rise to the sudden risk of spiking up to a sudden huge load on one anchor. the larger angle does render the anchors subject to such sudden fluctuations. he's not saying uneven stresses don't occur in the 30-90 range when the bisecting angle is not central; he's saying to be wary of tighter angles because uneven stresses have bigger consequences with less change.
