- A short film on loading of tension lines in rope access. This is not a scientific test just a guide. for further info visit our website or book in for some training at www.access-techniques.com. Oh and an Id slips at 6kn ish, so is The best piece of kit to use for the termination.
We Train all IRATA levels every week in our 15 meter high indoor training centre in Sheffield. 5 minutes from the train station, and 1 hour by train from Manchester Airport.

Found the App he's using. It's "AngleMeasure" by Pool Night Studios.
Vector loading does indeed increase anchor loads exponentially. That said wire rope does stretch, maybe not as fast as a static/minimal elongation rope, but everything stretches. 9.5mm (3/8”) 7x19 IWRC EIPS wire rope has a minimum breaking strength of 6,500 kg (14,400 lbs). In an application where wire rope has replaced static rope the anchors should also be upgraded to appropriate strength to maintain a 5:1 safety factor. Also there is a limit to the length any rope can span (wire or static) and still maintain an appropriate safety factor. I would be hesitant to rely on double 9.5mm wire ropes beyond a span of 365 meters (1,200 feet) in this application. The weight of the material it self becomes a factor at long lengths, as the above mentioned cable weighs .37kg/m (.25#/ft).
very well explained , thank you!
Great video, thank you.
But I stay with a question: so what do you recommend if I want to install a zipline with wire? How can I make the calculation?
Thanks in advance
Great informative video! Me and a few friends did simular testing 2 weeks ago. I came to the same conclusion that it is really hard to go over 160 degrees without resorting to crazy mechanical advantage systems. Which is a good thing ofcourse.
Did you do any testing when using the ID as a progress capture and see when it starts to slide?
Oh and what app are you using to measure the angle?
Very good, I am interested in the figures if the diameters of the ropes are greater say 11mm and the tightening system is using prussics an pullies with 50 mm slings on bombproof I beam anchors, where the weakest link may lie...especially with say 50kg drops of say 1 meter....?
Very eye-opening. Thanks for sharing all that knowledge, even in those other videos. I really appreciate!
Bizimkiler de böyle video yapsa ölürler! Bişey öğreniriz sonra Allah korusun 😏
Anyone work out what the app is at all?
what tension on main rope ?? If on each side force 100kg left and 100kg right than on rope it will be 200kg ?? thanks.
Great Video!!! thanks for all the info
Thanks for the vid.
Very useful.
Is the weight the same if you double one rope or do you really need two different ropes?
What do you recommend?
Whats that app called?
Thanks, great video, do you think Italian hitch locked off would be safer than using I'd, stop, ect? Or too much friction?
Cheers
Thanks, great video. Do you think using a Italian hitch would be safer than using hardware, ie I'd, stop,rig?
Hi, are you shure that the measurement of angles si ok making ir with diferentes sides of your phone ?
Great video, these forces generated can really overload the anchors. Thank you again.
So my weight is 117 kg. If i want to work on this area should i lose weight?
Excellent presentation. Thank you!
Super clear and creative! There are still a couple of questions lingering in my mind after this video. Like is your rope static or dynamic. What kind of objections do you have when you are using prusik knots are Grigri? Keep up the good work it's the clearest explanation of this topic that I've yet seen!
We use low stretch rope - 11mm EN 1891. When I've pull-tested them, prusik knots behave unpredictably. Grigris are belay devices for rock climbing - in both cases a stronger, industrially rated item, is available, so we use it!
nice app you got on your phone !! whats the name of it please ???
Really appreciate the great work your doing. Thanks mate
Well explained and great demonstration, thanks for sharing
What beaks first? Anchor or rope?
i've got this question for years, now I got an answer, many thanks
is that Tyrion Lannister?
Thanks for sharing guys, great to see the theory put to practice.
Great video, my friend
can you do some more videos on rescue rope gear please
Excellent demonstration.
Well explained, thanks!
Bell video. Buon lavoro..grazie!!
Awesome video and very informative !
that's brilliant! thank you!
Awesome
For flying fox’s in advanced rigging we weigh X span, divided by 4X the sag in the line. min sag = span X0.05
