Ddrt, one prussik or two?

[normandylumberjack]

Hello all,

I was wondering what is the norm, or favour with prussiks on a doubeled rope?

Here in France the norm is a prussik on each line, with a biner on each to the bridge. Upon reading tree climbers companion and watching the odd video on youtube, i see only one prussik wrapped around both ropes.

 

What is the UK thinking on this, regs. etc. We dont have HSE here so wondered which method is considered safe in Blighty?

 

thanks in advance guys.

Are you talking double rope footlocking or doubled rope work positioning?

One on each rope

Foot locking, sorry should have been a bit clearer.

I love the way you guys do it in france, with two prussiks on an extendable bridge, and then just set off working with one of the prussiks and shorter bridge, genius!

got to make sure you got stopper knots on both end i imagine

Yes definatly!! Once you have worked one of the prussiks to the end of the rope you can then carry on Ddrt as normal with only one tail but to start with the are in the middle of the rope with two tail ends and you can then use either the left or right handed prussiks, its genuis and madness but both of my psychiatrists say they are the same thing!

I wonder if you could have a double pulley under then to slack tend both at the same time for coming in off a branch walk.
