SRT With DRT Gear question

[Arran Turner]

Bit long winded but...

 

There are a handful of mechanical devices to climb on like the lock jack spiderjack zig zag etc. only rated for DRT

 

What is stopping say a 60kg climber using these devices SRT without a rope wrench?

 

As opposed to a 120kg climber using them DRT with a pulley saver installed?

 

Problems being the way the device is loaded?

Gripping to tight ?

They won't be loaded correctly and you can not descend on them.

Behave Arran, you're heavier than 60kg

[Arran Turner]

Behave Arran, you're heavier than 60kg

 

I know i know only 30kg heavier though!

[Joe Newton]

Thought so.

 

I'm 65kg, and if you're lighter than me, I might have to make some lifestyle changes!

give it a go

[colemanjessenz]

they function better if they are used ddrt, I'm sure you could descend on any of the said devices but they would not perform to a workable standard.

i know that the spiderjack and lockjack are allowed to be used ddrt without a friction device when performing a rescue in competitions thats two peoples weight on one device.

Certain death:001_tongue:

 

They're not designed nor tested for srt use. The lockjack and spiderjack need the additional attachment to allow smooth function. Having said that, I've tried the LJ,SJ, ZZ1 and just a hitch on srt on their own and they all function to a certain extent, though I'd strongly advise not trying to use them!

 

If you want a compact, single device SRT system, get a Hitchiker or a Unicender mate, you can even get a uni over there without everyone thinking you're some kind of voodoo death-defying nutjob:001_smile:

Don't bother trying.

 

I have tried and it doesn't work at all. Not even nearly.

 

Plus, the device may fail and you would fall to the ground.

When you descend ddrt, the descent device is the limb that your rope is over, lockjacks, zig zag, and hitches are really only ascent devices. A rope wrench is like a descent device to work with your ascent device so you don't need the limb. I have found a zig zag + a wrench To be really really smooth.
