Albere,s Bonkers Spiderjack SRT thread

[Joe Loggs]

I tried it with a hitch in various set ups too. From what I've done,I can't see it coming anywhere near the wrench. Just need to lay my hands on a spiderjack to try it now.

 

Mate the wrench is for sure a lot smoother, but if it allows someone to access a tree srt and descend srt then that's a handy little tool to have if you don't want to fork out on a rw and go down the hole srt route.

Thinking about the 11 vs 13 thing...

 

The advised bend radius for rope is 8:1, though generally accepted in tree work 4:1. That becket is only small, so imo pushing it to be using it with 11 (44mm bend radius) so using it with 13 (52mm) is really not good. I can imagine that 13 will flatten and splurge quite a lot, severely weakening the rope where it bends at the becket.

Sure is, I'm not saying it isn't. But, a hitch on srt will get you up there, a munter will get you down. Thats surely the cheapest way? Though perhaps not the advised method...

Il leave my ideas for the pros ay lol. Not given up on my tube rw tender tho😄

Keep going, might lead to other avenues of ideas. Keep innovating, i only think of ideas after someone has invented them

Didn't mean to offend you mate, keep at it! Someone told me once, the tree climbing industry needs these "mavericks" experimenting in order to move forward. I reckon you're now one of them:001_cool:

[Joe Loggs]

Dan you didn't offend me at all you have done me a favour by doing the science as I am clueless. 👍

[Dan Curtis]

Are you still playing with this setup Joe? Had a brief ponder whether any other pulleys might do the same as you'd intended today. Might do some playing about and see what I can come up with

[Joe Loggs]

Hello dan i have not had the chance to be honest. Have a play I'm sure you will come up with something. Hb do a good range of different pulleys.

Just had a thought about using a hc set up the wrong way, I'll put it together and try it.
