Spiderjack 2.1 Dyneema issue

[skip]

I checked the instructions and they are very clear on putting the spacer between the jack & sling, hope that helps

 

also if the red joint did wobble undone, not that i can see quite how it can being you'd have to disconect the sling from your krabs or am i missing something? furthermore if it did come undone it wouldnt result in a fall simply an inconviniance as it would struggle to self tail, just like when the old velcro used to snap undone?

This is true,it is for allignment but should be reguarly checked and tightened with the allen key when nescesary.....

skip. You would want the worst case scenario to be as you described - an inconvenience. However, as I pressed the black lever down you could clearly see contact first with the little ring then with the sling. The ring sharpened the angular edge of the spiderjack casing (due to metal on metal) and then started cutting into the sling, but very slightly. This would have eventually lead to a fall if gone unchecked.

Lancstree i use the rubber rings for the sj setup however on my way down from a 70ft beech i noticed the red joint was wobbling a bit.after a nervouse decent i found that it was barely screwed in:thumbdown:. Feel a bit guilty that i didnt report it on here now. Thought it would be a common problem. I havnt had any fraying in the dyneema tho.

 

Stay safe

Thanks for letting us know Jake. Which way did you arrange the rubber spacers?

Was using all 3 (outside dyneema,inbetween,outside the jack) until about 2 weeks ago. I was finding it abit annoying putting all 3 on so was missing out the middle rubber. Thanks for the heads up as i will now allways use all 3 with the jack. Stupid as it takes less than 10 seconds to put on.

 

Stay safe

I noticed my adaptor was lose the other day but no issues with the dyneema being cut, will keep an eye on it , cheers for pointing it out

Could the issue be the oval crab with its small top? Maybe an Hms or similar be better

Good point Ewan i wondered that but my set up uses 2 DMM ovals but with the rubbers set in the recommended way my Dyneema is as good as new...

I don't think a HMS crab would make much difference really. I've checked the instructions and they are very clear on how to arrange the rubbers. When I first set it up we had the new spiderjack and rope in the van and hastily put it together on a rainy day to try it out. This should have been done back in the workshop following the instructions carefully. The damage seems to be down to the rubber forcing the dyneema to an angle towards the body of the spiderjack.

 

Before getting the spiderjack I had read the warning thread on here about making sure the little ring is connected to the carabiner. I guess this made me over cautious and thought the rubber would be better placed where it would not allow the ring to come out of the carabiner when the gate was opened. This was the error.

 

I'm glad that people have read this thread and taken it seriously because I don't want anyone to make the same mistake. I wonder if I should inform ART that this has happened so they can look into it?

Thanks for sharing this I have noticed wear on my sling. And I have the rubber in the correct position!
