Zz/spiderjack ariel rescue

[andymum]

Right guys, this never occurred to me until the other day,

the zigzag has a 140kg weight rating on it, don't know on spider jack yet as no one has responded.

 

so if as me you only use these on your set-up what's the solution for an Ariel rescue ???????????

 

the solution i came up with is a long prus above zz and clipped onto harness. other than the obvious back to hitch climber.

 

what are your thoughts and suggestions on this guys.....

The ZZ is not rated to 140kg that may be it's safe working load with a hefty safety margin, or even a rating given for smooth function.

In the event of an aerial rescue you should be fine (not tested it myself) also note most kit is only rated to one person as stated in your loler, so after any event that exceeds that your should have it checked over.

[andymum]

yer i understand that and that everything can take more than stated by manufacturer, zz is maximum working load 140 kg/one person rated taken from inst manual with product.

 

But with that in mind would it not be prudent to back it up or overide zz with a pruss

Give it a go sometime, get some bromance going with another climber get him to attach to you and weight your system whilst he is still on his slack system as back up, and descend, just to see how it feels. If your confident in the test then no need to worry, nothing bad should happen if there is 180kgs on it for a short time during rescue, and I'd rather the quickest least messing around with extra Prussik rope option. Aerial rescues of this nature are pretty rare but it doesn't hurt to be prepared.

yes i agree bud that's why we practice this quarterly. but have also emailed petzl direct and there uk spokes people for there opinion. No question if required for real no messing about, just wana be sure practice ones wont damage zz also

[DrewB]

i think just looking at the ZZ wrongly can damage it..

[Arran Turner]

Im not sure if a spiderjack has a weight limit but I've practiced rescuing on one and it descends super fast. Agreeing with mark as in the case of a real rescue you will get him/her down regardless. breif exposure to say 180kg isn't the end of the world in my eyes.

Yeah a rescue on a spiderjack gets you on the ground pretty quickly, requires a fair bit of thumb strength to maintain control but it's alright. You could always put a figure 8 in underneath the zz like you do with a hitchclimber? Test it out.

[colemanjessenz]

if you are worried mate just add some friction to the system via an 8 or rope wrench or even munter hitch.

in comps the spider jack and lockjack can be used with two people on one system but can't say for sure with the zig zag.

[andymum]

easiest system so far is a pruss above as a fig 8 would have to be two handed leaving no had free for cas

still waiting for a reply from petzl
