Lol, ya you guys can swing all you want 70-100 ft up there, and while your swinging you can think about that pic.

Reduncnacy is such a bitch....enjoy.

Some of the macho idiots onn this site are just that...macho idiots.

Enjoy your ZigZags, and be sure to keep an eye on your parts, you just never know when plastic is going to go pop.

 

 

Have you even seen a ZZ?????

I think he's drunk

I thought all life support equipment had to be a minimum of 24 Kn breaking strain.? If the zz splice attachment point is taking half the load (reported to have been loaded at 15 Kn for 3 minutes) and the friction plates are taking the other half of the load (presumably 15Kn) does that not mean the bridge attachment point should be 30 Kn? The zz tested today failed at 15.6 Kn at the bridge attachment attachment point. I think the rough math for a climber falling is your (the) weight doubles with every meter fallen..

 

 

Ie. My weight 87 kg falls one meter = 87 X 2 = 174 kg

174 kg falls two meters = 174 X 2 = 348 kg

348 kg falls three meters = 348 X 2 = 696 Kg

696 kg falls four meters = 696 X 2= 1393 or almost 14 Kn..

 

Theoretically, If an 87 kg climber fell 4-5 metres onto a slack system whilst climbing on the zz you can't expect it to save you. (If you fall 4 meters onto a slack system the zz would be the least of your problems)

 

Rant over...

 

This Maths lesson was bought to you by Macho man Randy Savage.

Thing is, reading the report again, he didn't actually fall on a slack system.

I'm worried about the integrity of my Vertex Vent now.

I'm considering wearing a hollowed out pumpkin instead today just to be on the safe side.

Imo that's worse. If it failed from slight jolting what would it do in a decent fall? I can't see how a side loaded crab would rip the splice attachment point off and the d attachment point failing at 15.6 is enough for me to be back on a hitch.. At least for now anyway..

A fall exerting 15kn on the zz eye (30kn on the anchor point & climber) would do so much internal damage that gear failure would be the least of your worries
