Possible zigzag accident

[Tom Dunlap]

A rule of thumb for pulling power using a horizontal line and good traction is about 60% of body weight. Do the math, it might take more than two people to generate that pull.

Now...a shock load is different. That's why we bounce test PSPs and TIPs before climbing.

Bonner, I grabed this from the wesspur site. I feel that the distrubtors in the USA need to clearly label gear that DOSE NOT MEET ANSI specs. Much like they do for screw gate carabiners. Most of gear is made in the EU and to their standards not our, and there for should not be used for WORK in the US...

Wish I would have know this before I bought mine.

Yeah I read that crap in some article and we brought a dear scale in the next day and everyone at the shop tried it, we were all able to pull way over that without feet placed. With feet chocked it was FAR past 60% of body weight.

I am not sure what ANSI requirements we are discussing in relation to saddles. Here are all 3 pages of the 2012 Z133 that reference arborist equipment. The only part thats relevant to a sequoia probly is 8.1.12

Dave, a quick read of the Z133 shows that the 5000lb requirement only applies to ropes, biners, snaps and screwlinks. There is a hole that mechanical hitches/friction devices, and saddles fall right into. I can share a digital copy with you if you need it.

Pretty disappointing though, like you, I cant imagine making climbing hardware with break ratings below 23kn.

Thanks Nick.
Comprehending that tensile strength hole is a little above my pay grade and tired brain right now. If something meets European CE Standards, but is rated less than ANSI Z133, is it legit to provide an employee with it?

 

[bonner1040]

In Europe it is. But not in the USA. However there is no standard for harness or mechanical work positioning tools, static or dynamic.

 

[Tom Dunlap]

Currently, and for many years now, there is NO ANSI Standard for work positioning harnesses. The is for fall arrest though. The ANSI harness committee let the Standard lapse many years ago and it hasn't been revived.

There is a group of good people working on writing a new Standard for work positioning. For years the manufacturers have used the former ANSI WP Standard as their guideline for building harnesses. Since some of the US manufacturers sell in Europe they've built to those specs along the way.

Just what is this?

Looks like 8mm OP.. but I'm not familiar with that splice on it......

Any info would be appreciated....


Couldn't load the attachment.. it's up on the last page.. looks like an Eye and Eye....(Green cord w/ shrinkwrap ends) But as I know 8mm OP... it's a class 1 double braid splice..

I'd love to know just what THAT is!

 

[ChuckR]

Can't see the attachment, Mark.

 

[markprz]

attachment fixed!

Probably 6mm Ocean Vectran.

 

[oceans]

It looks like 8mm OP without the core in the eyes. Looks like something "tuttle" made. He kicks around on the Splice Rack.

 

[tuttle]

Hi folks.

Its 8mm ocean polyester, the core is removed and put in the bin, the core is then replaced with 6mm v12 vectran armor coated with an mbs of 3350kgs, its brummeled and lockstitched, then shrinkwrapped.

My design, only a few remaining. Just started making them with armor prus as the cover.

[bonner1040]

Why did you use Validtor12? I am just curious.

 

[DBT]

would love to see that pass a gear check/loler- " so yeah, i removed the core but trust me, its all good" whats the point ? not having a go bro, honestly but the ability to confuse is large.

 

[bonner1040]

Validator 12 is one of the single strongest, highest quality, most heat/wear resistant materials out there. Its also extremely expensive.

It has higher strength than Amsteel and better heat resistance than Tenex.

Because i'm a 'Rope Doctor' and one day things will be great.

 

[markprz]

That's why I asked.....

Tuttle... rope and rope technology is changing so fast.. what do you think you are doing? Creating life support from bits and pieces.... Your 'frankenhitch' is not something to be promoted and sold... with out thoughtful and complete testing.....

If you're doing that with materials from different ropes... what ELSE are you doing?....

Pardon me.. but GTFA from me with that...

I'm fully qualified tree surgeon, worked in several industries, plenty of people go on about 'its a piece of rope don't mess with it' lack of knowledge that be.

Its not bits and pieces, I make hundreds, and know all the textiles, threads and fabrics across several industries.

 

[markprz]

Good for you.....
Do you have a website?
Do you have a CV?
Do you share your identity or company info?
Do you have insurance?

I looked at your ebay page... no info.
Do you do any testing?
Do you share results?

I'm a fully qualified tree care expert too....
I know lots of stuff too...
I also know that that doesnt't amount to a hill of beans
When it comes to product liability for life-support items.

I don't see you or your 'products' as legit.
But again.. that's just my opinion....
