worn out portawrap 3

[Stihlmadd]

I'll have to just to stay right in the head!

if you were right in the head why would you be doing this job in the first place?

 

[Stihlmadd]

What do you mean 70? If Stihl' quits smoking he'll just be hitting his stride about then.

yeh struggling there won't lie not a easy takedown that bugger nicotine, but my grandpa is 94 still smoking and a half pint of stout every day so there is always hope.

 

[Stihlmadd]

Save that porty, that is a testament to how much work you have got done with it. when your 70 and no longer climbing, you will appreciate it I bet!!

for sure I will need something to comfort me while the nice nurse tends to my aliments

Here's the image of the two Porty 3's side by side, 1 aluminum and 1 Powder coated, both large.
I only use the aluminum version as a demo to anchor it to a tree. Not for actual lowering.

Norm your ally portawrap is showing the same wear pattern in the same place, what dia' ropes have been run through it?.
I have been using 12 strand 16mm and 19mm bullrigger from sherrill.

Mostly 1/2" (13mm) 3 strand. But some 9/16's and 5/8" double braid too. I would say about 60% 3 strand and the rest DB.

 

[Stihlmadd]

I moved away from three strand due to hocking it may have been the particular rope we were using at the time.
most work was done with the 19mm/ 3/4" which I believe accelerated the wear due to the extra surface area and the way that bullrigger will square off as it ages.
I once melted 13mm 1/2" double estaron to the portawrap and went away from those style of rope materials after that particular incident.

 

[Norm_Hall]

Yeah, I only used up to 5/8" ropes on the aluminum. The steel powder coated gets the 3/4" DB ropes. Like said in a previous post, the aluminum doesn't get used at all anymore. Use the steel powder coat for everythng now.
I know I'm the minority, but I still really like using 1/2" 3 strand. The brand I use doesn't hockle as much as others. Don't wanna mention brand names. It becomes a urinating match. Everyone has their favorites.
My old employer had a large steel Porty 3 that had a True Blue rope melted to it. The crew told me they had to use a slotted screw driver to pry the rope off of the Porty.

clean your ropes!
Its the dirt and grit t

Daniel it has been bugging me for a while now that I did not get back to you about the dirt / ropes.
I do semi-regularly clean both my climbing and rigging ropes combing with a mandatory use of rope bags for all the kinds I own.
I do agree with you that ropes build up dirt trapped in the weave and twist and this is abrasive , one of the reasons I agree with this is I have seen over the years the difference between metal on metal contact and rope on metal contact erosion.

I also make it a practice to replace the ropes every year to 18 months after initial use and store all my kit in dry aired places.
you could say I am a bit fussy about my gear stowing , only have to look at some of my photos to see that.
anyways again my apologies for the delay.
Ben.

no worries... good thread!

Despite my comment following Daniel's post I am also a fastidious rope washer. Woolite works well, PMI rope soap works best IMHO. The emulsifier is not a petroleum distillate, which will ultimately degrade poly ropes with repeated washing. I use only double braids and have concerns even after washing that abrasive grit works its way through the out jacket during elongation and into the core. I usually try to get two years out of rigging ropes. I've never come close to the kind of wear visible on Ben's porty, though I have managed to wear the anodizing off of a portion of some of my XRRs .

This is correct, from talking to a couple of the rope manufacturers. Another good product is Zum Clean laundry soap. Also without detergents or petroleum products. I find it at HyVee grocery stores and a lot of other places that sell organic food/products. No bleaches or anything else nasty in it. Coconut oil based stuff. Smells wonderful.

 

[Stihlmadd]

I only use organic based liquid wash.
also have a spindle free top loaded LG washing machine which is very gentle on the ropes.

...also have a spindle free top loaded LG washing machine which is very gentle on the ropes...

Yeah, that's the type I have... not an LG brand, but big stainless steel tub with no agitator up the middle. Love that thing. Can wash a couple of ropes at once.

Anyone know if Oxyclean is safe for ropes?

 

[Gorman]

Doctor Bronner's!

 

[JeffGu]

Anyone know if Oxyclean is safe for ropes?

Most detergent products that clean "with the power of oxygen" contain peroxides (which are bleaches) and therefore are probably not a good idea for the ropes.

 

[Boomslang]

I did some research and found the active ingredients in Oxiclean are hydrogen peroxide and sodium carbonate. My ropes are all polyester and according to the chart here: http://www.engineeringtoolbox.com/chemical-resistance-polyester-d_784.html polyester is resistant to both of these chemicals. I also swiped this chart from Marlow ropes showing polyester does not lose any strength when exposed to hydrogen peroxide.



Not saying Oxiclean is 100% safe, but I've found no reasons to believe it's unsafe, at least on all polyester ropes.

I clearly have to much free time, back to your regularly scheduled programming.

ahh but you invest it so well sir!

 

[JeffGu]

Very good... I stand corrected! I still suspect that the peroxide will fade the nice, bright colors of the ropes to something a bit pastel... suppose I could dip the end of a rope in it and see.
Either way, I prefer using something a bit milder in temperament. Not just for the rope, but for where it all ends up when it gets done traveling down the drain.

Resistant to carbon tetrachloride, even... unfortunetly, humans are not resistant to it. Interesting info on that chart!
