Porta Wrap Question

[PTS]

Today we were doing a couple removals on Red Oaks. We are using a new rope that we bought from a neighboring tree service (NEW) who deals in climbing and rigging gear. I told them I wanted 2 150 footers for rigging with a porta wrap. They sold us a three spiral white in color rope and the guy working was told by the owner that it was what we were coming to pick up but the kid didn't know the name of it and the owner was no where around. Looks like the same stuff in the Sherrill Catalog.

Anyway, while roping chunks of log only about 300-400 pounds down using the pora wrap to a large block pulley to the log we had the rope melt itself to the pora wrap. Never seen anything like it before. SO I don't know if we are doing something wrong or if it is the new rope. Anyone else run into this or have any thoughts?

WOW.........i can't say if you did anything wrong with out knowing how you had the rope fed through the porty. but my guess is that's some funky rope you were sold. i've seen many a rope burn fron natural crotch rigging, but i've never seen a rope burn on a porty.

how fast were you trying to lower the stuff?

I wrapped it and it was wrapped to specs. I only used two wraps and was working on showing some groundsmen how to let it run. good example it was. It locked it self out so it appear until I found that it melted to a stop.

next time I suggest buying a real rope. One with a name and a label and a tag with max load and working load. Sounds like you got some Home Depot 3 strand special. What's the load rating on it? What's it made of? Polyester? Nylon? polypropelene?

"It looks like a strong rope" isn't good enough for me. I need to know the max load and working load of every rope I use, and I mentally estimate the load I'm about to put on that rope before making my cut. IMO the rope is a tiedown rope for your trailer unless you know the load ratings.

Don't buy ropes from guys selling them out of the trunk of a car. Sounds like some cheap poly rope used for tieing up boats. I like my ropes to come in a bag or off a spool that has a brand label and load rating on it. Glad no one got hurt and lucky no damage occured, but in the future I would avoid the deals and buy from a reputable source. To much at risk to take a chance like that, Be careful.

My guess would be that it is polyester. I had one fuse a bowline on a bight together when pulling a load of brush off a trailer.

This rope was bought from Karl Kuemmling Arborist Supply by this other tree company and then resold to me new. Doesn't mean that it is a good rope but I know it had a tag on it with the name.

bummer about the bunk rope. shouldn't have melted to a stop, I've seen them glaze on a lowering device but never melt to a stop, cut your losses and retire it to a handline/ and or utility line , or find out what you bought exactly and get your money back if it was mis represented.

 

[RedlineIt]

Cool!

Rope that self-brakes on a run! All rigging rope should do this, just think of the savings on gloves!

Look on the bright side, PTS: you now have one 150' and one 150' minus whatever tag lines.

So what did you pay for 300' of this rope of unknown dynamics? I'm guessing you got what you paid for.

we bought several things that day but if I remember correctly it was around a hundred dollars per 150.

The seller has yet to return my phone calls. What does that tell you?????

Sounds like you got the shaft on that one. One other thing that I would like to mention. 3 strand rope kinda sucks when using a portie. The three strand construction will cause the tail end of the rope behind the portie to twist up and bunch up and it is fed through the portie, causing a serious rats nest if you arent paying attention. I have even heard of this happening when a groundie was swing lowering a big chunk into the yard. No big deal, just let the chunk swing free of the house and over the lawn and let go of the rope and it should plop down safely on the lawn. Any who the chunk swang over the lawn, the groundie let go of the rope fell about 10 ft and then all the twists and coils got stuck at the portie and ye old big chunk did a nice pendulem swing into the bay window. Just some food for though.

Yeah I found that out. I have a braided one that I like to use but it is getting short as we have robbed some chunks off of it. Where we were working was a free fall tree but I wanted to do some training on it and unfortunately didn't have what I needed in the truck. BUT I guess the good thing is I found out my rope sucks before I cause the Above example of my own.

 

[OutOnaLimb]

Try the Samson Stable Braid. Thats about the best line going. Even the stable braid has a tendency to twis and coil to some extend, and after it breaks in the sheath streatches out a little longer than the core, but all ya gotta do is cut off one end and milk the cover down cut it to the same length as the core and re whip and melt it and your good to go.

you need to do a midnight dump run in that guys driveway- a load of biscuits should do

 

[PTS]

The place is such a dump I don't think they would notice.

 

[John Paul Sanborn]

I've had ropes melt, or throw off skins of plastic from too few wraps and to fast a run.

Another way it can go wron is if you do not have the wraps in tight and a few stransd of one wroap get caught in the adjacent wrap, this can cause a big chunk to melt as the hot plastic adds more friction.

 

[Redbull]

Kyle, I have 150' of Stable Braid you can check out when you come to town. I only use it when using pulleys and a PAW. No natural rigging allowed with that rope. Three strand and 12 strand is best for natural crotches.

The distributer's name given above has a typo, which thank-you Google should
be "Karl Kuemmerling Arborist Supply" whose rope products can be seen at
(what a I love about the WWWeb--who could guess a phone number? --but URL?!!)
www.karlkuemmerling.com/prod23.htm

Perhaps you have the "3-Strand Bull Rope Combo", which I take to be some blend
of PES & PP--and PP has a low melting point (though in many combo/Poly-Dac ropes
is shielded from frictional heat by being core material only).

"sounds like polyester"?? PES melts about same as nylon, so what would you ever be
using that didN'T, in that Bowline-on-Bight case? --Vectran, Kevlar, Technora, PBO (!!)?!

rope

Today we were doing a couple removals on Red Oaks. We are using a new rope that we bought from a neighboring tree service (NEW) who deals in climbing and rigging gear. I told them I wanted 2 150 footers for rigging with a porta wrap. They sold us a three spiral white in color rope and the guy working was told by the owner that it was what we were coming to pick up but the kid didn't know the name of it and the owner was no where around. Looks like the same stuff in the Sherrill Catalog.

Never seen anything like it before. SO I don't know if we are doing something wrong or if it is the new rope. Anyone else run into this or have any thoughts?

be happy this rope didnt fail and send a piece into your guys or whatever you were trying to protect. the seller is probally an inhouse dealer for his guys only. must be a fairly large company, if not/ bring junk back, get money back, buy new rope from wesspur( they have crazy strong ropes), it could have been a freebie prototype that you got sold, when you are a dealer ya get them free stuffs to try and report on . your report should read get money back immediatly! his agreement with the manufacturers should be exclusive to in house crews only, because there is a dealer that has your territory, if on the other hand he has decided to sell to the public as well as being tree service... acting as a dealer or another branch of karl kummerling demand money back! kummerling is an ancient company that will back their gear, you were there and you wrapped it yourself. If the shlickster is stil playing hard to get mention on a message that you need to get to the manufacturer for a recall of the rope spool, hopefully this will produce some results. oh for heavensakes no more ropes purchased with out knowing breaking strength, safe working load, shock load on the application the rope is being purchased for. And the Brand so you can compare notes on this site.
