I just added the tensile strengths.

Don't mix up the rope you climb on with the rope you pull stumps with, not a good idea. Your life depends on your climbing line being in good shape. The dynamic loads you put on your pulling rope weaken it and it's not easy to tell when you overload it too much and tear it up inside. Keep one rope to climb on seperate from all the ropes you use to do other things. Inspect your ropes every time you use them.

Gotcha...

Ah, much better.

Mike, trust me- I'll never own another frigging Mopar again.

Something for you guys to consider when talking about loading ropes- we have more experience to discern what can/can't be done.

No offense to Jay, but remember he IS new to this.


Also, I thought we selected our ropes based on SAFE WORKING LOAD, not TENSILE STRENGTH. Did this change overnight?

After all, you don't see anyone climbing on Zing-It, do you?

jaymay75,
If at all possible, take a weekend course (if one is available to you...tech school, arbormaster, etc.) You might dish out some cash, but what you will learn will outweigh the costs involved. If nothing else, make that drive over to philly and spend a day or two w/ bigjohn. I don't know him personally, but he seems to have the hang of this treework thing!
One thing is for sure do not ever be afraid to spend a little extra $$ for decent equip. or a little education.

You can select your ropes on either. Personally, I perfer breaking strength, because you don't always know what safety ratio is being applied, when somebody else calculates working loads. I prefer to determine my own safety factors.
If you are putting 4000 pound loads on a rope, it should be bigger than 1/2". You must apply the same logic to the come-a-long too. A two ton come-a-long has a 4000 pound breaking strength and is a good match with a 1/2" rope. I've pulled on cheapo come-a-longs too hard and broke them with 1/2" rope a few times. So in that combination (1/2" rope and 2 ton come-a-long), I'd say the come-a-long is the weak link.
I'll usually take the tail of the rope and bypass the come-a-long and secure it to the anchor, in case the thing fails.

i........,

i........,

o heck, i........ agree with Mike

i'd personally make my own safety ratio, and would like the raw tensile.

A new-b(udd)ie; might find SWL recomendations more pratical, but should realize some set different ratios than others; sometimes making comparisons between devices a little more foggier; especially grabbing things from different industries etc.

Or something like that

And i look for Minimum Breaking Strength, ves Average. There can be a over 1/4 ton differanced between mbs and abs.

 

[MasterBlaster]

The most expensive usually turns out to be the best.



I hate the Fly...

 

[BigJohn]

Why do you hate the fly? The rigging I do with it is setting up a 16:1 set up. I don't know how it works with a tautline hitch.

 

[MasterBlaster]

My hitch has nothing to do with it. The soft-lay properties of the Fly tend towards making the rope come alive and catching/tangling on any little piece of brush on the ground.

Great if I was spelunking, bad for treework.

Gimme a 'lil harder lay, like my trusty Safety Blue.

 

[BigJohn]

Butch sounds like you need to review your groundman sheets with the crew. I forget isn't something on there about keeping the rope clear and no bellies in the rope? Dude you need to get them boys in check. For me I like the soft lay of the fly.

Anyone have any experience with Tree Pro red?

I used one for 6 or 7 yrs. Loved it. It was still in decent shape but retired it because of age. I was using tautline then though. I haven't tried it with a VT yet. I would like to know if anyone uses it with an advanced hitch? I use the company hi-vee now. It seems to have too much stretch for me.

ropes

I invited Jay75 over, so I'll see Jaymay75 tomorrow morning and give him a hank of Blue Streak and maybe a hank of Safety Blue to try out. I can at least get him on to some 1/2" rope. I think he'll need heavier rope for the winch but it will give me a chance to show/give him the ropes and talk. I think if he sticks around and reads this site he'll learn a lot about how to avoid the Darwin Award.

 

[Stumper]

Mike Maas, Every now and then you post something completely reasonable. On these occassions when you behave totally out of your normal character I agree with you and am overcome with awe at your great intellect and perspicuity.

 

[geofore]

looking?

I got a coil of Blue Streak & a coil of Safety Blue on Tuesday and have a bit left over. I offered RAH a hank and my buddy Jim needs a hank and I have enough to give Jay75 a hank and that's it for the new rope cause I need the rest of it for my use. I broke one of Rich's ropes last week so I need to give him a replacement. Jim set up a shop for me in Butler so I don't need to take any equipment except my saddle with me when I go up to Butler, he will now have everything I need at his place, he also has lined up work. Then Jay75, he needs some one to show him the ropes. Will it lead to work or not? Don't know, but it doesn't hurt to help the new guys out. Someone got me started years ago, so I pass it on.

 

[Kneejerk Bombas]

Hey GEo, how'd you bust a rope? I mean, what ******* thing did'ja do wrong?

 

[My like trees]

Nice post Mike, right, *******, breaking a rope? Thats what happens some times. Mike I hope your joking cause that is some low end jive.

 

[My like trees]

I geuss Big John does not like arbour plex. If only you used it you might know its prety ???? good IF YOU KNOW HOW TO USEIT!!!!!!!!!!!!!!!!! I could use that poly ???? if i had to but I don't. Get the job done, thats what its all about. Its not the only rope but test after test tells me its OKAY! Whats better than actual testing?

 

[rumination]

Yo, jive turkey! (That's right, you know who I'm talking to) Now you be the one spreadin the bad vibes. Chill out, yo! :angel:
