What's a good type of pulling rope for pulling from 3/0's-500's?

MDShunk

Round.

I only have three sizes of rope, and they each have different stress ratings. I run the pull calc to see what size to use (or, more often, use my gut). The wire size is a factor, but so is number of bends, length, type of pipe, type of insulation, type of lube, and direction you're pulling.

1/2, 9/16, and 3/4 are the most common sizes I've found useful. If you're puzzling on buying just one size of pull rope, buy 3/4. Murphy's law, though.... you'll probably need something bigger the first time you need to setup a big pull.

Ok, so that's just round nylon?

Um a big one!! No just kidding, kern mantle rope ( outer nylon sheath with cords in the middle) at 1/2" is good for about 5000 lbs. Weaved rope at1/2" is good for around 7000lbs. Bet bet is get a good kern mantel at 3/4" , that will pull a house and if you factor in bends and weight of the wire it will be worth it. Remember if you stress a rope too small its not rated for full weight any more. Static rope is what I like for pulls, static rope has no stretch, dynamic rope has stretch. If you get a dynamic rope what I usually do is tie it between two cars or trucks and pull the dynamic out of it! Not recommended but if no choice then do what you have to do.

Weaved rope also burns the crap out if PVC bends that why kern mantel is best. Kern mantel is also cheaper and is waayyy more plyable.

There's nothing like rotten mildew smell of a spool of pull rope that's sat outdoors in the rain.

Water and mildew kills any rope.....if you can when you buy a rope take it to a laundromat and buy a bottle of dry treat for rope and wash in drytreat. It will repel water for about a year and makes it wicked slick and plyable. You can buy the treatment at an EMS or similar store. Works wicked pissah!

I'd have a rough time getting 600 and 1200 foot lengths of rope in even a very large washing machine, I think.

In an industrial washer you can put about 1000' of 3/4 rope. But you have to watch it. The other method for larger ropes is you soak it with drytreat in the tub, but you have to wear rubber gloves when dealing with it. The trick is to use a front loading washer, I destroyed a top loading washer a few years back trying to treat a climbing rope. My wife was super pissed about that one but she got what she wanted in the end and I lost a good rope to the washer!! Got all screwed up in the drum and now its lashing rope now.

I like nylon weaved rope primarily so that I can weave a new eyelet/head onto it if I have to. Happens quite a bit on the smaller rope, haven't had to do it on any of the larger sizes.

MDShunk

I think all mine are double braided ropes. They sorta have a jacket woven over top of the actual rope inside. Not sure the technical term for it.

Thats technically a kern mantel rope. Outer sheath with internal core and the internals are woven. The sheath is for protection and the internals carry the weight. The crucial part is to keep all the crap that ropes go through from getting into to core because the core threads are way sensitive to breakdown. I could go on for hours about rope care but from things I've seen most guys just roll it up wet and full of wire lube( which is mostly soap) and you don't know you have a problem until "you have a problem"!! Again how much stress does a rope take? Well you don't know until it breaks and it leaves you stuck, weather that be on a mountainside or a wire pull its still a piece of equipment that I feel gets overlooked by most guys in the trade.

Its a chunk of rope, use it hard and when it is beat get a new one.

Labor costs to much to treat a pulling rope like it is gold.

We use 12mm polypropylene rope in 200m lengths that we hand coil into those heavy blue polypropylene water drums with the lids cut off. Anybody else know how to splice rope? I got a knot tying book one Christmas that showed it and I'm addicted to it, its a great way to relax, I'm weird like that.

Do you guys ever run in a proving pig before you pull?

BBQ

That is like using a bungee cord.

Sometimes the job specs require a mandrel be pulled through and witnessed by an owner or engineers rep.

chewy

Only the first few times then she breaks in nice

TimChaput69

Sorry BBQ but when your pulling 500's over 300' and the rope breaks at about 150' its all your show! Don't have to treat it like gold just can't treat it crap cause rope is made of organic material except for nylon rope and that stuff is crap. Oh by the way have you priced rope out lately? Just a silly 180M rope costs about $200. A spool of 500' 5/8 rope is around $1000 and thats just personal and rescue use, never mind industrial use....you must have done really well at the casino if you don't care about money!!

TimChaput69

That sounds like a 5/8 rope. There really is no way to "splice" a rope. What you do is use a sheeps bend. Take the damaged part and make a loop then in the working part of the rope tie the knot into the rope, you can't pass that section through and device after though because it will hang on everything.
