Rigging pulleys

[TDunk]

I'm starting to get into more technical take downs and am looking at getting a 3/4" pulley, but i don't really know how heavy duty of a pulley i need. CMI makes one rated at 8,000 lb. work load (witch is what i'm leaning towards) but is a little more than what i wanted to spend. And ISC makes one rated at 4400 lb. work load, witch should be more than enough for all the more i do, but i also don't want to buy the cheaper one and find out that i wasted my money. Any advice would be great.

If you do not have much rigging gear go ahead and get the one you can afford and work with it until you can buy more rigging gear. For the most part, you will get years and years out of the hardware if used properly. If you have to get the smaller pulley then you may have to take smaller pieces for awhile. Eventually, you will need both plus some smaller ones. I rarely use my big pulley for rigging but it is nice knowing it is there to use.

Use a shckle on heavy duty sling and you can save money and forget the block...

It works fine, as I;ve seen and heard from others... doing major takedowns. I've been meaning to go that direction too...

I use a clevis shackle for light rigging, it works pretty good... But for heavy blocking the tight bend in the rope is less than ideal.

Agreed. Everyone needs a good heavy block for blocking down wood. I use the Yellow ISC for real heavy and White ISC for a little less heavy. But for light rigging a caribiner or rope snap on a sling is more easily used than a shackle. I dont care for the small micro pulleys for rigging, krabs are the way to go.

sometimes you say the darndest things. I could see how it closes the gap when blocking down BUT not with my rope.

I do use this method to but not really pushing things with it

I am sure some ropes would work better with just using a shackle; What would you use? My ropes are stable braid for heavy and 1/2 16 strand for not-heavy. I would hate to go mung up that stable braid. Amsteel? tenex?


there is actually stable braid going through that shackle there, the other ropes were, well, all tied up. It cause more severe milking on that.

A screw pin can be twisted out of the shackle by a rope. Not a nice thought. Use a decent block, thats what they are made for, shackles are not right.

I disagree. It might be better to spend the extra ( its not a whole lot more) and get the biggest they got first thing. Then you know you are covered and it can do both little and big. sometimes taking smaller is more dangerous than sending the whole thing out.

100 bucks for a pulley is great compared to what other things go for.

And another good reason however the shackle I used for crane work has a through bolt and a safety pin. But still...

Who the heck is Manny? You should post pics of all this stuff you got tom, we are missing out and its not fair. Besides then you wouldn't have to type at all.

I just went with the CMI block with the 8,000 Lb. working load. I was not to thrilled about the $200 tag from Baileys so i did some shopping around and found the same thing (from a non AS sponsor) for $139 and free shipping, so i think i did ok. Thanks for all the help.

Yup.

Max Working Strain would refer to the "shockload" syndrome or if you were to anchor it at a set hard point and the sheer power it would take to officially rip the thing in two.....I believe...

Nah, that was a typo. Should read 11 ton. 22,000 lbs.

I prefer the ISC spring block, no parts that will drop out of my hands.
