Re: [WISPA] Help identifying this shackle
Not sure if the block should be curved like that. I would look at getting an equalizer plate if possible.

From the bend in the bolt, that is the right answer, I think. On 9/16/2013 2:36 PM, Cameron Crum wrote: Why not use a load spreader instead?

Re: [WISPA] Help identifying this shackle
LaRoy, This is obviously the wrong part for the application. I personally would be more concerned about the depth and proper construction of the anchorage point. The correct way would have been a leg anchor with a dispersion plate at the end. The turnbuckles should have been eye bolt style with the blot ends mounted through the plates. Too late for that now With what you have in place I would just replace the shackle with another with a much greater load rating. Without knowing the tower model, height, loading and physical location its only a guess. But watch out. There is a ton of cheap Chinese crap on the market that, while rated for a certain load, has failed under much less considerations. Spend the money and get shackles from Crosby. They don't play games. The turnbuckles should also have security ties in place to prevent the turnbuckle from being adjusted and in case the TB should fail. I also wonder what the guy strand is coming out of the anchor point.

Re: [WISPA] Help identifying this shackle
I had never seen anything like this until this tower installation about 15 years ago. I thought the bolt was bent the first time I saw it but I really think they are made that way. The tower is 190' with 2 sets of guys, and inner and an outer set and all 6 shackles are this way. A couple of years ago I ran across this same shackle somewhere on the internet and that is when I realized they are made this way. I wanted to find it again just to read up about it. I have to replace 3 turnbuckles at one anchor point due to someone hitting it with a bushhog. I really don't know how the tower is still standing. All guy wires have so much slack you can swing them in circles like a jump rope. I guess Rohn 25 towers are really strong, this one is almost free standing :).

You could use an equalizer plate or since you already have an anchor with space for 3 guy wires, just use a short piece of guy wire to connect each turnbuckle to the anchor.

Re: [WISPA] Help identifying this shackle
I did not make myself clear about the guy wires. There are 6 total sets of guy wires on the tower. The bottom 3 sets are at around 50-70' from the tower and the top 3 sets of guy wires are at a much greater distance from the tower. I am with you about the way it should have been done vs the way it was done. The good turnbuckles do have a loop of cable thru them to keep them from turning and the one set that got hit used to have a loop. It will require some TLC to get back in shape but I have see worse.

Amazingly 25G is extremely resilient to falling. There are several videos on the web of guys dropping these towers and they continue to stand after all the guys are cut. Sounds like you have a tower that was installed in the just wing it format. That's alot of 25/45/55G towers..
