twisted cable

I wonder if the end of a rotation resistant rope wasn't annealed properly and the outer and inner rope separated, letting the outer rope to deform. I don't know what happened for sure but all you would see of me would be the back of my crane heading down the road to my crane shop for a new rope. A few hundred bucks to finish the job ain't worth risking killing someone when that rope fails.
 
Spooky.

BTW, farmers love old crane wire rope for fencing and other ranch uses, I've even sold it in the local ag paper.

I also gave away several of my slings this year, some as Christmas presents, (!) that I deemed less then perfect but still darn good for tow straps. Having a good second use for both items makes me feel better about buying new.
 
the stock cable on out manitex 38124s had a problem a few months after we bought it, looked similar to that except not as bad, I think it was a 35x7 rot. resistant but it was a while ago, anyway the manufacturer of the cable didn't spin the strands tight enough, or spun the entire cable too tight or something like that, anyway it was too tight for one of the outer strands and forced it out, it gave the cable that same spiral look. still have that reel of almost brand new garbage cable lying around somewhere.

I feel the same way about getting some use out of the rigging taken out of service and did the same as you until I heard about some one doing the same and was sued and lost by some one that found one of his slings and used it in an unsafe manner, with serious consequences. Now I cut the ends off wire rope slings and synthetic slings and deposit in the trash, hurts a little but it won't come back and bite me in the ass.

“pigtail” or severe spiralling in rope.
• Check that the sheave and drum diameter is large enough. Bridon recommends a
minimum ratio of the drum/sheave to nominal rope diameter of 18:1.
• Indicates that the rope has run over a small radius or sharp edge.
• Check to see if the rope has “jumped off” a sheave and has run over a shaft.

I am researching a new hoist line for my crane and my research has led me to Bridon, I copied the above out of there spec. pages today
 
found this as well

Wave or corkscrew deformations normally associated with
rotation-resistant ropes.
• Check sheave and drum groove radii using sheave gauge to ensure that they are no
smaller than nominal rope radius +2.5%. Bridon recommends that the sheave/drum
groove radii are checked prior to any rope installation.
• Repair or replace drum/sheaves if necessary.
• Check fleet angles in the reeving system — a fleet angle in excess of 1.5 degrees
may cause distortion (see page 44)
• Check that rope end has been secured in accordance with manufacturer's
instructions (see page 56 and 57).
• Check operating conditions for induced turn.

Wow, must be a lot of lawyers where you are at! The day I cut up my old rigging instead of giving them to someone for a tow strap or whatever, will be the day I stay home in bed with the covers up over my head. I'm in Idaho, and the people I choose to gift with my old rigging I am pretty sure won't sue me if it fails pulling their truck out of a ditch. That's just nuts to my way of thinking and not the way we still do things out here. NOT to say, sadly, you are incorrect in doing so, I just refuse to go that route. Screw 'em, sue away, I have better things to worry about. Maybe I'll have them sign a release, ha ha.

Yup
Even if you win, you'll loose the money you'll have to spend defending yourself.
It shouldn't have to cost ya to be a "nice guy", but unfortunately that is the way our society is going.
 
I don't want to sound all paranoid , truth is if I shouldn't be using them,no one else should be either. If they are cut up I won't be temped to use them either "Maybe I'll use those old slings on these concrete forms cause there hard on good slings"
