Wire Rope Swage Straightness

[BMart006]

Is there an industry standard for straightness of a swaged wire rope termination? We have a termination for a crane's whip block that was made with a visible angle, but I was wondering if anyone has run in to this before and if there are established acceptance criteria. Thanks

BMart006:
A couple photos from different orientations would really be helpful in making some judgement. It’s the old, how much is too much question; 2 degrees is o.k., but 2.5 degrees isn’t, who says? I’m not sure that I would expect to find some world wide std., but I’ll bet the people who supply the rope and the fittings have instruction/stds. sheets which give some advice and instruction, and some do’s and don’ts. But then, you also know one when you see one, it sounds like sloppy workmanship. Have them cut off the end fitting and replace it. The most important thing probably is that the end fitting not excessively load the wire rope in bending when it comes into play, assuming that the swagging is good otherwise. Call a couple fitting and rope suppliers and ask their advice, they want to protect both your’s and their equipment.

Some instructions for rotary hammer swaging, require, that a small kink be put into the wire to hold the fitting in place at the start of the swaging operation. That kink in the wire should be halfway down the length of the barrel of the swage, and disappears when the swage operation is complete. If you have a visible kink in the wire when the operation is done. The first thing you should do is inspect the terminal to ensure the fitting did not move during the swage operation.

You are judged not by what you know, but by what you can do.

Crosby Group catalog depicts a variety of wire rope swages. You can go online for a direct viewing of their current catalog. Perhaps, dimensional tolerances are described. Personally, I would replace the one with a Crosby product. Remember swage fittings have a strength of at least the strength of the wire rope and in your case you may not be able to meet that wire rope strength. A bent swage fitting will eventually abrade and weaken the wire rope therefore it is not worth the saving of your defective item.
