(Sigh) What can I say that this picture doesn't? Obviously, the proper way to terminate a wire rope was not in this person's skill set. Good intentions mean little if someone gets injured due to a rigging failure.
- Know your load.
- Know your cable strength.
- Know how to apply a safety (design) factor for live loads vs static loads.
- Know the efficiency (derating) of the termination method (Crosby's are different than Nicopress).
- Know how to install a cable thimble.
- Know how to terminate it for maximum safe load carrying capacity.
If you use cable clips ("Crosby's"):
- Know how to install them ("Never saddle a dead horse" means don't install the forged cable grip over the unloaded tail of the cable).
- Know how many you need.
- Know the spacing required.
- Know the torque of the bolts/nuts and use a torque wrench to achieve it.
If you use crimp-on sleeves ("Nicopress"):
- Know how to install them.
- Know how many you need.
- Know the spacing required.
- Know which axis of the compression oval is to be crushed (crimped).
- Know how to check and adjust the crimping tool so the die properly siezes the compression oval.
- Use a Go / No-Go gauge to check your finished crimps.
