Often riggers confuse a cut sling for a broken sling. View the pictures above to see the difference. The cut sling has come into contact with something sharp that has sliced the sling in half. You can tell by the clean edge. The broken sling has been pulled to destruction on our test bed. The ends are frayed and melted from heat friction.

Remove the sling from service if any of the following is visible:

  • If sling rated capacity or sling material indentification is missing or not legible.
  • Acid or alkalis burns.
  • Melting, charring or weld spatters on any part of the web sling.

  • Knots in any part of the web sling.
  • Excessive pitting, corrosion, cracked, distorted or broken fittings
  • Any other visible damage that causes doubt as to the strength of the sling.


Inspection Records
