Slings age according to the same principles as rope, since they are produced from materials with very similar ageing behaviour. It is difficult to define their lifetime, since slings are often used differently. Check your sling every so often for signs of damage and use the following criteria to decide whether or not a sling or webbing needs to be replaced;

  • After a hard fall (mechanical damage as the result of frictional heat)
  • If the seam pattern is damaged (doubts in relation to strength)
  • In the event of irreversibly heavy soiling (for example, by grease, bitumen, oil, etc.)
  • After contact with acids, for instance from a car battery
  • After high thermal exposure (melting or signs of melting as a result of contact or frictional heat)

In the end, your own personal feeling of safety will decide when you no longer trust your sling.

The table below shows guide values for the service life of slings and webbing:
