1. Daily check: visible faults in links or hooks.
  2. At least twice a year:
    • Clean slings prior to inspection.
    • Hang the chain sling up or stretch the sling out on a level floor. Remove all twists. Measure the length. Discard if sling has been stretched.
    • Make a link-by-link inspection.
  3. At least once a year:
    We recommend to have the chain sling proof tested to twice the WLL and re-certified by Unirope.
  1. It is important to inspect chain slings and to keep a record of individual chain inspections. The Unirope Sling Inspection Service takes care of this.
  2. Remove from service if you detect:
    • Missing or illegible capacity tags;
    • cracks or breaks, wear, nicks, gouges;
    • stretched chain links or components;
    • bent, twisted or deformed chain links or components;
    • evidence of heat damage, weld splatter;
    • pitting or corrosion;
    • lack of ability to hinge freely;
    • 13% or more wear on any point on a link (for exact values refer to ASME B30.9).


Remove from service if you detect:

13% Wear Nicks, Cracks Stretch
Twisted Links, Deformed Hardware

About the importance of sling inspections

A seemingly intact chain sling may look ‘o.k.’ at a glance but a closer look reveals a dangerous condition of badly worn links. This is why it is so important that lifting slings are regularly inspected by the user.
