Alloy Chain Sling Information



Before inspecting and using your sling, clean the chain so that defects can be easily seen. When chain slings are in storage, they should be oiled to prevent corrosion and hung so that chains do not knot or twist together.

  • Slings should be hitched so that they control the load.
  • All sharp edges in contact with the sling should have padded material of sufficient strength to protect the sling.
  • Only shorten or adjust the sling by methods approved by the manufacturer.
  • Alert personnel to possible snagging of sling.
  • The sling should not be constricted or pinched by the load, hook, or any fitting.
  • Make sure the load applied to the hook is centered in the base of the hook.
  • Do not rest loads on the sling.
  • Do not pull a sling from under a load when the load is resting on the sling.
  • Do not allow shock loading of the sling.
  • Always avoid twisting and kinking the chain sling

Environmental/Chemical Factors

  • Avoid using acid solutions which can alter its molecular structure and strength.
  • Excessive low or high temperatures can reduce the performance of chain slings.
  • Normal operating temperatures are -40 degrees Fahrenheit to 400 degrees Fahrenheit.


Reduction Factors


Alloy Chain Sling Reduction Factors


All of our alloy chain slings are designed for long life under punishing conditions, but they will eventually wear out after extended use. The key is knowing when to replace them, and that is why it’s very important to inspect your slings on a regular basis.


Inspection intervals

Initial Inspection -  whenever the sling is initially received, altered, modified, or repaired.

Frequent Inspection - before each shift or day in normal service.Written records are not required for frequent inspections.

Periodic Inspection - an inspection done by a qualified and designated person and other than the person who performs the frequent inspections. Periodic inspection intervals should not exceed one year. Documentation that the most recent periodic inspection was performed shall be maintained.

The frequency of inspection depends on three important factors:
  1. Sling usage - the more you use a sling, the more you need to inspect it
  2. Working environment - the harsher the conditions, the more often you need to inspect. Check with the manufacturer before using chain slings in a chemically active environment as it may affect the sling.
  3. Sling service life - based on your experience in using slings.

    Removal Criteria

    Following are some things to look for when inspecting a web sling for damage:

    • Excessive wear.
    • Defective welds.
    • Cracks or breaks.
    • Excessive wear, nicks or gouges.
    • Stretched chain links or fittings.
    • Bent, twisted or deformed chain links or fittings.
    • Evidence of heat damage. Chain with have a blueish hue.
    • Excessive pitting or corrosion.
    • Lack of ability of chain or fittings to hinge freely.
    • Evidence of weld splatter.
    • Missing or illegible sling identification.
