Chain Mesh Sling Information

Select:

 

Alloy chain mesh is excellent for handling hot or abrasive loads and loads which could cut into a web sling. These slings grip loads firmly helping to maintain balanced loads. Ensure that all slings are manufactured in accordance with OSHA and ANSI B-30.9 requirements.

Sling features

Chain Mesh Slings are made with Grade 100 alloy chain and alloy steel end fittings. The most common hardware used is the triangle and choker configuration. We can custom-make your chain mesh sling with alternate end fittings upon your request.

Following are some of the features of the chain mesh slings:

  • Excellent for hot and abrasive loads.
  • Proof-tested and certified.
  • Permanently stamped with capacity and serial number.
  • Chain mesh molds to load for greater balance.
  • End fittings accommodate most crane hooks.
  • High quality Grade 100 chain and components.

Care and usage

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. Additionally, avoid using acid solutions and heat which can alter its molecular structure and strength.

  • 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.
  • 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.
  • Always avoid twisting and kinking the mesh chain sling

Reduction Factors

  • Slings can be used in three common hitches; vertical, basket or choker.
  • Sling has the same load capacity in a vertical and choker hitch.
  • A Basket hitch increases the load capacity to twice the amount.

Chain Mesh Sling 
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.
