Operating Practices for Alloy Chain Slings

Warning

  • Can Fail if Damaged, Misused or Overloaded.
  • Inspect Before Use.
  • Use Only if Trained.
  • Observe Rated Load.
  • Pad Edges of Load to Avoid Damage to Sling.
  • Death or Injury can Occur from Improper Use or Care.

Instructions for Care, Use, Inspection and Repair of Alloy Chain Slings

Care:

  • Store on a rack away from possible mechanical damage, corrosion, dust, grit, extreme temperatures, sun and any ultraviolet light source.
  • Do not anneal (temper) alloy chain, connecting links or hooks. Hot galvanizing requires chain manufacturer’s advice.

Use:

  • Check weight of load.
  • Check tag to confirm that sling is rated adequately for the load (see load angle chart).
  • Sling shall not be twisted, tied into knots or joined by knotting.
  • Be sure the load cannot cut the sling during the lift by padding corners, edges, protrusions, or abrasive surfaces; use materials of sufficient strength and thickness.
  • Center load on base (bowl) of hook unless sling hook is designed for point loading.
  • Balance the load.
  • Maintain load control.
  • Avoid jerking the load.
  • Be alert for snagging of load.
  • Avoid dragging sling over rough surfaces and from under the load.
  • Choker hitch must choke on sling body, never on end fitting.
  • Always stand clear of load.
  • Persons are not to ride on sling or load.
  • If sling is to be used in a chemical environment or in temperatures below -40° f or above 400°F. Contact manufacturer for specific recommendations.
  • When shortening chain, use only the manufacturer’s recommended alloy components.
Inspection:
  • Before each use, check for nicks, gouges or excessive wear.
  • Inspect for bent, twisted, deformed chain or components.
  • Inspect for heat damage, weld spatter, pitting or corrosion, increase in hook throat opening, missing latch (if so equipped).
  • If this wear or damage is present, if rated load tag is missing or illegible, remove from service and repair or replace sling.
  • Periodic inspections are required at least annually for normal service, quarterly or more frequently if in severe service or nearly constant use.
  • Periodic inspections are performed only by chain manufacturer or other designated person who records the observed condition and determines when further use would be hazardous.

Repair:

  • Any hazardous condition disclosed by an inspection shall require repair by chain manufacturer or other qualified person.

Load Angle for Slings

  • Angle factor must be applied to calculate the reduced sling capacity when lifting force is not at 90º to the plane of the load.
  • Multiply angle factor x sling's vertical rated load to calculate the reduced capacity at that angle.
  • Because of the greatly reduced lifting capacity, use extra care when the sling to load angle, also known as the horizontal angle, is less than 45° and do not make lifts of less than 30°load angle.
  • Example: a sling with adequate capacity could be broken because of increased tension resulting from angles of less than 30°.

D-d Ratio for Slings

  • Rated capacity of the sling shall be decreased when D:d Ration will be smaller than that cited in the latest revision of ASME B30.9 Ch2.
  • Consult the sling manufacturer for specific data or refer to the WRTB Wire Rope Sling User's Manual.
  • General Note: When the (D) is 25 times the component rope diameter (d), the D:d Ration is expressed as 25:1.
