Synthetic Sling Inspection Care

Inspection, Care, and Use Tips for Synthetic Web Slings

Removal From Service if any of the Following:

  • If sling rated capacity tag is missing or not readable
  • Acid or alkalis burns
  • Melting, charring, or weld spatter of any part of the sling
  • Holes, tears, cuts, snags or embedded particles
  • Broken or worn stitching in load bearing splices
  • Excessive abrasive wear
  • Knots in any part of the sling
  • Distortion, excessive abrasive wear
  • Any conditions which cause doubt as to the strength of the sling

Operating Practices

  • Determine weight of the load. The weight of the load shall be within the rated capacity of the sling.
  • Select sling having suitable characteristics for the type of load, hitch and environment.
  • Slings shall not be loaded in excess of the rated capacity. Consideration shall be given to the sling to load angle which affects rated capacity. (See load chart.)
  • Slings with fittings which are used as a choker hitch shall be of sufficient length to assure that the choking action is on the webbing, and never on a fitting.
  • Slings used in a basket hitch shall have the load balanced to prevent slippage.
  • The opening in fittings shall be the proper shape and size to ensure that the fitting will seat properly in the hook or other attachments.
  • Slings shall always be protected from being cut by sharp corners, sharp edges, protrusions or abrasive surfaces.
  • Slings shall not be dragged on the floor or over an abrasive surface.
  • Slings shall not be twisted or tied into knots, or joined by knotting.
  • Slings shall not be pulled from under loads if the load is resting on the sling.
  • Do not drop slings equipped with metal fittings.
  • Slings that appear to be damaged shall not be used unless inspected and accepted.
  • The sling shall be hitched in a manner providing control of the load.
  • Personnel, including portions of the human body, shall be kept from between the sling and the load, and from between the sling and the crane hook or hoist hook.
  • Personnel shall stand clear of the suspended load.
  • Personnel shall not ride the sling.
  • Shock loading shall be avoided.
  • Twisting and kinking the legs (branches) shall be avoided.
  • Load applied to the hook shall be centered in the base (bowl) of hook to prevent point loading on the hook.
  • During lifting, with or without the load, personnel shall be alert for possible snagging.
  • The slings' legs (branches) shall contain or support the load from the sides above the center of gravity when using basket hitch.
  • Slings shall be long enough so that the rated capacity of the sling is adequate when the angle of the legs (branches) is taken into consideration. (see load chart).
