Safe Operating Practices
Whenever any sling is used, the following practices shall be observed:

  • Slings that are damaged or defective shall not be used
  • Eyes in wire rope slings shall not be formed by using knots or wire rope
  • Slings shall not be shortened with knots, bolts or other makeshift devices
  • Sling legs shall not be kinked
  • Slings shall not be loaded in excess of their rated capacities
  • Slings used in a basket hitch shall have the loads balanced to prevent slippage
  • Slings shall be securely attached to their loads
  • Slings shall be padded or protected from the sharp edges of their loads
  • Suspended loads shall be kept clear of all obstructions
  • All employees shall be kept clear of loads about to be lifted and of suspended loads

Sling Failure in Straight Tensile Pull

  • Wire rope slings with hand tucked spice eyes normally fail at the last strand tuck — away from crotch of the eye. Wire rope slings with mechanically spliced eyes normally fail at the nose of the pressed sleeve
  • Mechanical spliced sling efficiency vary from 95% of wire rope strength for 1/4″ through 1″ to 92.5% for 1 1/8″ through 2 1/2″. Fiber core is not recommended for mechanically spliced slings
  • Hand spliced sling efficiency vary from 90% for 1/4″ to 80% for 7/8″ through 2 1/2″.
