How to Use the Sling Tension Calculator?

  • Enter load weight

  • Enter sling angle

  • Select number of slings

  • The calculator will display the tension in each sling

Rigging Safety Guidelines

  • Never exceed sling WLL

  • Maintain sling angles above 60° when possible

  • Inspect slings before use

  • Follow OSHA lifting safety practices

Why Sling Angle Matters in Rigging?

As the sling angle decreases, the tension in each sling increases significantly. Lower sling angles place greater stress on the rigging system and may exceed the sling working load limit (WLL). For safer lifting operations, rigging professionals try to keep sling angles above 60° whenever possible.

Sling Tension Formula

The sling tension can be calculated using the formula:
T = Load / (Number of slings × sin(angle))
