Sling Angle Tension Multipliers & Capacity Retention Reference (ASME B30.9)
As the horizontal sling angle between the load and the sling leg decreases below 90 deg, tension inside each sling leg increases sharply. Multiply your load weight (or divide single-leg vertical capacity) by the ASME B30.9 angle factor below, and never rig below a 30 deg horizontal sling angle without engineering approval:
| Horizontal Sling Angle | Included Angle (2 Legs) | Tension Multiplier per Leg | Effective Capacity Retained | Rigging Recommendation |
|---|---|---|---|---|
| 90 deg (Vertical) | 0 deg | 1.000 x Load | 100% of Vertical WLL | Full rated vertical capacity |
| 60 deg Angle | 60 deg | 1.155 x Load | 86.6% per Leg | Preferred multi-leg bridle & basket angle |
| 45 deg Angle | 90 deg | 1.414 x Load | 70.7% per Leg | Standard minimum working angle for general picks |
| 30 deg Angle | 120 deg | 2.000 x Load | 50.0% per Leg | Caution: leg tension equals full load weight (50% reduction) |
