RIGGING MODE
Safety Guidelines
Critical Rule
Never lift with sling angles below 30° from horizontal. Tension increases exponentially as angles decrease.
30°
Minimum Safe Angle
60°
Recommended Standard
2.0x
Tension at 30°
1.15x
Tension at 60°
How It Works
As the sling angle decreases, the horizontal force component increases, dramatically raising the tension in each sling leg. This simulator shows real-time tension changes.

CRITICAL ANGLE!
Tension exceeds 90% of theoretical. Reduce load or increase angle.
DANGER ZONE!
Angle below recommended limits. Tension doubled!

Formula
Tension = (Load / 2) × Factor
Factor = 1 / sin(angle)
