Sling Angle & Tension Calc

About to pick a load with a multi-leg sling and need to verify the tension per leg is within safe limits? Exceeding the sling angle threshold can cause catastrophic failure. This app computes angle, tension per leg, and design factor for 2, 3, and 4-leg configurations instantly. Enter load weight, sling length, and attachment spread. Get sling angle from vertical, tension per leg, design factor, and pass/fail check against WLL. WHAT IT CALCULATES: - Sling angle from vertical - Tension per leg for 2, 3, and 4-leg hitches - Design factor vs rated capacity - Pass/fail safety check - Horizontal and vertical force components HITCH TYPES: - Vertical hitch - Choker hitch - Basket hitch - Multi-leg bridle (2, 3, 4 legs) KEY FEATURES: - OSHA and ASME B30 angle guidelines - Color-coded safety status - Works completely offline - No account or login required Built for riggers, crane operators, ironworkers, and safety officers.
