About
RigMaster is the rigging calculator built for working riggers, crane operators, and signal persons. FREE CALCULATORS • Sling Tension — 2-leg picks by angle, or by sling length & height (the way you actually measure) • Hitch Capacity — vertical, choker, and basket capacity from YOUR sling's tag rating • Angle Reference — the tension multiplier table, always in your pocket PRO CALCULATORS • 3 & 4-leg bridles with rigid/flexible load sharing • Unequal Legs / CoG Offset — tension per leg when the center of gravity isn't centered • Load Weight Estimator — steel, concrete, aluminum and more, by shape and dimensions • Ad-free Built on first-principles trigonometry with warnings at 45° and hard alerts below 30°, following standard rigging practice (ASME B30.9 guidance). RigMaster is an estimation aid for qualified riggers. Always follow the sling tag, the load chart, and your site's rigging plan.
