Sling Load Calculator Easy vs RigMaster

Sling Load Calculator Easy is your essential tool for quick and precise rigging calculations. Designed for riggers, crane operators, and safety supervisors, this app simplifies complex lifting physics into a user-friendly interface. Whether you are on-site or planning a lift, you can determine the tension on each sling leg in seconds. The app offers two flexible modes of calculation: • By Dimensions: Enter the load width (A) and sling length (L) to get instant results. • By Angle: Enter the horizontal sling angle (\beta) directly to see how it affects your load. Key Features: • Multi-Leg Support: Adjust the number of sling legs to match your specific rigging setup. • Dual Input Modes: Toggle between measurements and angles with a single click. • Real-Time Calculations: Get instant tension results as you change your parameters. • Simple & Clean Interface: No clutter—just the tools you need for accurate rigging math. Ensure safety and prevent sling overload with the most intuitive calculator on the App Store. Download Sling Load Calculator Easy today!

RigMaster is the rigging calculator built for working riggers, crane operators, and signal persons. LIFT PLAN PDF (PRO) • Turn any calculation into a one-page lift plan: diagram, inputs, results • Room for notes and three signature lines — prepared by, signature, date • Share it straight to the supervisor from the toolbar IPAD & UNITS • Universal app — two-column layout on iPad, any orientation • Metric or imperial — kg and metres or lb and feet, switch any time • Live sling diagram with the angle and tension on every leg FREE CALCULATORS • Sling Tension — 2-leg picks by angle, or by sling length & height (the way you actually measure) • Hitch Capacity — vertical, choker (reduced by the choke angle) 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 • Horizontal pull per leg — the compression a spreader beam has to carry • 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. COMMON QUESTIONS Does it work offline? Yes. Every calculation runs on the phone. No signal needed on site. Do I need an account? No. There is no login and no sign-up. What is free? Sling Tension, Hitch Capacity and the Angle Reference table are free. Pro adds 3 and 4-leg bridles, unequal legs with CoG offset, the load weight estimator and the lift plan PDF, and removes the ads. Metric or imperial? Both, switchable at any time — kg and metres, or lb and feet. Can I hand the result to the supervisor? Yes. Pro turns any calculation into a one-page lift plan PDF: diagram, inputs, results, notes and three signature lines. Does it replace the sling tag or the load chart? No. It is an estimation aid for qualified riggers. The sling tag, the load chart and your site's rigging plan always come first. Does it work on iPad? Yes. Universal app, two-column layout on iPad, any orientation. Terms of Use: https://ghapps1.wordpress.com/terms-condition/ Privacy Policy: https://ghapps1.wordpress.com/privacy-policy/
