Sling Load Calculator Easy vs Rigwise

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!

Rigwise is the rigging calculator built for the field — fast, correct, fully offline, and a one-time purchase. No subscription. No account. No internet required. Your data never leaves your phone. Built for crane riggers, signal persons, ironworkers, and anyone who plans a lift. THE CALCULATORS (always free) • Sling Tension — see how the load in each leg climbs as the sling angle drops. Enter the angle, or just the sling length and height. Clear red warning below 30°. • Working Load Limit — vertical, choker, and basket hitches, with the angle and D/d reduction factors applied. • Center of Gravity — find how much each pick point actually carries when the load is off-center. • Crane Capacity % — check your load against the chart capacity, with a warning when you're over. Every result shows a plain-language safety state, glove-readable, in light or dark. RIGWISE PRO — the studio (one-time purchase, yours forever) • Gear inventory — log your slings, shackles, chains, and hooks with their tagged WLL. • Inspection tracking — Rigwise flags gear that's overdue for inspection before you grab it. • Lift Plans — save a named lift; Rigwise re-computes the numbers from your inputs so a saved plan is never a stale, hand-typed figure. • Field-ready export — share a clean lift-plan summary with your crew. WHY RIGWISE • Works 100% offline — job sites don't have signal. • One-time purchase — the tools you paid for keep working, forever. • Private by design — no account, no tracking, nothing collected. • Correct — the math is deterministic and exhaustively tested against standard rigging practice. SAFETY Rigwise is a calculation aid. Always verify every result against the manufacturer's tag, the load chart, and a qualified person. It is not a substitute for an engineered lift plan or professional judgment. Rigging is inherently hazardous; you are solely responsible for the safety of any lift.
