RigMaster: Rigging Calculator

RigMaster is the professional rigging sling tension calculator, 2D vector statics solver, and crane lift planning system built for riggers, crane operators, lift directors, safety inspectors, and structural engineers. Whether you are rigging a 50-tonne transformer on a construction site, lifting an offshore skid module, or conducting routine shop picks, RigMaster eliminates guesswork with mathematically rigorous, field-verified calculations that strictly comply with ASME B30.9, OSHA 1926.251, EN 1492, AS 3775, and ASME B30.26 standards. ================================================== KEY ENGINEERING FEATURES ================================================== 1. ADVANCED SLING TENSION CALCULATOR * Multi-Leg Bridle Configurations: Instant tension analysis for 2-leg, 3-leg, and 4-leg bridles. * Specialized Hitches: Precise deration and capacity multipliers for Choker Hitches, Basket Hitches, and Straight Vertical pulls. * Non-Symmetric & Offset CoG Analysis: Enter 3D Center of Gravity offsets (X, Y, Z) and hook heights to accurately calculate unequal leg tensions and sling angle distributions. * Instant Safety Status: Immediate color-coded status (Optimal >45°, Warning 30°-45°, Critical <30°) prevents dangerous shock loading and rigging failure. 2. COMPREHENSIVE EQUIPMENT LOFT & ASSET MANAGEMENT * Pre-configured rigging hardware database: - 6x19 & 6x36 EIPS / EEIPS Wire Rope Slings (1/2" to 2") - Grade 80 & Grade 100 Alloy Chain Slings (Pewag, Gunnebo, Campbell) - Synthetic Web Slings (1-ply & 2-ply Type 3 & 4 Nylon / Polyester) - High-capacity Polyester Endless Roundslings (color-coded WLL) - Crosby G-209 & G-2130 Anchor Shackles * Track serial numbers, inspection dates, condition status (In Service, Quarantined, Overdue), and custom WLL ratings. 3. PRE-USE INSPECTION ENGINE * 8-point inspection checklist based on ASME B30.9 and OSHA criteria (broken wires, kinking, heat damage, arc strikes, tag legibility, corrosion, end-fitting integrity). * Instant pass/fail audit trails with digital timestamping and tamper-evident logs. 4. PROFESSIONAL LIFT PLANNING & PDF DOSSIERS * Generate comprehensive, multi-page Lift Planning Dossiers ready for client review, crane permit approval, and insurance compliance. * Dual Digital Signatures: Secure sign-off workflows for Lift Director and Lead Rigger. * Cryptographic QR Verification: Embedded QR code with SHA-256 pre-rendered manifest hash allows field safety officers to verify plan integrity instantly with any camera. 5. REGIONAL STANDARDS & UNIT SWITCHER * Seamless toggle between Metric (kg, tonnes, kN, metres, mm) and Imperial (lbs, US short tons, feet, inches). * Built-in capacity reference tables for ASME B30.9 (US), EN 1492 / EN 818 (Europe), and AS 3775 (Australia/NZ). ================================================== DESIGNED FOR HARSH INDUSTRIAL ENVIRONMENTS ================================================== * 100% Offline Architecture: Zero cloud dependencies for calculations. Operates flawlessly in deep basements, offshore oil platforms, remote wind farms, and steel mills without internet. * High-Contrast Midnight Oasis UI: Engineered with safety-orange/amber accents and ultra-dark OLED contrast for crystal-clear readability in direct sunlight or nighttime operations. * Zero Ads, Zero Bloat: Streamlined, enterprise-grade engineering calculator with lightning-fast response times.
