Green Log Weight Calculator

The premier green log weight calculator, 3D volume estimator, and ANSI Z133 crane safety tool engineered exclusively for iOS and iPadOS. Built specifically for professional arborists, crane operators, tree removal crews, and forestry technicians. Whether you are rigging heavy timber in tight urban drop zones or estimating crane capacity for daily tree operations, Green Log Weight Chart 3D equips your crew with precise mathematical formulas, real-time safety gauges, and automatic private iCloud backup. === KEY FEATURES === AUTOMATIC PRIVATE iCLOUD (CLOUDKIT) SYNC Seamlessly sync your daily lift plan logs across your iPhone and iPad. Your cut records are automatically backed up to your personal private iCloud database—ensuring your data persists across app reinstalls and device updates with zero account setup needed. COMPREHENSIVE 66 WOOD SPECIES DATABASE Access green weight densities (lbs/ft³) for 66 North American and international tree species across Hardwood and Softwood categories—including Live Oak, White Oak, Sugar Maple, Green Ash, Douglas Fir, Incense Cedar, and Black Walnut. 4 MATHEMATICAL LOG VOLUME FORMULAS Select the exact volumetric math formula required for your site conditions: • Uniform Cylinder: Fast estimation for straight trunk sections. • Frustum of a Cone: Accurately calculates natural trunk taper from butt to top diameter. • Smalian's Formula: Industry-standard formula using butt and top cross-sectional areas. • Huber's Formula: Precise volumetric calculation based on mid-log diameter. REAL-TIME 3D TIMBER GEOMETRY STUDIO Inspect timber cuts in interactive 3D. Dynamically adjust length, butt diameter, and top diameter while observing real-time weight distributions, center of gravity shift, and volumetric geometry. CRANE SAFE WORKING LOAD (SWL) GAUGE Input your crane model, boom radius capacity, rigging hardware weight, and desired safety factor. The app automatically calculates total suspended load (wood + rigging) and displays a color-coded safety percentage gauge: • Green (Safe): Under 80% safe working load. • Amber (Warning): 80% to 95% capacity – proceed with caution. • Red (Critical): Exceeds safe limit – instant overload alert. ANSI Z133 SECTION 5.7 COMPLIANCE & CHECKLIST Satisfy OSHA and ANSI Z133-2017 safety regulations requiring green log weight charts on site. Built-in interactive pre-lift safety checklist includes: • Drop Zone Radius Estimator (Automated 1.5x Tree Height safety boundary) • Outriggers and ground pad stability verification • Rigging line and radio communication pre-flight checks BRANDED PDF LIFT PLAN REPORTS & EXPORT Generate professional, job-ready PDF Lift Plan Reports for site supervisors, clients, and crane rental agencies. Share via AirDrop, Email, Files, or Print directly from the field. LOG STACK & TRUCKLOAD ESTIMATOR Calculate total weight and volume for bulk log piles, grapple truck loads, and log trailers in Cords, Tons, or Board Feet. OFFLINE-FIRST ARCHITECTURE Cellular service down on remote job sites? No problem. The entire species database, 3D visualizer, math engine, and PDF generator run 100% offline directly on your iPhone or iPad. DUAL IMPERIAL & METRIC SUPPORT Seamlessly toggle between Imperial (lbs, feet, inches, board feet) and Metric (kg, meters, cm, cubic meters).
