Crane Outrigger Pad Calc vs Rigger Pro

Built for crane operators, lift planners, and ground crews who need outrigger pad sizing on the iron - not a dashboard you log into. WHAT IT DOES Computes ground pressure under a single outrigger pad and checks pass/fail against the allowable soil bearing capacity and the pad material's allowable stress. Compares up to 10 saved configurations side-by-side for a multi-pick lift. Reference tables for soil types and common pad sizes are built in for quick cross-check. INPUTS - Load per outrigger (lb) - Pad shape: Square, Round, or Rectangular - Pad dimension(s) (in) - Pad material: Timber, Oak, Steel Plate, HDPE, Composite - Allowable soil bearing (psf) RETURNS - Pad area (sq in and sq ft) - Ground pressure (psf and psi) - Pass/fail vs. allowable soil bearing - Pass/fail vs. pad material allowable stress - Minimum required pad side (in) when over the limit - Multi-load comparison rows for up to 10 configurations - Soil bearing capacity reference table (6 soil types) - Common pad size reference (2x2 to 6x6 ft, max load at varying soil bearing) WHY THIS APP, NOT THE FREE ONES - Math is shown - every result lists the area, pressure, and the limit it is compared against. - Multi-load mode - save the four-corner configuration for an asymmetric pick and review at once. - Works offline - yard moves, off-road sites, no cell service. Always available. - No login. No ads. No telemetry. No subscription. PRICING $4.99. Pay once, own it. Lifetime access on iPhone, iPad, and Mac via Family Sharing. NOT A SUBSTITUTE FOR A site-specific ground assessment by a qualified person. A geotechnical report for soft sites, fill, or organic layers. The crane manufacturer's outrigger-pad guidance for your specific machine. This app is a quick-reference tool, not a replacement for engineered ground bearing analysis.
