## What is Crane Outrigger Pad Calc?

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.
