Crane Lift Planner

Built for crane operators, riggers, and lift directors who need quick capacity verification on the iron - not a dashboard you log into.

WHAT IT DOES
Looks up rated capacity at any operating radius for 5 common crane configurations using built-in load chart data with linear interpolation. Compares total rigged load against rated capacity and flags critical-lift thresholds before the hook leaves the ground.

CRANES INCLUDED
- 30-ton Rough Terrain
- 50-ton Rough Terrain
- 80-ton Rough Terrain
- 130-ton Rough Terrain
- 200-ton Crawler

INPUTS
- Crane model (picker)
- Load weight (lb)
- Rigging weight (lb, default 500)
- Operating radius (ft)

RETURNS
- Rated capacity at the entered radius (tons)
- Total rigged load (lb and tons)
- Load as a percentage of rated capacity
- Critical-lift status: under 75% (green), 75-90% (yellow), 90-100% (orange), over capacity (red)
- Full load chart for the selected crane

WHY THIS APP, NOT THE FREE ONES
- Math is shown - every result lists the chart entry and the load ratio. No black box.
- Color-coded thresholds - see at a glance whether you are approaching critical-lift territory.
- Works offline - yard moves, refinery turnarounds, and remote sites. Always available.
- No login. No ads. No telemetry. No subscription.

PRICING
$4.99. Pay once, own it. Will not disappear when the company kills the SaaS budget. Lifetime access on iPhone, iPad, and Mac via Family Sharing.

NOT A SUBSTITUTE FOR
The crane manufacturer's published load charts for your specific machine. The lift director's sign-off. A site-specific ground bearing capacity assessment. This app is a quick-reference tool, not a replacement for the official load chart taped to the cab.
