Kranigo: Crane Lift Planner

Kranigo is a range chart planning aid for crane operators, lift planners and appointed persons. Draw the crane, the load and the site to scale, then check radius, boom angle, heights and clearances before the lift. RANGE CHARTS • Live range chart: radius, boom angle and % of chart update as you drag. • Capacity zones from the crane's load chart, with a clear status at the hook. Load charts are read conservatively and never interpolated unless the chart allows it. • Up to ten rulers that snap to the hook, boom tip, object corners and the ground. SITE OBJECTS AND HAZARDS • Buildings, powerlines, trees, loads, scaffolds, excavations and more. • Spotter and no-go zones, approach distances and warnings right on the chart. MY CRANES • Start with the demo cranes (fictional examples), then add your own. • All-terrain, city, crawler, tower and more: set geometry, hook blocks, load charts and paint. CALCULATORS • % of chart, max load, min WLL, point load, pad size, slings and unit conversion. PROJECTS AND PDF • Folders for every site. Search by name, job number or client. • Export a one-page PDF with the range chart, title block, capacity summary and disclaimer. BUILT FOR SITE • Works offline. No account and no ads. • Your projects stay on your device. • Metric and imperial units. • High-contrast Sunlight theme for outdoors, plus light and dark. • iPhone and iPad. FREE AND PRO The free version includes one of your own cranes, three projects, the calculators and PDF export (with a small "Made with Kranigo" mark). Kranigo Pro removes the limits and the mark.

PLANNING AID ONLY Kranigo is a planning aid for competent crane professionals. Always verify against the manufacturer's load chart, the crane's RCI/LMI and site conditions. A competent person must approve every lift. Terms of Use (EULA): https://kranigo.topsol.org/terms Privacy Policy: https://kranigo.topsol.org/privacy
