Kranigo: Crane Lift Planner

Kranigo draws your crane and the job site in side view — a live crane range chart. Drag the boom and the radius, tip height, clearances and % of chart update as you move. A lift planning aid made for crane operators, dogmen, riggers and lift planners, by TOPSOL.

FREE TO START — no card, no sign-up. One crane, three projects and PDF export, free forever. Kranigo Pro (unlimited cranes and projects, clean PDFs) is a simple subscription from $1.99/month with a 7-day free trial.

PLAN EVERY LIFT ON A LIVE RANGE CHART
• Boom, jib and hook move with your finger; radius, angle and heights update live.
• Capacity zones at every radius, colour-coded from the crane's load chart, with a clear status at the hook.
• Works fully offline — in the yard, on site, in the basement.

SPOT SITE HAZARDS EARLY
• Add buildings, trees and powerlines; approach distances and no-go zones appear right on the range chart.
• Up to ten rulers that snap to the hook, boom tip, object corners and the ground — measure any clearance in seconds.

BUILD YOUR OWN FLEET
• All-terrain, city, crawler, tower, pick-and-carry and more: set geometry, load charts and paint, and reuse your cranes on every lifting job.

SITE MATHS WITHOUT THE PAPERWORK
• Crane and rigging calculators: % of chart, max load, minimum sling WLL, point load, outrigger pad size and unit conversion.
• Metric and imperial, everywhere.

ORGANISE JOBS, SHARE A CLEAN PDF
• Folders for every site and client. Export the range chart as a professional PDF with title block and capacity summary — quote on site, not back at the office.

BUILT FOR SITE
• High-contrast Sunlight theme readable in bright sun, plus light and dark.

Kranigo is a lift planning aid for competent crane professionals. Capacity readings are conservative by design: between chart rows Kranigo takes the next-safer value — never interpolated, never guessed — and display rounding always rounds the safe way. It does not replace the crane manufacturer's load chart, site procedures or a competent person, and every exported range chart PDF says so. Sample cranes and charts in the app are fictional demonstration data.
