Enter your crane's load chart once, straight from the book in the cab. Every lift after that: boom length, radius, load, hook block and rigging in, rated capacity, percent of capacity and an OK / Critical Lift / Do not lift call out, fully offline. Save the lift and share a one-page lift plan as an image or PDF.

LiftChart Pro is a $24.99/year auto-renewing subscription that unlocks unlimited cranes and load charts, the lift plan PDF with range diagram and outrigger loads, history search and your company name on every plan. All calculations stay free. Manage or cancel in your Apple ID settings.
Rated capacities and percentages are reference aids computed from the values you enter. Always verify against the manufacturer's load chart and follow OSHA, ASME and site rules.
