BYO Lift Planning — Bring Your Own Load Chart

Your crane isn't in their database?
Ours doesn't need one.

Snap a photo of your crane's rated load chart. AI digitizes it in about a minute — you verify every number — then plan lifts with automatic capacity lookup, drawings, and PDF lift plans. Any brand. Any model. Any year.

The Database Problem

Lift planning apps only know the cranes they ship with.

Built-in databases never cover your whole fleet — older models, regional variants, that one crane with the odd counterweight setup. ONCRANE flips the model: your chart is the database.

✓
No waiting for a database updateIf you have the manufacturer's chart in hand, you can be planning lifts with it today.
✓
Every configuration, as its own pageCounterweight options, outrigger settings, jib charts — stack multiple chart pages on one crane and switch with a tap.
✓
Your data follows youCharts sync to the cloud. Change phones, switch to a PC — your fleet is still there.

How It Works

Snap. Verify. Plan.

Digitizing a rated capacity chart by hand takes half a day. ONCRANE gets you there in minutes — with you checking every value before it's saved.

Snap your load chartTake a photo of the manufacturer's rated load chart — or pick an image. AI reads the full table: radii, boom lengths, extension modes, hook config.
Verify every numberAI is the draft, you are the check. Suspicious cells are flagged automatically (loads must decrease as radius grows), and you compare against the original before saving. Nothing is guessed.
Plan the liftSet the working radius — rated capacity appears automatically, rounded to the safe side. Drawings, rigging WLL, outrigger loads, ground pressure, PDF lift plan.
Features

Everything between the chart and the lift plan.

One app from crane data to submitted paperwork — on PC, phone, or tablet. Metric and imperial.

AI

AI load chart reader

Photo → digital chart, including per-column extension modes and hook data. Unreadable cells stay blank — never guessed.

PLAN

Lift plans with auto capacity

Radius in, rated capacity out — always rounded to the safe side. Elevation & plan drawings with obstacles and power-line clearance checks.

VS

Performance tables & compare

Browse any registered chart as a clean table, look up capacity at any radius, and compare two cranes (or two configs) side by side.

PDF

Rigging, loads & PDF output

Sling WLL by angle and legs, estimated outrigger reaction and ground bearing pressure, and a drawing-included PDF lift plan.

Safety First

Built to assist judgment — never to replace it.

ONCRANE is developed by a company that owns and operates cranes. We built the safeguards we'd demand on our own job sites.

You verify before anything is savedAI output is a draft. The app requires a side-by-side review screen, flags physically inconsistent cells, and recommends a retake when the photo is poor.
Safe-side capacity lookupWhen the working radius falls between chart rows, ONCRANE always uses the longer radius — the smaller, safer capacity.
Safety notice: All values shown in ONCRANE are reference values to support planning. Before any actual lift, always verify against the manufacturer's official rated capacity chart and the crane's LMI/rated capacity limiter. Final decisions rest with qualified, competent persons on site. ONCRANE is not affiliated with or endorsed by any crane manufacturer.
