Rigging Lift Plan PDF: Document the Calculation

When a written record helps

Supervisors, lift planners and clients usually want to see how the sling loads were worked out, not just hear that they were. A single page with the numbers, the angle and a signature is easy to check, file with the job paperwork or attach to a permit.

What is on the page

The title Lift Plan, the calculator name and today's date.
A sling diagram for Sling Tension, Unequal Legs and the Basket hitch. Load Weight and the Vertical and Choker hitches have no diagram.
A table of inputs and results with the main number printed large. It turns coloured with a warning icon when the angle is in the caution or danger band.
Three ruled Notes lines, and Prepared by, Signature and Date lines.
The estimation-aid disclaimer.

The page is US Letter when the device uses US measurements and A4 otherwise. The file is named after the calculator, for example Lift Plan — Sling Tension.pdf.

Steps in RigMaster

Finish the calculation on Sling Tension, Hitch Capacity, Unequal Legs or Load Weight.
Tap Lift Plan in the toolbar. It is greyed out until there is a result, and without Pro it opens the upgrade screen.
Pick where to send the PDF from the share sheet: mail, messages, Files or a printer.
Print or mark it up, fill the Notes, and sign on the Prepared by and Signature lines.

Free alternative: share from History

Without Pro, tap Save on the calculator, open History, then swipe right on the entry or long-press it and choose Share. You send the calculator name, inputs and result as plain text. It has no diagram or signature lines, but it is a written record.

What a full crane lift plan also needs

RigMaster's sheet covers the rigging only. A lift plan for a crane pick normally also records things the app knows nothing about, and those have to come from the crane's documentation and the site:

Crane make, model and configuration, counterweight, boom length and radius.
Load chart capacity at that radius and the percentage of capacity used.
Ground conditions, outrigger or mat loading, and nearby hazards such as power lines.
Exclusion zones, communication method, the people involved and their roles.

Questions and answers

Is there a lift plan app for iPhone?

RigMaster makes a one-page PDF of the rigging calculation on iPhone and iPad. It does not plan the crane side of a lift, such as radius, boom or load chart.

Can I get the PDF without Pro?

No, the Lift Plan PDF is a Pro feature. Free users can save a result and share it as plain text from History.

Does the PDF include a diagram?

For Sling Tension, Unequal Legs and Basket hitch sheets, yes. Load Weight and Vertical or Choker hitch sheets show the table only.

Is the page Letter or A4?

Letter when the device uses US measurements, A4 otherwise.
