What it is.

Sling tension by angle, worked against the tag, and the signal person's qualification item by item. Use when a rigger sizes slings or a signal person is checked. Not for digging before 811 or lifting off the chart. For the pick, the chart and the crane → THE CRANE OPERATOR.

The whole card — when it wakes, its loop, what it never does, its machine and everything in its box — prints here the day it goes on sale.

Take it.

Nº 1419 —Liquid error (snippets/job-room line 44): comparison of String with 0 failed

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not medical, legal, tax or financial advice, never the person’s boss, and not a licence to practise. The terms →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

One email when it is on sale, from the studio; nothing else, ever.
