How this works: answer each question about the ground, access, overhead conditions, weather and set-up space. Any "critical" answer weighs heaviest and pushes the result to do-not-proceed; softer flags trigger caution. Use it to structure your site inspection — it does not replace a competent person's assessment.
General guidance only. This tool gives indicative results from the numbers you enter. It is not engineering advice, a compliance assessment or a substitute for a competent person, AS 2550 requirements or your crane manufacturer's documentation. Verify anything safety-critical with a qualified professional before acting on it.
