ExploreAbout this exam
The Non-Slewing Mobile Crane licence - commonly called the CN licence - is an Australian high risk work licence for operating mobile cranes that cannot slew (rotate) while carrying a load. Typical machines include Franna-style pick-and-carry cranes and other articulated or rigid non-slewing mobiles used across construction, civil works, mining, manufacturing, and maintenance. The credential is issued by the national work health and safety regulator in each state or territory after you complete training with a registered training organisation and are assessed against the national competency standard. Assessment combines knowledge questions, a written or verbal component, and a practical demonstration on an actual crane, so both theory and hands-on control skills matter. The knowledge domains span legislation and duty of care, hazard identification and risk control, crane types and load charts, pre-operational inspection and setup including outriggers and ground conditions, rigging and slinging, communication and signalling, operating and travelling techniques, emergency response, and maintenance and defect reporting. Preparation works best in layers: learn the terminology and load chart maths first, practise inspection and setup routines until they are automatic, then drill lifting, travelling, and shutdown sequences under supervision. Always confirm current licensing requirements with your local regulator.
What you'll study
About High Risk Work Licence - Non-Slewing Mobile Crane CN preparation
What does the CN licence actually let me operate?
It covers mobile cranes that cannot slewing while supporting a load, such as pick-and-carry cranes and other non-slewing mobiles. Slewing mobile cranes need a different licence class, and some states require additional classes for particular configurations, so check your regulator's definitions before booking training.
What is the assessment format?
Expect a knowledge test of multiple-choice and short-answer questions, sometimes delivered verbally, plus a practical assessment where you inspect, set up, and operate a crane through a series of lifts. Your registered training organisation will explain the exact structure and any prerequisites before you enrol.
How long does the course and assessment take?
Training providers set their own schedules, and duration depends on your experience and whether you choose a full course or assessment-only pathway. The official body publishes the current licensing and assessment requirements, so check its website rather than relying on second-hand estimates.
How hard is the CN assessment?
Most candidates who prepare steadily pass. The common stumbling blocks are load chart interpretation, calculating lift capacity with deductions, and remembering inspection and shutdown steps under pressure. Practical control of the crane is usually easier for people with machine experience than the written theory.
What if I fail a component?
Retake arrangements are set by your training organisation and the regulator, not by a single national rule. Ask your provider about reassessment fees and waiting periods before you enrol, and confirm the current policy on the official regulator's website.
How long is the licence valid, and how do I renew?
High risk work licences are typically issued for a fixed period and must be renewed before expiry, with renewal usually requiring an application and fee rather than a full reassessment. The exact validity period and renewal process are published by your state or territory regulator.
What study order do you recommend?
Start with legislation, terminology, and crane configuration so the rest makes sense. Then master load charts and capacity calculations, followed by inspection, setup, and stability. Finish with rigging, signalling, operating techniques, emergency procedures, and record keeping, then run practice questions across all domains.
Why do candidates lose marks in the practical?
Frequent causes are skipping pre-start checks, misjudging ground conditions or outrigger setup, incorrect sling selection or inspection, poor communication with the dogger, and rushing the shutdown and park-up sequence. Assessors mark safety behaviours as closely as they mark the lift itself.
Can I use a calculator or reference materials in the test?
Rules vary between training organisations and regulators. Load chart questions may require mental arithmetic or a supplied calculator, and most tests do not allow reference charts. Confirm what is permitted with your provider so you practise under the same conditions.
Is this page affiliated with the regulator?
No. This is independent study material to help you prepare. For authoritative information on licensing, fees, assessment instruments, and current requirements, always consult your state or territory work health and safety regulator's official website.
