1What is the current national unit of competency for a C1 High Risk Work Licence to operate a slewing mobile crane up to 100 tonnes?
A.TLILIC0021 Licence to operate a slewing mobile crane (up to 100 tonnes)
B.TLILIC0022 Licence to operate a slewing mobile crane (up to 20 tonnes)
C.TLILIC0023 Licence to operate a slewing mobile crane (up to 60 tonnes)
D.TLILIC0020 Licence to operate a slewing mobile crane (over 100 tonnes)
Explanation: training.gov.au lists TLILIC0021 as the unit specifying skills and knowledge to safely operate a slewing mobile crane with a Maximum Rated Capacity (MRC) up to 100 tonnes. That unit underpins the C1 HRWL class.
2Under Australian mobile crane High Risk Work hierarchy, which lower classes does a C1 licence encompass?
A.C6, C2, CN (non-slewing mobile crane), CV (vehicle loading crane) and RS (reach stacker)
B.C0 only
C.Tower crane (CT) and self-erecting tower crane (CS)
D.Bridge and gantry crane (CB) only
Explanation: SafeWork NSW’s published HRWL hierarchy table shows that a C1 slewing mobile crane licence (up to 100 t) authorises the lower classes C6, C2, CV, CN and RS. Some regulator prose summaries list C6, C2, CN and CV without naming RS — always confirm the current state hierarchy chart. C0 is a higher over-100 t class and is not encompassed by C1.
3A slewing mobile crane is best defined as a mobile crane that:
A.Incorporates a boom or jib capable of being slewed (rotated about a vertical axis)
B.Can only travel with a load and cannot rotate the superstructure
C.Is always mounted permanently on a building portal frame
D.Is limited to earthmoving plant configured as a crane
Explanation: TLILIC0021 and WHS guidance define a slewing mobile crane as a mobile crane incorporating a boom or jib that can be slewed. Earthmoving plant configured for crane work is generally excluded from this definition for licensing purposes.
4What is the Maximum Rated Capacity (MRC) limit for the C1 slewing mobile crane licence class?
A.Up to 100 tonnes
B.Up to 20 tonnes
C.Up to 60 tonnes
D.Over 100 tonnes
Explanation: Class C1 covers slewing mobile cranes with an MRC up to 100 tonnes. C2 is up to 20 t, C6 up to 60 t, and C0 is over 100 t.
5According to TLILIC0021 assessment conditions, who may sling and direct loads during competent crane operation assessment?
A.A licensed dogger or rigger (HRW DG pathway / dogging or rigging class)
B.Any site labourer who has watched a toolbox talk
C.The crane operator alone without a dogger when the load is in sight
D.Only a rigger with an RA advanced rigging licence
Explanation: training.gov.au assessment conditions for TLILIC0021 require appropriate personnel to sling and direct loads, including a licensed dogger or rigger. The C1 operator follows their directions for communication, load path, and attachment of lifting gear as required.
6Competence in TLILIC0021 alone:
A.Does not itself issue the High Risk Work Licence; the HRWL is issued by the state/territory WHS regulator after satisfactory assessment
B.Automatically grants a C0 licence for over-100 t cranes
C.Replaces the need for any practical assessment
D.Is valid only in the state where the RTO is headquartered and never elsewhere
Explanation: Unit materials state competence in the unit does not in itself result in an HRWL. After Notice of Satisfactory Assessment, the candidate applies to the relevant WHS regulator for the licence class.
7A Safe Work Method Statement (SWMS) for high-risk construction crane work should identify:
A.Hazards, risk controls, and how the work will be done safely for the specific task
B.Only the crane brand colour
C.The operator’s preferred radio station
D.A guarantee that no hazards exist
Explanation: SWMS documents how high-risk construction work will be carried out safely, including hazards and controls. Generic or empty statements do not meet planning duties.
8Before working near overhead powerlines, the operator should:
A.Confirm line voltage/asset owner requirements and maintain the required exclusion zone (or obtain an authorised approach permit/procedure)
B.Assume all lines are low voltage and boom under them freely
C.Touch the line with a steel tagline to test if it is live
D.Rely only on the RCI alarm without checking clearances
Explanation: Powerline contact is a leading crane fatality cause. Confirm voltage with the electrical asset owner and apply the mandated exclusion zone or authorised approach controls before operating near lines.
9When a tagline is used near overhead powerlines, guidance typically requires:
A.A dry non-conductive (e.g. dry natural fibre) rope of adequate diameter, not a conductive metal rope
B.A steel wire rope for maximum strength near lines
C.No tagline ever when any powerline exists on the same suburb
D.A wet hemp rope soaked in water to improve grip
Explanation: Training materials for TLILIC0021 note that a dry non-conductive or dry natural-fibre tagline must be used near overhead powerlines, and cite minimum diameter guidance (commonly 16 mm as the smallest diameter for that duty). Conductive ropes increase electrocution risk.
10PCBU and worker WHS duties for crane operations include:
A.Taking reasonably practicable steps to eliminate or minimise risks and following safe systems of work
B.Ignoring site rules if the lift is behind schedule
C.Operating without induction if you hold any HRWL
D.Leaving hazard controls optional for experienced operators
Explanation: Under model WHS law, PCBUs must ensure health and safety so far as reasonably practicable, and workers must take reasonable care and comply with reasonable instructions and procedures.

About the High Risk Work Licence — Slewing Mobile Crane C1 (100t) Exam

The C1 High Risk Work Licence authorises operation of a slewing mobile crane with a Maximum Rated Capacity (MRC) up to 100 tonnes. Assessment is based on TLILIC0021 Licence to operate a slewing mobile crane (up to 100 tonnes). Under the SafeWork NSW mobile-crane HRWL hierarchy table, C1 encompasses C6, C2, CN (non-slewing mobile crane), CV (vehicle loading crane) and RS (reach stacker); some regulator prose summaries name only C6/C2/CN/CV — confirm your state chart. The assessment covers planning lifts, hazard controls (including powerline exclusion zones), crane setup and outriggers, load-chart interpretation, net capacity calculations (gross rated capacity minus hook-block and rigging deductions), dogger communication (hand, whistle, and radio signals), safe crane movements, and shutdown/securing.

Assessment

Closed-book National Assessment Instrument (NAI) theory and calculation assessment administered by an accredited assessor at an RTO, plus a practical crane operation assessment. Loads are slung and directed by a licensed dogger or rigger.

Time Limit

Closed-book NAI theory and calculation papers plus practical assessment (session timing set by the accredited assessor)

Passing Score

Competent — calculations and practical require 100% accuracy; critical safety theory items must be answered correctly

High Risk Work Licence — Slewing Mobile Crane C1 (100t) Study Tips from Top Performers

1Drill net capacity: Net capacity = gross rated capacity from the correct load-chart cell minus all applicable deductions (hook block, slings, fly jib when applicable).
2Memorise powerline exclusion-zone principles and always confirm voltage with the electrical asset owner before working near overhead lines.
3Practise radius problems: working radius is the horizontal distance from the centre of rotation (slew ring) to the centre of the load — use the next higher chart radius when between listed values.

Frequently Asked Questions

What unit of competency applies to the C1 slewing mobile crane licence?

The current national unit is TLILIC0021 Licence to operate a slewing mobile crane (up to 100 tonnes). Competence in the unit supports the High Risk Work Licence pathway; the HRWL itself is issued by the state or territory WHS regulator after a Notice of Satisfactory Assessment.

Does a C1 licence allow operation of C6, C2, CN, CV and RS plant?

Yes on the SafeWork NSW HRWL hierarchy table: C1 (up to 100 t) encompasses C6, C2, CN, CV and RS. Some regulator prose pages list C6, C2, CN and CV without naming RS — confirm your state/territory hierarchy chart. C1 does not authorise C0 (over 100 tonnes).

What happens if I fail the calculation component of the NAI?

NAI crane calculations require 100% accuracy. Failing any calculation item results in Not Yet Competent for that component and requires reassessment per the assessor's and regulator's rules.
