1What is the current national unit of competency for a C6 High Risk Work Licence to operate a slewing mobile crane up to 60 tonnes?
A.TLILIC0023 Licence to operate a slewing mobile crane (up to 60 tonnes)
B.TLILIC0022 Licence to operate a slewing mobile crane (up to 20 tonnes)
C.TLILIC0021 Licence to operate a slewing mobile crane (up to 100 tonnes)
D.TLILIC0040 Licence to operate a non-slewing mobile crane
Explanation: training.gov.au lists TLILIC0023 as the current unit for safely operating a slewing mobile crane with MRC up to 60 tonnes. It supersedes TLILIC0013 and underpins the C6 HRWL class.
2Under Australian mobile crane High Risk Work hierarchy, which lower classes does a C6 licence encompass?
A.C2 (slewing up to 20 t), CN (non-slewing), and CV (vehicle loading crane)
B.C1 and C0 only
C.Tower crane (CT) and self-erecting tower crane (CS)
D.Bridge and gantry crane (CB) only
Explanation: SafeWork NSW licensing guidance states a C6 licence (slewing mobile crane up to 60 t) incorporates C2, CN and CV. C6 does not authorise higher slewing classes C1 (up to 100 t) or C0 (over 100 t). SafeWork NSW’s published hierarchy table also lists reach stacker (RS) under C6; confirm RS encompassment with your state regulator.
3What is the Maximum Rated Capacity (MRC) limit for the C6 slewing mobile crane licence class?
A.Up to 60 tonnes
B.Up to 20 tonnes
C.Up to 100 tonnes
D.Over 100 tonnes
Explanation: Class C6 covers slewing mobile cranes with an MRC up to 60 tonnes. C2 is up to 20 t, C1 up to 100 t, and C0 is over 100 t.
4A 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: TLILIC0023 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 for licensing purposes.
5Does competence in TLILIC0023 alone automatically issue a High Risk Work Licence?
A.No — the unit supports the pathway; the HRWL is issued by the state/territory WHS regulator after Notice of Satisfactory Assessment
B.Yes — the Statement of Attainment is the licence card
C.Yes — any RTO certificate replaces the regulator licence
D.Only if the crane is under 20 tonnes
Explanation: Unit materials state competence in the unit does not in itself result in an HRWL. Candidates need a Notice of Satisfactory Assessment from an accredited assessor, then apply to the state regulator (e.g. via Australia Post in NSW).
6According to TLILIC0023 performance expectations, who must move the loads during competent crane operation assessment?
A.A person holding a High Risk Work Licence class DG (dogging)
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: Delivery guidance requires loads to be moved by a licensed HRW DG class dogger. The C6 operator works with the dogger for communication, load path and attachment of lifting gear as required.
7Can a C6 licence holder legally operate a C2-class slewing crane (up to 20 t)?
A.Yes — C6 encompasses C2 under the mobile crane HRWL hierarchy
B.No — a separate C2 ticket is always required
C.Only if the crane is fitted with a fly jib
D.Only interstate, never in the home state
Explanation: Under the mobile-crane HRWL hierarchy, C6 incorporates C2 (and CN/CV). A C6 holder may operate C2-capacity slewing plant; a C2 holder may not operate plant requiring C6. C6 still does not authorise C1 or C0.
8Before operating near overhead powerlines, the operator should:
A.Confirm voltage/asset details with the electrical asset owner and apply required exclusion zones and controls
B.Assume all lines are low voltage and work to 1 m clearance
C.Touch the boom briefly to the line to test for current
D.Ignore lines if a spotter is present without other controls
Explanation: Working near powerlines requires confirmed voltage information, correct exclusion zones (or formal permits/approaches), spotters and other hierarchy controls. Guessing voltage is unsafe.
9A Safe Work Method Statement (SWMS) for high-risk construction crane work is used to:
A.Document hazards, control measures and the safe method for the task
B.Replace manufacturer load charts
C.Authorise exceeding rated capacity for short lifts
D.Prove the crane never needs a pre-start check
Explanation: SWMS capture how high-risk construction work will be done safely. They complement — not replace — load charts, manufacturer limits and pre-start checks.
10Traffic management around a C6 crane set-up is confirmed so that:
A.Workers, vehicles and the public are kept clear of slewing/load paths and exclusion zones
B.The crane can travel on public roads without any escort or permits ever
C.Pedestrians may walk under suspended loads if wearing hi-vis
D.Only the operator needs to know vehicle routes
Explanation: Unit planning requirements include confirming traffic management so operating and load paths remain controlled. Pedestrians must never walk under suspended loads.

About the High Risk Work Licence — Slewing Mobile Crane C6 (60t) Exam

The C6 High Risk Work Licence authorises operation of a slewing mobile crane with a Maximum Rated Capacity (MRC) up to 60 tonnes. Assessment is based on TLILIC0023 Licence to operate a slewing mobile crane (up to 60 tonnes), which supersedes TLILIC0013. Under the mobile-crane HRWL hierarchy, C6 encompasses C2 (slewing up to 20 t), CN (non-slewing mobile crane) and CV (vehicle loading crane); it does not authorise C1 (up to 100 t) or C0 (over 100 t). SafeWork NSW’s hierarchy table also lists reach stacker (RS) under C6—confirm RS with your state regulator. The assessment covers planning lifts, hazard controls (including powerline exclusion zones), crane setup with outriggers/counterweights/fly jib as required, load-chart interpretation, net capacity calculations (gross rated capacity minus hook-block, fly 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 must be moved with a licensed HRW DG class dogger.

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

Exam Fee

RTO courses commonly advertise about $2,000–$3,500 AUD for training and assessment (depending on provider and state), plus a separate state/territory HRWL application fee typically around $75–$110 AUD (State and Territory Work Health and Safety (WHS) regulators (e.g., SafeWork NSW, WorkSafe Victoria, WorkSafe Queensland, SafeWork SA) using the national unit TLILIC0023)

High Risk Work Licence — Slewing Mobile Crane C6 (60t) 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, erected/stowed fly deductions when applicable).
2Memorise the hierarchy: C6 encompasses C2, CN and CV — but not C1 or C0.
3Practise chart rounding: working radius is the horizontal distance from the slew-ring centre to the load centre—when between listed radii, use the next longer (worse) radius unless chart notes say otherwise; when boom length is between listed lengths, use the lesser capacity of the next longer and next shorter boom lengths at that radius.

Frequently Asked Questions

What unit of competency applies to the C6 slewing mobile crane licence?

The current national unit is TLILIC0023 Licence to operate a slewing mobile crane (up to 60 tonnes). It supersedes TLILIC0013. 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 C6 licence allow operation of C2, CN and CV cranes?

Yes. Under the mobile crane High Risk Work hierarchy used by Australian WHS regulators (e.g. SafeWork NSW), a C6 slewing mobile crane licence (up to 60 tonnes MRC) encompasses C2 (up to 20 t), CN (non-slewing mobile crane) and CV (vehicle loading crane). It does not authorise C1 or C0. SafeWork NSW’s published hierarchy table also lists reach stacker (RS) under C6; confirm your state regulator’s hierarchy chart for RS.

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.
