1What is the current national unit of competency for a C2 High Risk Work Licence to operate a slewing mobile crane up to 20 tonnes?

A.TLILIC0022 Licence to operate a slewing mobile crane (up to 20 tonnes)

B.TLILIC0023 Licence to operate a slewing mobile crane (up to 60 tonnes)

C.TLILIC0040 Licence to operate a non-slewing mobile crane

D.TLILIC0024 Licence to operate a vehicle loading crane

Explanation: training.gov.au lists TLILIC0022 as the unit specifying skills and knowledge to safely operate a slewing mobile crane with a Maximum Rated Capacity (MRC) up to 20 tonnes. That unit underpins the C2 HRWL class.

2Under Australian mobile crane High Risk Work hierarchy, which lower classes does a C2 licence encompass?

A.CN (non-slewing mobile crane) and CV (vehicle loading crane)

B.C6 and C1 only

C.Tower crane (CT) and self-erecting tower crane (CS)

D.Bridge and gantry crane (CB) only

Explanation: SafeWork SA and SafeWork NSW licensing guidance state that a C2 slewing mobile crane licence (up to 20 t MRC) encompasses/incorporates the CN (non-slewing mobile crane) and CV (vehicle loading crane) classes. Higher slewing classes (C6, C1, C0) encompass C2 plus those lower classes. Note: the SafeWork NSW HRWL hierarchy table also lists reach stacker (RS) under C2; SA’s published mobile-crane hierarchy text focuses on CN and CV.

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: TLILIC0022 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 C2 slewing mobile crane licence class?

A.Up to 20 tonnes

B.Up to 60 tonnes

C.Up to 100 tonnes

D.Over 100 tonnes

Explanation: Class C2 covers slewing mobile cranes with an MRC up to 20 tonnes. C6 is up to 60 t, C1 up to 100 t, and C0 is over 100 t.

5According to TLILIC0022 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: Unit delivery guidance states loads must be moved by a licensed HRW DG class dogger. The C2 operator works with the dogger for communication, load path, and attachment of lifting gear as required.

6What is the primary duty of care of a licensed C2 crane operator under the WHS Act?

A.Take reasonable care for their own health and safety and ensure their acts or omissions do not adversely affect others

B.Guarantee production quotas even if load-chart limits must be exceeded

C.Personally redesign the crane’s rated capacity limiter settings without manufacturer approval

D.Delegate all hazard identification solely to the principal contractor

Explanation: Under the model WHS Act, workers must take reasonable care for their own health and safety and ensure their conduct does not adversely affect others. Crane operators remain responsible for operating within manufacturer limits and site controls.

7When is a Safe Work Method Statement (SWMS) required for crane work on a construction site?

A.When the work is high-risk construction work as defined in the WHS Regulations (e.g. near overhead electric lines or risk of falling more than 2 m)

B.Only when the crane is hired rather than owned

C.Only on weekends

D.Never — SWMS are optional guidance documents only

Explanation: WHS Regulations require an SWMS for high-risk construction work. Mobile crane operations often trigger this (for example work near overhead electric lines, or where a person could fall more than 2 metres).

8Before working near overhead powerlines with a mobile crane, what is the preferred control hierarchy action where reasonably practicable?

A.Have the lines de-energised or re-routed so the work can proceed outside electrical risk

B.Ignore voltage and always use a 1-metre clearance

C.Touch the lines briefly with an insulated tag line to confirm they are live

D.Rely only on the crane computer without a site risk assessment

Explanation: WHS guidance on work near electric lines prioritises eliminating the hazard by de-energising or re-routing lines where reasonably practicable. If that is not practicable, maintain mandated exclusion zones and other controls from a risk assessment and the electrical entity’s requirements.

9For overhead electric lines up to 132 kV, Queensland mobile crane Code of Practice guidance commonly cites a minimum exclusion distance of:

A.3 metres between any part of the crane or load and the line (greater distances for higher voltages)

B.300 millimetres

C.50 metres for all voltages

D.No clearance is required if the boom is painted yellow

Explanation: Queensland electrical exclusion-zone guidance (and industry materials referencing the Mobile crane Code of Practice) cite a minimum 3 metre exclusion for overhead lines up to 132 kV, with greater distances for higher voltages (commonly 6 m between 132 kV and 330 kV, and 8 m over 330 kV). Always confirm the applicable state requirements and the electrical asset owner’s conditions before working near lines.

10If the voltage of overhead lines cannot be confirmed before a lift, what is the safer planning approach?

A.Assume a higher-voltage clearance requirement until the electrical asset owner confirms the voltage

B.Use the smallest published clearance to maximise reach

C.Proceed without exclusion zones if the dogger says it looks safe

D.Slew under the lines with the boom fully retracted only

Explanation: When voltage is uncertain, treat the lines as higher voltage and maintain the larger applicable clearance until the electrical entity confirms otherwise. Guessing a smaller clearance is a common cause of contact incidents.

About the High Risk Work Licence — Slewing Mobile Crane C2 (20t) Exam

The C2 High Risk Work Licence authorises operation of a slewing mobile crane with a Maximum Rated Capacity (MRC) up to 20 tonnes. Assessment is based on TLILIC0022 Licence to operate a slewing mobile crane (up to 20 tonnes). Under the mobile-crane HRWL hierarchy, C2 encompasses the CN (non-slewing mobile crane) and CV (vehicle loading crane) classes (SafeWork NSW’s hierarchy table also lists RS under C2). The assessment covers planning lifts, hazard controls (including powerline exclusion zones), crane setup and outriggers, load-chart interpretation and rounding between chart values, 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 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

High Risk Work Licence — Slewing Mobile Crane C2 (20t) 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 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.

4Outriggers: full extension unless an approved partial-extension chart (or auto-limiting sensing) applies; if any outrigger is short-legged without sensing, the partial chart governs the full 360° slew.

Frequently Asked Questions

What unit of competency applies to the C2 slewing mobile crane licence?

The current national unit is TLILIC0022 Licence to operate a slewing mobile crane (up to 20 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 C2 licence allow operation of CN and CV cranes?

Yes. Under the mobile crane High Risk Work hierarchy used by Australian WHS regulators, a C2 slewing mobile crane licence (up to 20 tonnes MRC) encompasses the CN non-slewing mobile crane and CV vehicle loading crane classes. SafeWork NSW’s published hierarchy table also lists reach stacker (RS) under C2; 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.
