1What is the current national unit of competency for a CB High Risk Work Licence to operate a bridge and gantry crane?
A.CPCCLDG3001 Licence to perform dogging
B.TLILIC0020 Licence to operate a slewing mobile crane (over 100 tonnes)
C.TLILIC0016 Licence to operate a bridge and gantry crane
D.TLILIC0006 Licence to operate a bridge and gantry crane
Explanation: training.gov.au lists TLILIC0016 as the current unit specifying skills and knowledge to safely operate bridge and gantry cranes. That unit underpins HRWL class CB. Completing the unit alone does not issue the licence card.
2What is the High Risk Work Licence class code for bridge and gantry crane operation?
A.CN
B.CT
C.CB
D.CV
Explanation: Australian WHS regulators use class CB for bridge and gantry cranes. CN is non-slewing mobile crane, CT is tower crane, and CV is vehicle loading crane.
3Per Safe Work Australia, a bridge crane is best defined as a crane that:
A.Is limited to earthmoving plant configured with a hook
B.Has legs supporting the bridge beam so the crane travels on ground-level supporting surfaces only
C.Is always mounted on a truck chassis with a telescopic boom
D.Consists of bridge beam(s) mounted to end carriages, travels along elevated runways, and has one or more hoisting mechanisms arranged to traverse across the bridge
Explanation: Safe Work Australia’s bridge and gantry crane HRW information sheet defines a bridge crane by elevated runway travel with hoist mechanisms traversing the bridge beam(s).
4Per Safe Work Australia, a gantry crane is best defined as a crane that:
A.Is any overhead hoist fixed permanently to a single beam with no travel
B.Consists of bridge beam(s) supported at one or both ends by legs mounted to end carriages, can travel on supporting surfaces or deck levels, and has a crab with one or more hoisting units travelling across the bridge
C.Is always a slewing mobile crane with outriggers
D.Travels only on elevated building runways with no supporting legs
Explanation: Safe Work Australia defines a gantry crane by legs (or end supports) allowing travel on supporting surfaces/decks, with a crab/hoist travelling across the bridge.
5A Bridge and Gantry Crane (CB) HRW licence is required to operate a bridge or gantry crane that is:
A.Used solely for manufacturer commissioning without any load ever
B.Controlled from a permanent cabin or control station on the crane, or remotely controlled with more than three powered operations
C.Any overhead monorail hoist regardless of control type
D.Remotely controlled with a maximum of three powered operations only
Explanation: Safe Work Australia states CB is required for cabin/control-station operation, or remote control with more than three powered operations. Remote plant with ≤3 powered operations is outside the CB licence trigger.
6For licensing purposes, how are hoist raise and hoist lower counted as powered operations on a bridge or gantry crane?
A.Raise and lower together count as one powered operation (hoisting)
B.Raise and lower each count as separate powered operations
C.Hoisting is never counted as a powered operation
D.Only lowering counts; raising is ignored
Explanation: Safe Work Australia’s information sheet states hoisting — raising and lowering — are considered one powered operation.
7Which of the following is typically counted as an independent powered operation of a bridge or gantry crane for CB licensing?
A.Traversing — movement of the crab along the bridge
B.Powered rotation provided only by a rotator attachment on the hook
C.Switching a lifting magnet on or off
D.Opening and closing a grab on the hook
Explanation: Safe Work Australia lists traversing, travelling, hoisting, and rotating of the crane support structure as typical powered operations. Hook/attachment functions such as grabs, magnets, vacuum switches, and hook rotators are not powered operations for this count.
8A remotely controlled gantry crane has traverse, travel and hoist only. Is a CB HRW licence required?
A.Yes — any remote gantry crane always requires CB
B.Yes — any gantry crane over 1 tonne requires CB regardless of motions
C.No — remote operation never requires any HRW licence
D.No — a maximum of three powered operations does not require CB
Explanation: Safe Work Australia states a CB licence is not required to remotely operate a bridge or gantry crane that only has a maximum of three powered operations (for example traverse, travel and hoist).
9A remotely controlled gantry with four powered operations (traverse, travel, hoist and powered structure rotation) is used in a shipyard. Is a CB licence required?
A.No — only cabin-operated cranes ever require CB
B.Yes — remote control with more than three powered operations requires CB
C.Yes — but only if the load exceeds 10 tonnes
D.No — shipyard work is exempt from all HRW licences
Explanation: Safe Work Australia examples confirm remote plant with more than three powered operations requires a Bridge and Gantry HRW licence.
10Does competence in TLILIC0016 by itself issue a High Risk Work Licence card?
A.No — CB licences are issued only by Safe Work Australia directly to operators
B.Yes — any RTO certificate is automatically a national licence
C.Yes — the Statement of Attainment is the licence card
D.No — the unit supports the pathway; the state/territory WHS regulator issues the HRWL after satisfactory assessment
Explanation: TLILIC0016 states competence in the unit does not in itself result in an HRWL. Candidates complete NAI assessment and apply to the relevant state/territory WHS regulator for class CB.

About the High Risk Work Licence — Bridge and Gantry Crane (CB) Exam

The CB High Risk Work Licence authorises operation of bridge and gantry cranes that are controlled from a permanent cabin or control station on the crane, or remotely controlled with more than three powered operations (hoist raise/lower counts as one operation), including load estimation and slinging techniques to move a load. Assessment is based on TLILIC0016 Licence to operate a bridge and gantry crane. Content covers WHS planning and hazards, bridge vs gantry definitions, powered-operation counting, pre-operational checks and limit switches, long/cross travel and hoist control, load weight/CG estimation, sling selection and SWL calculations, AS 2550.1-aligned signals, dogger interface when loads are out of view, emergency stop, and shutdown/securing with out-of-service tagging.

Assessment

Closed-book National Assessment Instrument (NAI) theory and calculation assessment administered by an accredited assessor at an RTO, plus a practical bridge/gantry crane operation assessment. Unit elements cover plan work/task, prepare, perform, and pack up. Many RTOs require a Dogging (DG) licence and/or logged operating hours before practical assessment.

Time Limit

Closed-book NAI theory and calculation papers plus practical assessment (session timing set by the accredited assessor; courses commonly run 3–5 days face-to-face)

Passing Score

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

Exam Fee

RTO courses commonly advertise about $1,400–$2,000+ AUD for CB training and assessment (examples: ~$1,400 Integral Skills NSW; ~$1,795 Training Combined NSW + ~$90 licence fee; ~$2,000 Saferight WA; fees vary by location and funding), plus a separate state/territory HRWL application fee typically around $75–$160 AUD (State and Territory Work Health and Safety (WHS) regulators (e.g., SafeWork NSW, WorkSafe Victoria, WorkSafe Queensland, WorkSafe WA, SafeWork SA) using the national unit TLILIC0016)

High Risk Work Licence — Bridge and Gantry Crane (CB) Study Tips from Top Performers

1Memorise Safe Work Australia’s powered-operation count: traverse, travel, hoist (raise/lower = one), and powered rotation of the crane support structure; hook rotators, grabs, magnets and vacuum switches are not powered operations for licensing.
2Drill load estimates using steel ≈ 7,850 kg/m³ and concrete ≈ 2,400 kg/m³, then compare total mass (plus lifting gear) to the crane’s rated capacity and any site SWL limits.
3Practise two-leg included-angle factors (SWL ≈ WLL_single × factor): 0°=2.0, 60°≈1.73, 90°≈1.41, 120°=1.0 — and know AS 2550.1-aligned whistle signals (hoist up 2 short; lower 1 long; stop 1 short).

Frequently Asked Questions

What unit of competency applies to the CB bridge and gantry crane licence?

The current national unit is TLILIC0016 Licence to operate a bridge and gantry crane. 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. Completing the unit alone does not issue the licence card.

When is a CB licence required for bridge or gantry cranes?

Safe Work Australia guidance requires a CB HRW licence to operate a bridge or gantry crane controlled from a permanent cabin or control station on the crane (regardless of powered-operation count), or remotely controlled with more than three powered operations (hoisting raise and lower counts as one). Remote plant with a maximum of three powered operations (e.g. traverse, travel and hoist) does not require CB.

Does a CB licence include load estimation and slinging?

Yes. The CB class includes applying load estimation and slinging techniques to move a load when operating bridge or gantry plant. CB holders still need a dogger (or rigger) to direct the load when it is out of the operator’s view, and CB does not authorise dogging on other crane classes.
