High Risk Work Licence - Bridge and Gantry Crane (CB) study guide
High Risk Work Licence - Bridge and Gantry Crane (CB) · Work through your exam, one topic at a time.
The Bridge and Gantry Crane (CB) licence is a high risk work licence that authorises you to operate bridge and gantry cranes, including overhead travelling cranes, in Australian workplaces. It is aimed at people who already work around cranes or want to move into crane operation: doggers and riggers, warehouse and yard staff, manufacturing and precast plant operators, and maintenance personnel who use cranes to move loads. The High Risk Work Licence - Bridge and Gantry Crane (CB) study guide has 10 sections and about 3,134 words.
01Work Health and Safety Legislation, Duty of Care and Licensing
Bridge and gantry crane operation sits inside a general work health and safety (WHS) framework. In Australia the model WHS Act and Regulations apply, with each jurisdiction having its own regulator and minor variations.
370 words, about 2 min02Hazard Identification, Risk Assessment and Risk Control
Risk management is a cycle: identify hazards, assess risk (likelihood × consequence), apply controls using the hierarchy, then monitor and review. The hierarchy of control runs from elimination, substitution, engineering controls, administrative controls, down to PPE as the last line.
313 words, about 2 min03Crane Types, Components, Terminology and Load Charts
Bridge cranes span between runway beams and travel along the runway; gantry cranes carry their own legs on rails or wheels at ground level, so they can run outdoors or over long spans. Variants include semi-gantry (one leg on a rail, one end on a building runway), monorail hoists, jib cranes (not CB) and portal cranes.
344 words, about 2 min04Pre-operational Checks, Inspection and Maintenance
Pre-operational checks catch faults before they become incidents. They are required by the WHS Regulations and by the manufacturer's manual, and must be recorded.
331 words, about 2 min05Operational Planning: Load Estimation, Slinging, Rigging and Communication
Operational planning starts with the load: mass, centre of gravity, shape, fragility and lifting points. Estimate mass from drawings, markings or calculations; never guess.
332 words, about 2 min06Crane Operation: Hoisting, Traversing, Travel, Positioning and Load Control
Operate smoothly: take up slack slowly, lift clear of the ground, pause to check stability and balance, then move. Avoid shock loading, sudden stops and swinging.
282 words, about 1 min07Emergency Procedures, Incident Response and Shutdown
Know the emergency stops, isolation points, fire equipment and evacuation routes before you operate. Emergency procedures cover power failure, brake failure, load drop, collision, fire, electrical contact and personal injury.
281 words, about 1 min08Worksite Communication, Teamwork, Signage and Exclusion Zones
Clear communication prevents collisions, dropped loads and crush injuries. Brief the team before the lift: roles, signals, radio channel, exclusion zone and emergency stop.
281 words, about 1 min09Environmental and Site-Specific Considerations
Every site has conditions that affect crane operation. Identify them in planning: wind, heat, cold, rain, lightning, dust, noise, lighting, ground conditions, overhead and underground services, and nearby operations.
316 words, about 2 min10Post-Operational Procedures, Logbooks, Handover and Shutdown
Post-operational procedures close the loop. Lower the load, land it on stable ground, remove slings and gear, and return the hook to a safe parked position.
