High Risk Work Licence - Slewing Mobile Crane C2 (20t) study plan
High Risk Work Licence - Slewing Mobile Crane C2 (20t) · Give each week a clear focus.
8 weeks · About 6 hours per week
Slewing mobile crane operation and load handling & Crane types, terminology, capacity and configuration
Describe the three primary controls (luff, slew, hoist) and their safe operating limits for a slewing mobile crane up to 20 tonnes
Explain load moment and how radius, boom length and counterweight affect capacity
Identify the main crane components and terminology from a labelled diagram
State the pre-start and operational checks required before any lift
Your checkpoint
A one-page annotated diagram of a slewing mobile crane with all major components and controls labelled and a short written explanation of load moment.
Slewing mobile crane operation and load handling & Rigging, slinging and load calculations
Calculate load weight, sling tension and centre of gravity for simple and multi-leg lifts
Select and inspect slings and rigging hardware for a given load
Plan a lift using a load chart, including derating for configuration and conditions
Demonstrate correct use of tag lines and load orientation during slewing
Your checkpoint
A completed lift plan for a 12-tonne load including rigging selection, load chart extract and a step-by-step slewing sequence.
Hazard identification, risk assessment and control measures & Site preparation, crane positioning and ground conditions
Conduct a written risk assessment for a lift near an excavation and overhead powerlines
Identify ground-bearing pressure requirements and select appropriate crane positioning
List control measures for common hazards: wind, ground collapse, exclusion zones and public access
Explain the process for verifying ground conditions and setting out rigging positions
Your checkpoint
A risk assessment and safe work method statement (SWMS) for a simulated lift in a confined site with identified hazards and controls.
Legislative and regulatory requirements, standards and duty of care & Pre-operational inspections, checks and maintenance
Summarise the duty-of-care obligations of the crane operator, dogger and person conducting a business or undertaking (PCBU)
Identify the relevant Australian Standards and legislative requirements for high-risk work
Perform a pre-operational inspection checklist and document defects
Explain the maintenance and inspection regimes for lifting equipment
Your checkpoint
A completed pre-operational inspection checklist with a defect log and a short written summary of legislative duties.
Communication, signalling and teamwork & Slewing mobile crane operation and load handling
Demonstrate standard hand signals and radio communication protocols for crane operations
Describe the roles of the dogger, rigger and crane operator during a lift
Execute a simulated multi-step lift using clear communication and signal acknowledgement
Identify communication failures and describe corrective actions
Your checkpoint
A video or role-play demonstration of a lift using correct hand signals and radio calls, with a self-assessment checklist.
Emergency procedures, incident response and shutdown & Hazard identification, risk assessment and control measures
Outline emergency procedures for powerline contact, load drop, crane collapse and fire
Describe the shutdown sequence for a slewing mobile crane after an incident
Conduct a simulated emergency response drill and record the steps taken
Review risk controls and update the risk assessment based on the drill outcomes
Your checkpoint
An emergency response drill report including timeline, actions taken and recommendations for improvement.
Post-operational procedures and equipment securing & Pre-operational inspections, checks and maintenance
Perform post-operational shutdown and securing procedures for a slewing mobile crane
Complete a maintenance and defect reporting process after a shift
Explain the requirements for crane immobilisation and securing at the end of the day
Audit a pre-operational inspection against the maintenance schedule
Your checkpoint
A post-operational checklist and maintenance log entry for a simulated end-of-shift procedure.
Legislative and regulatory requirements, standards and duty of care & Hazard identification, risk assessment and control measures & Crane types, terminology, capacity and configuration & Pre-operational inspections, checks and maintenance & Rigging, slinging and load calculations & Site preparation, crane positioning and ground conditions & Slewing mobile crane operation and load handling & Communication, signalling and teamwork & Emergency procedures, incident response and shutdown & Post-operational procedures and equipment securing
Complete a full practice exam under timed conditions
Review incorrect answers and map them to the relevant domain
Revisit weak areas with targeted study and practical scenarios
Confirm readiness by achieving a pass mark on a second practice exam
Your checkpoint
A scored practice exam with a written reflection and a personalised revision plan for any remaining gaps.
Milestones
Week 2: Correctly calculate load weight and sling tension for three different load configurations and select the correct rigging gear.
Week 4: Complete a pre-operational inspection and risk assessment with no critical omissions, verified against a checklist.
Week 6: Demonstrate the correct emergency response sequence for a powerline contact scenario within 2 minutes.
Week 8: Achieve at least 90% on a timed practice exam covering all domains.
