High Risk Work Licence - Slewing Mobile Crane C1 (100t) study plan

Identify the major structural and capacity-defining components of a slewing mobile crane and state the function of each

Explain how rated capacity is derived from the load chart and why it differs from the crane's maximum lifting capacity

Locate and interpret the load chart zones for a given boom length, radius and counterweight configuration

State the legislative duties of the crane operator, dogger and person conducting a business or undertaking under WHS law

Calculate net rated capacity by deducting all lifting gear, hook block and attachment masses from the gross figure

Determine working radius for at least ten practice scenarios and read the corresponding capacity from a chart

Estimate the mass of common loads using volume, density and manufacturer data, and record the method used

Locate the centre of gravity of asymmetric loads and explain how its position affects sling tension and stability

Carry out a systematic pre-operational inspection of a crane and record defects against a checklist

Assess ground bearing pressure and decide whether outrigger mats, pads or an engineered pad are required

Identify hazards for a given site and rank them using a documented risk assessment process

Select and justify control measures using the hierarchy of control for at least five crane-specific hazards

Demonstrate and correctly interpret the standard hand signals used for slewing mobile crane operations

Demonstrate and correctly interpret whistle signals, including emergency stop

Explain the responsibilities of the dogger, rigger and operator in a two-way communication chain, including radio protocol

Select slings and lifting gear for given loads and calculate tension in each leg of a two-leg and four-leg sling assembly

Identify and reject damaged or non-compliant lifting gear against inspection criteria

Draft a lift plan for a complex lift, including hazard controls, rigging arrangement, personnel roles and contingency measures

Classify lifts as routine, complex or personnel-lifting and state the additional controls each class requires

Explain the planning, load-sharing and communication requirements for a multi-crane lift and the conditions under which it must not proceed

Define exclusion zones for a given lift and justify their size and marking

State the additional controls and prohibitions that apply to lifting personnel

Determine the safe approach distance to overhead powerlines and apply the correct control measures for each voltage category

Identify environmental hazards including wind, heat, lightning, poor visibility and ground water, and state the operational limits each imposes

Plan a lift that requires travel with a suspended load and state the conditions that must be met

Apply site-specific hazard controls for confined space, traffic management and public interface

Describe the correct shutdown and securing sequence for a slewing mobile crane at the end of a shift

Outline the scheduled maintenance and inspection regime, including who may perform each task and how records are kept

List the records the operator must complete and the retention and reporting obligations attached to them

Explain the immediate response to a crane incident, including making the area safe, notifying authorities and preserving the scene

Apply basic first aid priorities for crush injury, suspension trauma and electrical contact until help arrives

Consolidate duty-of-care and regulatory knowledge by answering mixed practice questions across all ten domains

Rehearse a full lift planning exercise from hazard identification through to post-lift record completion

Review every incorrect practice answer and write the correct reasoning for each

State the notification and reporting obligations triggered by a notifiable incident
