High Risk Work Licence - Slewing Mobile Crane C1 (100t) study guide
High Risk Work Licence - Slewing Mobile Crane C1 (100t) · Work through your exam, one topic at a time.
The Slewing Mobile Crane C1 licence is an Australian high risk work licence for operating slewing mobile cranes with a rated capacity above 20 tonnes and up to and including 100 tonnes. It suits crane operators, rigging crews and construction or heavy-industry workers who need to plan and perform lifts with larger mobile plant. The High Risk Work Licence - Slewing Mobile Crane C1 (100t) study guide has 10 sections and about 3,227 words.
01Legislative and regulatory requirements for slewing mobile crane operation
High risk work licensing sits inside a layered framework you must be able to name and apply. At the top is general work health and safety law imposing a primary duty on the person conducting a business or undertaking to eliminate or minimise risk so far as reasonably practicable.
317 words, about 2 min02Duty of care, standards and the hierarchy of control
Duty of care is personal as well as organisational. As an operator you owe a duty to yourself, your dogman, other workers, the public and property.
319 words, about 2 min03Hazard identification, risk assessment and control measures
Hazard identification for crane work is systematic. Consider the task, the plant, the environment and the people.
290 words, about 1 min04Crane types, configurations, load charts and rated capacities
You must know the crane you operate. Slewing mobile cranes include truck-mounted, rough-terrain, all-terrain and crawler types.
297 words, about 1 min05Rigging, slinging, load estimation and centre of gravity
Rigging transfers the load safely from pick to placement. You must understand sling types and their limits: chain, wire rope, synthetic webbing and roundslings, each with tags, working load limits and inspection criteria.
311 words, about 2 min06Pre-operational inspection, set-up, stabilisers and ground conditions
Pre-operational inspection is a documented routine. Walk around the crane checking structure for cracks and deformation, welds, pins and retainers, rope for broken wires, kinks, corrosion and correct spooling, hook for throat opening, wear and latch function, brakes, clutches, hydraulics for leaks, tyres or tracks, lights, alarms, limiters and the rated capacity indicator.
276 words, about 1 min07Crane operation, communication, hand and whistle signals
Safe operation depends on smooth, predictable control inputs and unambiguous communication. One person, the dogman or rigger, should direct the lift, and only one.
295 words, about 1 min08Lifting plans, multi-crane lifts, personnel lifting and exclusion zones
A lifting plan documents the lift: load mass and centre of gravity, rigging, crane position and configuration, radius, chart capacity, ground conditions, environmental limits, personnel roles, communication and contingencies. Routine lifts may use a generic plan; complex, high-risk or unfamiliar lifts need a specific, engineered plan.
292 words, about 1 min09Powerline, environmental and site-specific hazards
Electricity is unforgiving. Treat all lines as live unless the network operator confirms de-energisation and isolation in writing.
259 words, about 1 min10Shutdown, securing, maintenance and record-keeping
Shutdown is a procedure, not an afterthought. Lower the load, land and secure it, retract the boom to the travel position, stow the jib, retract outriggers, engage travel locks, apply parking brake, chock wheels, and shut down per the manufacturer.
