High Risk Work Licence - Slewing Mobile Crane C0 (over 100t) study guide
High Risk Work Licence - Slewing Mobile Crane C0 (over 100t) · Work through your exam, one topic at a time.
The C0 Slewing Mobile Crane licence is an Australian high risk work (HRW) competency for operating slewing mobile cranes with a rated capacity over 100 tonnes. It suits experienced crane operators moving up from smaller capacity classes, and people working on major construction, infrastructure, mining, energy and heavy industrial projects where large all-terrain, truck-mounted or crawler-based slewing cranes are used. The High Risk Work Licence - Slewing Mobile Crane C0 (over 100t) study guide has 10 sections and about 3,347 words.
01Legislative, Regulatory and Duty-of-Care Requirements for Slewing Mobile Cranes over 100 t
High-risk work licensing sits inside a layered system. The model WHS Act and Regulations (mirrored in each state and territory, with variations) impose a primary duty of care on the person conducting a business or undertaking (PCBU) to eliminate or minimise risks so far as is reasonably practicable.
394 words, about 2 min02Hazard Identification, Risk Assessment and Control
Hazard identification for heavy lifts starts with the task, the plant, the people and the environment. Walk the crane path, the load path, and the landing zone.
387 words, about 2 min03Crane Types, Configurations and Load Charts for Cranes over 100 t
Large slewing mobile cranes include all-terrain and rough-terrain truck cranes, lattice-boom crawler cranes, and telescopic-boom crawlers. Each has a load chart specific to boom configuration, counterweight, outrigger or track spread, and optional equipment such as jib, fly, luffing jib, superlift or boom extension.
363 words, about 2 min04Rigging, Slinging and Load Estimation
You must know the load's mass and centre of gravity before selecting gear. Sources include the data plate, drawings, weighbridge tickets and calculation.
361 words, about 2 min05Site Preparation, Ground Conditions and Outrigger Set-up
Most crane collapses on large machines trace to ground or set-up failure. You need to know the maximum outrigger or track load, which the manufacturer publishes, and compare it with the ground's bearing capacity.
359 words, about 2 min06Planning and Performing Lifts, Including Multi-Crane and Critical Lifts
A lift plan documents the load, mass, radius, configuration, chart capacity, rigging, ground conditions, personnel, controls, sequence and contingencies. Critical lifts, such as those over occupied areas, near powerlines, with tandem or multi-crane arrangements, or with unusual loads, demand a higher level of engineering and approval.
317 words, about 2 min07Communication, Teamwork and Lift Coordination
Every lift has a defined chain: the crane operator, the dogman or rigger, and the person in control. Only one person should give signals to the operator at a time.
290 words, about 1 min08Crane Inspection, Maintenance and Defect Reporting
Know the difference between pre-start checks, periodic inspections and maintenance. Pre-start checks cover fluids, tyres, brakes, hydraulics, wire rope, hooks, safety devices, load moment indicator, alarms, lights and outriggers.
274 words, about 1 min09Emergency Procedures, Incident Response and Shutdown
Emergency planning covers powerline contact, fire, hydraulic failure, brake failure, load drop, structural failure, collapse, injury, and severe weather. Know the location of firefighting equipment, first aid, emergency contacts and assembly points.
311 words, about 2 min10Safe Operation, Shutdown and Post-Operational Procedures
Safe operation is the application of everything planned: correct configuration, verified ground, confirmed load and radius, controlled swing, smooth starts and stops, no shock loading, and constant monitoring. Avoid side loading the boom, dragging loads, and rapid slewing that induces swing.
