01Occupational Health and Safety, Legislation, and Regulatory Compliance
This domain checks whether you can locate and apply the OHS duties, crane-specific rules, and certification requirements that govern mobile crane work in Canada. Most occupational health and safety law is provincial or territorial; federal rules apply in federally regulated workplaces.
378 words, about 2 min02Rigging, Load Calculation, and Lift Planning
This domain tests whether you can determine load weight, select and inspect rigging, calculate sling tension, and build a lift plan that controls the load. The exam expects working knowledge of sling configurations, working load limits (WLL), centre of gravity, sharp-edge protection, and critical-lift triggers.
406 words, about 2 min03Crane Setup, Site Preparation, and Ground Conditions
This domain tests whether you can position a mobile crane safely, assess ground bearing, deploy outriggers correctly, and recognize site hazards that affect stability. The exam focuses on load distribution, mats and cribbing, level and compaction, buried services, swing clearance, and the difference between on-outrigger and on-tire ratings.
396 words, about 2 min04Crane Inspection, Maintenance, and Pre-Operational Checks
This domain tests whether you can perform and document daily pre-operational checks, recognize defects, and understand periodic and annual inspection requirements. The exam emphasizes wire rope, hooks, safety devices, brakes, hydraulics, outriggers, and the difference between a walk-around check and a formal inspection.
392 words, about 2 min05Crane Operation and Load Handling
This domain tests whether you can apply the load chart during operation, control the load smoothly, and avoid side loading, shock loading, and instability. The exam focuses on radius, boom length, quadrants, deductions, travel restrictions, and power-line and wind limits.
384 words, about 2 min06Crane Assembly, Disassembly, and Transport
This domain tests whether you can follow manufacturer's assembly and disassembly procedures, plan lifts for boom and counterweight components, and prepare a crane for legal transport. The exam covers pins and keepers, torque, assist-crane capacity, centre of gravity, blocking, tie-down, and transport permits.
376 words, about 2 min07Communication, Signalling, and Hand Signals
This domain tests whether you can direct a crane safely using standardized hand signals, radio communication, and clear stop signals. The exam expects you to know who may signal, when to stop, and how to handle blind lifts and lost communication.
406 words, about 2 min08Documentation, Load Charts, and Record Keeping
This domain tests whether you can read a load chart correctly, apply footnotes and deductions, and keep the records that prove the crane and lift were controlled. The exam focuses on chart interpretation, range diagrams, inspection logs, lift plans, certification records, and defect documentation.
