Lifting, Load Chart and Rigging
Use load charts, radius, boom angle, attachment capacity, sling condition, centre of gravity, taglines, and signal control.
How to study construction equipment operation
Practice like an authorized plant operator: verify the machine, read site conditions, respect load and stability limits, control people around equipment, stop for power lines or defects, and document every safety-critical decision.
Core concepts
Concept 1
Stop and recalculate capacity at the actual radius and configuration before continuing the lift.
Exam cue: radius change capacity
Concept 2
Do not lift until the attachment is approved for the machine and its rated capacity is known for the planned configuration.
Exam cue: attachment capacity
Concept 3
Remove the damaged sling from service, tag it, select rated gear in good condition, and update the lift check.
Exam cue: damaged sling

Risk pitfalls and guardrails
Treating verbal permission as written authorization.
Guardrail: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Proceeding without recording readings, isolation, PPE, or exposure-control evidence.
Guardrail: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Choosing a generic answer without checking state variation or the latest official notice.

Memory anchors
radius change capacity
Stop and recalculate capacity at the actual radius and configuration before continuing the lift.
attachment capacity
Do not lift until the attachment is approved for the machine and its rated capacity is known for the planned configuration.
damaged sling
Remove the damaged sling from service, tag it, select rated gear in good condition, and update the lift check.
single signal control
Stop the lift, confirm the designated signal person and communication method, then resume only with clear single-point direction.
Official source check
Verify eligibility, forms, fees, validity, and safety requirements with Infrastructure Equipment Skill Council / Construction skill and site-safety authorities or the current state authority notice.
Stop-work cue
If identity, authorization, isolation, PPE, exposure limits, or emergency controls are unclear, stop work and escalate.
Record cue
Exam-safe answers protect written records, competent sign-off, instrument readings, and traceable corrections.
Shortcut trap
Fast results, verbal approval, copied certificates, and undocumented adjustments are common trap answers.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
