Lift Plan, Load Weight, Radius and Capacity
Check weight, configuration, boom length, radius, chart deductions, dynamic effects and change control before lifting.
How to study crane and rigging decisions
Practice like a lift supervisor: verify competent people, calculate the actual lift, protect the ground, inspect every lifting point, control the load path, stop for communication or weather failures, and document defects before the next shift inherits them.
Core concepts
Concept 1
Verify load weight from reliable documents, calculation or weighing, then compare total lifted weight with the crane chart.
Exam cue: verified load weight
Concept 2
Stop and recalculate capacity at the actual radius and configuration; revise the lift plan if margin or route changes.
Exam cue: radius change capacity
Concept 3
Include the load, hook block, spreader beam, slings, shackles and all below-hook gear in the calculation.
Exam cue: deduct rigging weight

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.
Guardrail: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Memory anchors
verified load weight
Verify load weight from reliable documents, calculation or weighing, then compare total lifted weight with the crane chart.
radius change capacity
Stop and recalculate capacity at the actual radius and configuration; revise the lift plan if margin or route changes.
deduct rigging weight
Include the load, hook block, spreader beam, slings, shackles and all below-hook gear in the calculation.
no side loading
Do not side-pull; free the load by approved means, confirm vertical lift conditions, then lift within the plan.
Official source check
Verify eligibility, forms, fees, validity, and safety requirements with State Factories Inspectorates / Directorate of Industrial Safety and Health / Sector skill and lifting-equipment 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.

Check-up Questions
A load weighs 8.0 tonnes. The hook block weighs 0.6 tonne and the slings, shackles, and spreader weigh 0.4 tonne. What gross lifted load must be checked against crane capacity?
At the planned boom length and 12 m radius, the applicable chart capacity is 10.0 tonnes. The load is 9.5 tonnes and suspended accessories total 0.8 tonne. What does the calculation show?
Answer all questions to submit.
