Common miss
Direct answer
The common mistake is treating What determines which load-chart capacity applies to a lift as a loose phrase instead of a rule, condition, or field decision with consequences. Load-chart capacity is configuration-specific and must match the actual setup and operating radius. If you miss this area, review the explanation, tag the weak concept, and drill nearby topics such as Crane safety concepts, Basic load chart practice, Signals and communication.
How to use this answer
Read the answer once, then prove it by choosing an answer in a practice question before looking at the explanation. If the miss repeats, tag the domain as Load charts and drill a smaller set before returning to mixed practice.
