Before using a number from a listing, ask which object it describes: the miniature, the real machine, or the shipping package. Mixing those three produces comparisons that look precise but answer the wrong question.
Read the object before the unit
| Listing detail | Use it for | Do not use it for |
|---|---|---|
| Miniature length, width or height | Display planning, with the measurement pose identified | Opening clearance that was not measured |
| Real-machine payload or engine power | Understanding the represented subject | The miniature’s load capacity or motor performance |
| Shipping-box dimensions | Packaging space | The model or complete set’s display footprint |
| Nominal scale | The stated size relationship | A guarantee that every measured detail follows it exactly |
Why the AD45 name is not a miniature load rating
The full-size 45-tonne capacity is information about the subject. It does not authorize loading the model. The 85717 inspection discussed in its review describes a display load insert, which is a separate model feature.
