Data notes

†

Derived value. tipping load was not published directly in a usable form by the source. It was reconstructed from related published figures and accepted only after validating against the expected relationship between specifications for this machine class.

Method. Figures are manufacturer reference specifications, not measurements. Every value is checked for unit consistency, physically possible magnitude, and plausibility for its equipment class before publication; figures that fail any check are withheld rather than shown, and figures reconstructed from related data are marked above. Imperial and metric figures are reproduced as published, except where a note states otherwise.
