Figures are the makers’ own, for the set-up shown in the first row; they change with boom, arm, bucket, shoes and counterweight. Power and digging forces use the standard named in each row; makers measure some figures slightly differently, so treat small gaps with care. “–” means the maker doesn’t publish that figure. Imperial values are converted from metric.
