Sometimes loader is longitudinally truncated forming an adjacent debris-bin vertical transport.

Side loader rises from a low, manual loading position to an upper inverted dump position whereat loader displaces debris into truck bed box. Scoop's loader edge is planarly coextensive or inboard truck sidewall, and at or beneath the truck wheel axis line. A chassis mounted, articulated boom, with longitudinally extending arm segments, terminates in a grapple jaw. The articulated boom and grapple jaw has a longitudinally foreshortened stored position in and above the truck bed.
