# The pairing: the tippers a loader fills, passes per body, loads and tonnes an hour (haul_km, shift_hours, density, fill, state)

> The pairing for a loading machine: the tippers it fills, with passes per body, loads and tonnes an hour at the haul, shift, material density and bucket fill given; state picks the tippers' prices. The page a figure was read from never leaves through a key: source URLs and verification pages are dropped.
