Verified model comparison
A fleet-sizing comparison that keeps body, loading height and haul-road requirements visible.
Treat these as different haul-truck scales rather than interchangeable purchase options. Match rated payload and installed body to material density, loader reach and the intended production plan. Model queueing at the loader and dump point before assuming a larger truck will reduce the number of machines required.
The 777 reference includes a manufacturer front-canopy height on a loaded basis. It is not a verified unladen transport height. Check body shape, tires, suspension condition and actual transport preparation for either truck; the table’s configuration notes are part of the comparison, not optional fine print.
Ask whether the workshop, lifting equipment, tire-handling resources and haul-road maintenance plan support the selected truck. Inspect body cracks, hoist condition, wheel ends and braking records using qualified personnel. Obtain machine-specific repair quotes rather than projecting the smaller truck’s service costs onto the larger one.
Generation/configuration-aware: measurement basis and reference configuration travel with each value. A difference in basis is not treated as a performance difference.
